Silicone Foam for Electronics and EV Battery Packs

In the transportation sector, designing lighter weight components has widely become a key trend especially to reduce energy consumption and maximize the range of electric vehicles. CHT’s advanced Silicone Foam is designed to reduce weight – as well as mitigate thermal runaway and provide protection from moisture, debris, vibration and shock for electronic components and EV battery packs. CHT’s silicone foam is also ideal where low smoke, flame and toxicity are required.

CHT’s SilSo Lite 21025 is a two-part, room temperature platinum cure, self-blowing silicone foam which creates a closed-cell structure. It is formulated as a liquid system with a 1:1 mix ratio by volume and low viscosity, enabling easy dispensing either by cartridge or automated mixing machine. 

This silicone foam’s fast gel time will help increase production throughput and features primerless adhesion to a variety of substrates. Additionally, improved adhesion can be achieved by using one of CHT’s recommended primers. SilSo Lite 21025 will expand 2-3 times its liquid volume and will reach full cure in about 10 minutes. 

Addressing safety requirements, SilSo Lite 21025 exhibits excellent flame retardancy which will help mitigate a thermal runaway event. Independent testing is in progress to certify that SilSo Lite 21025 meets the UL 94 V-0 rating.
