CHT Group launches new silicone foam for electronic and EV drums

Richmond, VA (January 2022) – CHT Group showcases new silicone foam at the IPC APEX Expo, taking place January 25-27 in San Diego, CA. CHT’s SilSo Lite 21025 is a two-part, platinum-curing, room temperature, self-inflating silicone foam that creates a closed cell structure.

CHT’s SilSo Lite 21025 meets criteria for weight reduction, thermal runaway mitigation, and protection against moisture, debris, vibration, and shock for electronic components and EV batteries. This silicone foam is also ideal where low smoke, flame and toxicity are required.

“The new, high-performance, lightweight silicone materials developed by CHT will help drive innovation in many markets and applications that use these materials,” said Phil McDermott, Chief Technology Officer, CHT USA. “These materials are designed to meet demanding performance criteria while keeping durability as a key design factor.”

SilSo Lite 21025 is designed as a liquid system with a 1:1 mix ratio and low viscosity, allowing for easy dispensing either by cartridge or automated mixer.

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

Meeting safety requirements, SilSo Lite 21025 exhibits excellent flame retardance that will help mitigate a thermal runaway event. Independent testing is underway to certify that SilSo Lite 21025 meets UL 94 V-0 classification.

Product demonstrations will take place at booth #1316:

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