#emi shielding

Excessive exposure to certain types of electromagnetic radiation can be harmful. The higher the frequency of radiation, the more damage it may cause to the body. For example, X-rays can damage cells, causing mutations and cell death-and gamma rays can also damage cells, causing mutations and cell death. Therefore, the harm of radiation is very harmful to our human body.

But if you want good protection against radiation, you may need this! ! !

EMI shielding/RFID electromagnetic wave interference/electromagnetic wave protection cloth can be used for bags, curtains, tents, etc. It can effectively block mobile phone towers, microwave oven signals, mobile phones, smart instruments, security systems, radars, military broadcasts, etc.;

And I believe that for pregnant women, electromagnetic waves are more harmful to them.

I don’t know if you guys have any ideas?

The ev composites market is emerging as a critical defense layer for the complex electronics, battery trays, and high-voltage wiring setups that power the modern green fleet. Unlike older internal combustion vehicles that feature scattered mechanical components, an electric car centralizes its core energy assets inside a massive floor-mounted pack. This layout leaves the most expensive component of the vehicle vulnerable to debris impacts, ground scraping, and ambient moisture intrusion during daily road operations. To mitigate these significant risks, forward-thinking automotive engineers are designing highly durable battery enclosures utilizing custom-formulated, impact-resistant composite compounds that deliver absolute security.

The thermal management requirements of modern high-output lithium batteries are exceptionally demanding, requiring materials that can isolate heat while providing a robust structural shell. Traditional aluminum battery trays conduct external heat far too efficiently, posing severe challenges during fast-charging cycles where battery temperatures can spike rapidly. Engineered composites feature exceptionally low natural thermal conductivity, functioning as a built-in insulation shield that protects battery modules from external climate extremes. This natural thermal barrier reduces the energy load required by internal liquid cooling systems, boosting the vehicle's net energy efficiency while extending the lifecycle of the battery cells.

Beyond thermal insulation, advanced automotive composites provide exceptional electromagnetic interference shielding, which is vital for preserving the integrity of delicate onboard sensor networks. The massive electrical currents flowing through an electric vehicle's powertrain generate powerful magnetic fields that can potentially disrupt autonomous driving sensors and wireless communication modules. By infusing specialized conductive fibers directly into the composite matrix blend, engineers can create a highly effective shield that blocks unwanted electrical noise. This multi-functional material performance proves that advanced polymers are far more than simple structural substitutes; they are highly integrated electronics enclosures.

The strategic industrial significance of these advanced material formulations is a key highlight within comprehensive EV Composites industry updates published by international chemical and automotive research councils. Statistically, the EV Composites market was valued at USD 1.62 Billion in 2023 and is projected to grow to USD 4.11 Billion by 2030, with a compound annual growth rate (CAGR) of 15.0% from 2024 to 2030. These numbers outline the massive commercial opportunities awaiting raw material suppliers who can successfully manufacture high-performance, flame-retardant resins at a global commercial scale.

The rise of electric vehicles (EVs) is reshaping the global automotive industry, and with it comes a growing demand for robust electromagnetic interference (EMI) shielding solutions. As EVs rely heavily on a dense array of electronic components—ranging from power inverters, battery management systems, onboard chargers, and infotainment units to advanced driver-assistance systems (ADAS)—ensuring electromagnetic compatibility (EMC) has become a top priority. EMI shielding plays a vital role in protecting these systems from internal and external electromagnetic noise, which can lead to signal disruption, safety concerns, or system failures.

One of the dominant market trends in EMI shielding for EVs is the shift towards lightweight and multifunctional materials. With automotive manufacturers aiming to improve energy efficiency and extend driving range, traditional heavy metal enclosures are being replaced with advanced composites, conductive polymers, nanomaterials, and EMI coatings that offer effective shielding while minimizing weight. The demand for sprayable, printable, or conformal shielding materials is also rising, especially for applications where complex geometries or compact packaging is involved.

Another significant trend is the growing integration of EMI shielding at multiple levels of the vehicle’s electrical architecture. Shielding is now being applied not only to enclosures and cables but also at the PCB level and within connectors, sensors, and battery packs. This multi-layered approach is becoming essential as EV platforms scale up in voltage and power density. The rollout of 800V systems and fast-charging technologies, for instance, has introduced new EMI challenges that require advanced shielding strategies capable of operating at higher frequencies and thermal loads.

As regulations surrounding vehicle safety, emissions, and electromagnetic compliance tighten worldwide, OEMs and Tier 1 suppliers are increasingly investing in EMI shielding to meet industry standards such as ISO 11452, CISPR 25, and UNECE regulations. Compliance with these standards is not only critical for safety and legal approvals but also influences consumer trust and brand reputation. As such, the market for EMI shielding in EVs is seeing robust growth across North America, Europe, and especially Asia-Pacific, where EV adoption is accelerating rapidly.

From a technological perspective, the future of EMI shielding in EVs lies in the integration of smart materials and AI-driven solutions. Materials with embedded sensing capabilities are being explored for self-monitoring and adaptive shielding, while AI-powered simulation and testing platforms are being used to optimize shielding design and predict potential interference issues before they occur. These innovations are enabling faster development cycles, reduced prototyping costs, and enhanced system reliability.

Electrically Conductive Elastomers (ECE)

EMI Non-metallic

Block EMI. In any weather, anytime.

Sometimes, the standard silicone gasket just won’t do. Differing weather conditions, operating temperatures, levels of chemical exposure, corrosion, and environmental fluctuations call for gaskets that are designed to shield electromagnetic interference in environmental-specific settings. Our electrically conductive elastomers provide environmental sealing, excellent mechanical functionality, and electromagnetic shielding so your enclosures receive the best protection possible with optimal electrical performance.

How Laird Elastomers Secure Your EMI Shields

Your closure problem usually starts like this: you’ve constructed an effective shielding system using a metal housing and lid. But when you combine the flat surfaces of both units, you notice a slight opening. Suddenly, gas, liquid, or high frequency electromagnetic energy have an easy-access path to your shielding system, which can worsen under high pressure and corrosion. Thankfully, our resilient, conductive elastomers can seal this opening by conforming to surface irregularities in your shield’s enclosure. We offer versatile forms of elastomers such as:

Diverse filler particles within our line of ElectroSeal gaskets

Wire in solid and sponge elastomers, impregnated wire mesh, and expanded metals within our line of ElectroMet gaskets

These gaskets are available in:

Flat or die cuts

Molded shapes such as O-rings or intricate parts

Extruded / coextruded profiles or strips

Vulcanized-to-metal covers or flanges

Co-molded or reinforced seals

Form-in-place gaskets

Find or Design Your Conductive Elastomer

By combining the right form and type of elastomer, you can build an ideal sealing solution that blocks electromagnetic waves while providing sufficient conductivity across your shield’s enclosure, gasket, and lid junction. Browse our catalog of elastomers or contact an engineer through our customer service department to design a conductive gasket that’s right for you.
