The CHT Group Launches New Silicone Foam for Electronics and EV Battery Packs

Richmond, VA (Jan 2022) -- The CHT Group is introducing a new silicone foam during IPC APEX Expo, taking place on January 25-27th in San Diego, CA. CHT’s SilSo Lite 21025 is a two-part, room temperature platinum cure, self-blowing silicone foam which creates a closed-cell structure.

CHT’s SilSo Lite 21025 meets criteria 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. This silicone foam is also ideal where low smoke, flame and toxicity are required.

“The new, high performance lightweight silicone materials being developed by CHT will help drive innovation across many markets and applications that utilize these materials,” stated Phil McDermott, Chief Technology Officer at CHT USA. “These materials are designed to meet challenging performance criteria while keeping sustainability as a key design factor."

The SilSo Lite 21025 is designed as a liquid system with a 1:1 mix ratio 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.

Product demonstrations will take place at booth #1316:

  • Tuesday, January 25th at 2:00 p.m.
  • Wednesday, January 26th, at 2:00 p.m.
