HFO FOAM STABILIZERS MARKET SIZE AND SHARE ANALYSIS - GROWTH TRENDS AND FORECASTS (2026-2033)

Global HFO Foam Stabilizers Market Size and Forecast – 2026 To 2033

The global HFO foam stabilizers market is expected to grow from USD 83.0 Mn in 2026 to USD 152.00 Mn by 2033, registering a compound annual growth rate (CAGR) of 9.0% from 2026 to 2033. The market is driven by stricter rules on high-GWP blowing agents, which are pushing foam makers of polyurethane foam insulation to switch to HFOs. On October 24, 2023, the US Environmental Protection Agency (EPA) published its final Technology Transitions rule. The rule limited the global warming potential (GWP) of foam blowing agents to 150 for new products, so many foam makers had to move to HFO-based systems and find stabilizers that work with them.

Key Takeaways of the Global HFO Foam Stabilizers Market

• The silicone polyether surfactants segment is expected to account for 77.0% of the global HFO foam stabilizers market share in 2026. Rising need for stabilizers that can handle acid formed in HFO blends is driving the growth of the segment. On September 12, 2025, Momentive Performance Materials announced that it would showcase high-purity silicones for rigid polyurethane foam at UTECH Middle East 2025. The products aimed to improve insulation and surface quality in boards, panels and appliances.
• The spray polyurethane foam segment is estimated to capture 34.0% of the market share in 2026. Strong demand for high-performance insulation in building retrofits is driving the growth of the segment. On October 30, 2025, Honeywell completed the spin-off of Solstice Advanced Materials as an independent company. The new company makes Solstice blowing agents, which are used in spray foam insulation.
• The HCFO-1233zd(E) segment is expected to account for 46.0% of the global HFO foam stabilizers market share in 2026. Wide use of this blowing agent in spray foam, appliances and panels is driving the growth of the segment. It is also the hardest HFO to stabilize, so foam makers using it need stronger stabilizer packages. On September 23, 2026, Arkema launched Foranext Continuum, a new additive for rigid polyurethane foam made with Forane 1233zd. The additive was designed to keep foam formulations consistent over time.
• North America is expected to dominate the HFO foam stabilizers market in 2026 with a market share of 42.0%.

• Asia Pacific is expected to account for 28.0% share in 2026 and is the fastest-growing region. China’s move away from the ozone-depleting blowing agent HCFC-141b is driving the growth of the regional market. On November 15, 2025, China’s Ministry of Ecology and Environment issued a ban on HCFC-141b in polyurethane foam. The ban took effect on January 1, 2026 for polyol blends, and on July 1, 2026 for spray foam.

Segmental Insights

Why Do Silicone Polyether Surfactants Dominate the Global HFO Foam Stabilizers Market?

In terms of product type, silicone polyether surfactants are expected to account for 77.0% of the global HFO foam stabilizers market share in 2026. They are the main cell stabilizer in rigid polyurethane foam. A small dose controls bubble size, closed-cell content and insulation value.

HFO systems need a tougher type of surfactant. Standard grades can break down when acid forms in the blend during storage. So, suppliers make hydrolysis-resistant grades. Evonik’s TEGOSTAB B 8409, for example, is a non-hydrolysable grade that works with pentanes, HFCs and HFOs. Grades like this let foam makers use one product across different blowing agents.

On January 22, 2025, Concentrol introduced STB PU-2272, a silicone surfactant for rigid foams made with HFCs, HFOs or pure hydrocarbons. The company said the product dissolves easily in common rigid foam polyols and helps deliver low thermal conductivity.

Why Is Spray Polyurethane Foam the Leading Application?

In terms of application, spray polyurethane foam is expected to account for 34.0% of the global HFO foam stabilizers market share in 2026. Closed-cell spray foam carries a high HFO load. It is widely used for wall and roof insulation.

Spray foam kits are often stored for months before use, so the stabilizer must hold up for a long time. Substitutes are also limited. Hydrocarbons are too flammable to spray on site. In its submission to ECHA, DuPont stated that no alternatives to HFO-1234ze(E) and HCFO-1233zd(E) existed for low-pressure spray foam.

On July 2, 2025, China’s Ministry of Ecology and Environment released a draft ban on HCFC-141b as a polyurethane blowing agent for public comment. This gave foam makers, including spray foam producers, early notice to plan their switch to alternatives such as HFOs

Why Does HCFO-1233zd(E) Lead Among Blowing Agent Types?

In terms of blowing agent type, HCFO-1233zd(E) is expected to account for 46.0% of the global HFO foam stabilizers market share in 2026. It is widely used in spray foam, appliances and panels. It also gives very good insulation.

It is the hardest HFO to stabilize. It reacts with amine catalysts more easily than other HFOs, and the acid formed damages the surfactant. So, foam makers using it need stronger stabilizer packages, often with acid-blocked catalysts. This high stabilizer need, along with its wide use, gives it the largest share.

