EMI SHIELDING MATERIALS MARKET ANALYSIS

Electromagnetic interference (EMI) shielding materials are materials used for preventing damages to the electronic equipment or devices due to electromagnetic interference. Various features, as well as EMI shielding's capacity to regulate electromagnetic waves, have significantly contributed to the usage of EMI shielding in product manufacturing. Much research is being conducted to broaden the scope of the product so that it may be utilized in a variety of other applications. Its widespread use in consumer electronics and medical industry is expected to rise during the forecast period. For instance, in hospitals, electrocardiography machines use EMI shielding solutions to reduce the impacts of EMI radiation

Global EMI shielding materials market was valued at US$ 8.01 Bn in 2021 in terms of revenue, exhibiting a CAGR of 5.67 % during the forecast period (2022 to 2030).

Drivers

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 equipment 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.

COVID-19 pandemic has had a significant influence on the EMI shielding business. With manufacturing facilities being stopped by COVID-19 measures, very few industrial operations were allowed. Also, during the coronavirus pandemic, global vehicle sales fell significantly, as service facilities and showrooms remained closed or functioned at reduced capacity throughout the lockdown. However, considering the material's importance in increasing the performance of automobile optical equipment such as sensor systems there is a surge in demand for EMI shielding materials in the automotive sector post-COVID. All these factors have affected the revenue growth of the market

Market Restraints

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.

Market Trends

Rapid industrialization is one of the key factors driving the growth of the market. Furthermore, widespread utilization of EMI shielding in consumer electronics is also providing a boost to the market growth. In line with this, product manufacturers are using conductive coatings and paints that offer EMI shielding for non-metallic surfaces and plastics in smartphones and telecommunication, medical and military devices. Apart from this, significant growth in the automotive industry is also creating a positive impact on the market growth. EMI shielding is extensively used in this industry in GPS navigation and infotainment systems, hands-free features and Bluetooth devices to ensure minimal EMI and optimal performance of the equipment. Other factors, including various advancements in the 4G and 5G network technologies, along with the implementation of favorable government policies to minimize electromagnetic radiations in the environment, are projected to drive the market further.
