EMI Shielding Materials – Insights
Electromagnetic interference (EMI) shielding materials are materials used for preventing damages to the electronic equipments or devices due to electromagnetic interference.
The broad range of military, industrial, commercial and other applications of electronic devices is creating a new form of pollution called electromagnetic interferences (EMI). The growing complexity of the electronic systems in form of higher packing is resulting in EMI. EMI comprises of numerous undesirable radiated signals which causes unacceptable multifunctioning, degradation, or interference of the equipment. The noise coming from the car speakers while talking on the cell phones and electrostatic discharge which causes distorted static television reception are few common instances of electromagnetic interference.
EMI can cause damage to safety operations and communication systems of electronic devices. High frequency signals used in the microprocessor controlled equipments can get transmitted to the surrounding environment and cause malfunctioning to other nearby devices. EMI can also cause health hazards such as insomnia, languidness, headache, and nervousness, owing to exposure of electromagnetic radiations.
An effective method to solve such problems is the usage of EMI shielding materials. The shielding materials are mechanical devices that prevent interferences, by preventing generation of interference or picking up of interference from the outside source.
The factors fueling growth of the EMI shielding materials market are the stringent regulations on EMI emissions by the regulatory bodies such as The International Electrotechnical Commission (IEC) via its International Special Committee on Radio Interference. Increasing usage of electronic systems in various industries such as automobiles and healthcare, rapid development of 4G/LTE infrastructure, and growing demand for next generation integrated electronic circuits due to growing adoption rate of smart phones and devices are other factors augmenting growth of the market.
The expensive manufacturing of EMI shielding materials especially in major industries such as defense and aerospace is the major factor restraining growth of the EMI shielding materials market.
EMI shielding materials is classified based on components such as conductive coatings and paints, EMI shielding tapes & laminates, conductive polymers, metal shielding products and EMI filters. Among components, conductive coatings and paints is the largest segment in the EMI shielding materials market, due to its thermal properties and its easy application on nylon and plastic resins such as polyphthalamide (PPA), polyphenylene oxide (PPO), polybutylene terephthalate (PBT), polycarbonate, and polystyrene (PS). Thus, they are used in wide range of devices such as tablets, smartphones, and some others. EMI shielding tapes and laminates is estimated as the fastest growing component segment, owing to its low cost as compared to other components, easy application, and 100% shielding coverage.
EMI shielding materials is classified based on applications such as consumer electronics, telecommunication and IT, automotive, healthcare, and aerospace and defense. Among application, consumer electronics holds a dominant position in the market, owing to growing demand for smart phones, laptops, tablets, phablets, digital cameras, wearable electronic devices, intelligent security systems, kitchen appliances, and other products. The automotive application segment is the fastest growing segment, due to adoption of various features such as touchscreen infotainment system, on-board navigation system, ADAS, terrain response, V2X technology, in vehicle communication systems, wireless phone chargers among others. These features are capable of producing electromagnetic interferences, which in turn is expected to increase the demand for EMI shielding materials in automobile market.
Asia Pacific estimated as the largest and the fastest growing EMI shielding materials market and was valued at US$ 2.62 billion in 2016. This is mainly owing to rapidly growing automobile and consumer electronics industries in the region. According to the statistics provided by India Brand Equity Foundation (IBEF), the Indian OEM sector is estimated to reach US$ 16.5 billion by 2021 from US$ 7 billion in 2016. The Indian electronic market is estimated to witness a CAGR of 24.4%, to reach approximately US$ 400 billion by 2022 from US$ 69.6 billion in 2012. Also, the automobile industry in China exhibited year-on-year growth of 4.8% by production and 5.3% by sales in 2017, as per the statistics provided by the China Association of Automobiles Manufactures (CAAM).
North America is estimated as the lucrative market for EMI shielding materials, owing to various government regulations on EMI. For instance, in U.S., EMI guidelines for commercial equipment are given in The Code of Federal Regulations (CFR), section 47 in Parts 15, 18, and 68 and military guidelines are detailed in military standards such as MIL-STD-461E and MIL-STD-464.
EMI shielding materials market was valued at US$ 5.38 billion in 2016 and is projected to witness a CAGR of 6.23% in terms of revenue, during 2017 – 2025.