On August 28, 2025, Arkema announced the start-up of its new 15-kiloton Forane 1233zd production unit in Calvert City, Kentucky. The company invested around US$60 million to convert an old HFC line into this HFO unit, to meet growing demand in building insulation and thermal management.

Current Events and their Impact

HFO Foam Stabilizers Market Dynamics

Market Drivers

• HFC phase-down rules are pushing foam makers to HFOs: Governments are limiting high-GWP HFCs in foam. HFC-245fa, which was widely used in closed-cell spray foam, has a GWP of about 1,030. HFOs bring this down to around 1. So, foam makers are reformulating their products with HFO blowing agents. But they cannot reuse their old surfactant packages, because HFOs behave differently in solubility and storage. Each switch needs a new stabilizer, and this creates direct demand for HFO-grade stabilizers. HFO foams also insulate well: Oak Ridge National Laboratory measured 18.3 mW/m·K in boardstock blown with HCFO-1233zd(E). This makes them a strong choice under tighter energy codes.
• On October 19, 2026, Huntsman Building Solutions presented Heatlok HFO Pro, a closed-cell spray foam for new construction and retrofit projects. The foam uses Honeywell’s Solstice HFO liquid blowing agent, which has a GWP of 1.

• Shelf-life problems are making stabilizers a critical ingredient: HFO blends are harder to keep stable than older systems. During storage, HCFO-1233zd reacts with the amine catalyst and releases hydrofluoric acid. This acid breaks down the silicone surfactant. After a few weeks, the foam can show coarse cells or even collapse. Foam makers now need stabilizer packages that hold up for months. This turns the stabilizer from a low-cost ingredient into a specified, higher-value product. On September 23, 2026, Arkema launched Foranext Continuum, a new additive for rigid polyurethane foam made with Forane 1233zd. The additive was designed to keep foam formulations consistent over time, for use in insulation, roofing and appliances.

Emerging Trends

• Bundled surfactant and catalyst packages: Suppliers increasingly sell stabilizers and catalysts as one matched set for HFO systems. Momentive’s rigid foam guide, for example, pairs HFO-compatible silicones with catalysts promoted for good shelf life with HFO-1233zd.
• Impact: Foam makers get a tested system instead of building their own. This cuts trial time and lowers the risk of foam failure.
• Relevance to the market: Value is moving toward suppliers that can offer a full package backed by ageing data. Suppliers that sell only surfactants may lose ground.
• PFAS scrutiny of HFOs: The EU’s proposed PFAS restriction covers HFOs that contain a CF3 group. Many European foam makers are keeping hydrocarbon backup formulations ready.
• Impact: Uncertainty slows HFO adoption in Europe. Some buyers delay switching until the rules are clear.
• Relevance to the market: Stabilizer suppliers with grades that work in both HFO and pentane systems are better protected. They can serve customers whichever way the EU decision goes

Regional Insights

Why Is North America a Strong Market for HFO Foam Stabilizers?

North America is expected to account for a market share of 42.0% in 2026. The region has the world’s largest spray foam industry and a strong market for insulated panels and boardstock. The US limit of 150 GWP for foam blowing agents moved most closed-cell spray foam to HFOs. Several major HFO producers also make their products here. Honeywell produces HFO-1234ze at its Baton Rouge plant, and Arkema has started a new 15-kiloton Forane 1233zd unit in Calvert City, Kentucky. Stabilizer suppliers such as Dow and Momentive are also based in the US. Having blowing agent makers, stabilizer suppliers and foam producers in one region speeds up joint formulation work.

Why Does the Asia Pacific HFO Foam Stabilizers Market Show High Growth?

Asia Pacific is expected to register the fastest growth, with a CAGR of about 12.5% over the forecast period. The region is projected to account for 28.0% of the global market in 2026. Growth comes mainly from China’s exit from HCFC-141b, which forces foam makers in spray foam, panels and cold storage to find new blowing agents. The region also has a growing base of HFO and silicone production. Chemours partnered with Zhejiang Juhua Group in China to produce more HFO-1336mzz(Z). Shin-Etsu Chemical in Japan supplies silicone surfactants to Asian appliance and building foam makers. Rising demand for cold chain and building insulation adds further support.

Global HFO Foam Stabilizer Market Outlook for Key Countries

Why Is the U.S. Emerging as a Major Hub in the HFO Foam Stabilizers Market?

The U.S. leads because of strict rules on high-GWP blowing agents and a large spray foam market. Under the EPA’s Technology Transitions rule, new foam products had to meet a GWP limit of 150 from 2025. Spray foam makers moved their closed-cell products to HFOs. Huntsman Building Solutions, for example, uses Honeywell’s Solstice HFO liquid blowing agent in its Heatlok HFO Pro spray foam. Chemours supplies Opteon 1100 for spray foam insulation. Stabilizer suppliers like Dow (VORASURF) and Momentive (Niax) also serve this market. This mix of blowing agent supply, additive supply and end use keeps the US at the center of HFO stabilizer demand.

