kSil® V-0 Super Soft Flame-Resistant Silicone Sponge — Technical Overview & FAQs
Product Overview
kSil® V-0 Super Soft Flame-Resistant Silicone Sponge is an ultra-compliant, closed-cell silicone sponge engineered for low-pressure sealing, thermal insulation, and flame-critical applications.
It meets the stringent UL 94 V-0 flame rating, providing exceptional fire resistance while maintaining a soft, conformable structure that seals delicate surfaces without excessive compression force.
kSil® V-0 is ideal for electronics, EV battery packs, lighting enclosures, HVAC components, and industrial equipment requiring reliable sealing across extreme temperatures. Its closed-cell construction ensures moisture resistance, environmental protection, and dimensional stability in both indoor and outdoor environments.

FAQs
What is kSil V-0 Super Soft Silicone Sponge used for?
It is used for fire-rated sealing, thermal insulation, and environmental protection in electronics, EV systems, appliances, aerospace components, and other flame-critical applications.
What makes this silicone sponge “super soft”?
The formulation creates a low-density, low-compression-force material that easily conforms to uneven surfaces—ideal for low fastening loads or fragile housings.
Is kSil V-0 suitable for outdoor use?
Yes — its silicone chemistry delivers excellent UV, ozone, and weather resistance, making it suitable for long-term indoor and outdoor environments.
How does the UL 94 V-0 rating benefit my application?
UL 94 V-0 ensures the sponge is self-extinguishing, produces minimal flame spread, and is acceptable for fire-sensitive electrical and mechanical assemblies.
Can kSil V-0 be die-cut or adhesive-backed?
Yes — H-O Products provides custom die-cut seals, strips, and PSA-backed gaskets, ready for production-line installation.