Is China the Next Growth Engine for the HFO Foam Stabilizers Market?

China is set for strong growth after its HCFC-141b ban. The ban took effect in polyol blends and polyurethane products from January 1, 2026, and in spray foam from July 1, 2026. China also set its 2026 production quota for HCFC-141b at zero. The country’s refrigerator makers still rely mainly on cyclopentane, so HFO growth will come from construction, spray foam and cold storage. Local silicone producers such as Jiangsu Maysta Chemical, and Elkem with its operations in China, can benefit from this shift. Chemours’ HFO-1336mzz(Z) supply agreement with Zhejiang Juhua Group also adds local HFO capacity.

Germany HFO Foam Stabilizers Market Analysis and Trends

Germany is home to two of the largest silicone surfactant makers, Evonik and Wacker Chemie. Evonik’s TEGOSTAB range includes hydrolysis-resistant grades for rigid foam made with pentane, HFCs and HFOs. Even so, HFO use in Germany stays limited. According to PU Europe, pentane makes up more than 90% of blowing agent use among its members. The EU F-gas Regulation also bans F-gases in foams from 2033, unless needed for safety. So German suppliers focus on universal grades that work in both HFO and pentane systems, and they sell these grades widely outside Europe.

India HFO Foam Stabilizers Market Analysis and Trends

India phased HCFC-141b out of its foam sector from January 1, 2020. Many foam makers moved to cyclopentane, supported by the Multilateral Fund under the Montreal Protocol. HFOs are used mainly where flammability is a concern, such as spray foam and some panels. Cost is the main barrier: the Multilateral Fund noted that HFO prices in developing countries ranged from about US$15 to US$25 per kg. Even so, growing demand for cold chain and building insulation is creating room for premium HFO foams. This opens a steady, if smaller, market for HFO-grade stabilizers.

Japan HFO Foam Stabilizers Market Analysis and Trends

Japan follows the faster HFC phase-down schedule for developed countries under the Kigali Amendment. This pushes Japanese foam makers toward low-GWP options. Shin-Etsu Chemical, based in Tokyo, is a major silicone producer and supplies surfactants to appliance and building foam makers across Asia. Japan’s large appliance industry needs high-efficiency insulation in compact spaces, which suits HFO-blown foam. Japanese suppliers also benefit from strong demand in nearby Asian markets. This makes Japan both a user and an exporter of HFO-compatible stabilizers.

How Is Cost-Competitive Silicone Supply Creating New Growth Opportunities in the HFO Foam Stabilizers Market?

New silicone suppliers are entering the polyurethane foam market with lower-cost stabilizer ranges. This matters most in price-sensitive markets, where foam makers are moving away from HCFC-141b. Vertically integrated silicone producers can control raw material costs and offer custom formulations to systems houses. This gives foam makers in emerging markets more choice beyond the big global suppliers. It also increases price competition, which could make HFO-compatible stabilizers more affordable and support wider HFO adoption.

On December 5, 2025, BRB International launched its Sipostab silicone stabiliser range for the polyurethane foam industry. The range covers rigid foam, flexible foam, one-component foam and other uses. The company said its integrated silicone value chain helps it offer more cost-competitive surfactants to foam system houses.

Market Report Scope

Analyst Opinion (Expert Opinion)

• The stabilizer has become the bottleneck. In the early days of HFOs, the main concern was the price and supply of the blowing agent. Supply has since grown. The harder problem is now inside the blend: keeping an HFO mixture stable for months. HFO producers filed patents on amine–acid adducts, encapsulated catalysts and other ways to protect the surfactant. Additive makers also began promoting catalysts for their shelf life in HFO blends. As a result, value will move to suppliers that offer a tested package of surfactant, catalyst and stabilizer, backed by ageing data. Suppliers that sell only surfactants risk becoming second sources.
• Growth is expected to remain niche-led, while Europe faces a binary regulatory risk. Hydrocarbon blowing agents continue to dominate wherever their use is feasible. Pentane accounts for more than 90% of blowing agent consumption among PU Europe’s members, and HFOs remain considerably more expensive than cyclopentane in developing countries. As a result, demand for HFO foam stabilizers is likely to be concentrated in applications where hydrocarbons are less suitable, such as spray foam, thin insulation panels and cold chain. North American spray foam and Chinese construction foam therefore represent the most attractive opportunities for suppliers. In Europe, the outcome of the proposed PFAS restriction remains the principal risk. An exemption for foam applications would help sustain demand, whereas a restriction without such an exemption could lead to a significant decline. Stabilizer grades compatible with both HFO and pentane systems offer suppliers the most resilient position.
