Extreme Flame Retardant Silicone FAQs

What is extreme flame-retardant silicone, and what flammability standards does it meet?

Extreme flame-retardant silicone is a high-performance elastomer compound engineered to extinguish flames quickly, limit flame spread, and emit minimal smoke and toxic fumes when exposed to open fire. ElastaPro’s extreme flame-retardant silicone sheets meet stringent safety specifications, including UL 94 V-0 flammability ratings (backed by an official UL Yellow Card) and aerospace vertical burn requirements under FAR 25.853.

What industries and applications require UL 94 V-0 and FAR 25.853 flame-retardant silicone?

Because of its exceptional Flame, Smoke, and Toxicity (FST) profile, this material is widely specified for critical safety applications in:

  • Aerospace & Aviation: Cabin interiors, light seals, HVAC ducting gaskets, and insulation blankets.
  • Mass Transit & Rail: Interior seating gaskets, door seals, and electrical enclosure seals complying with transit flame standards.
  • Electronics & Energy: High-voltage electrical enclosures, battery pack gaskets, power distribution cabinets, and circuit breaker insulation.

Can flame-retardant silicone sheeting be supplied with pressure-sensitive adhesives (PSA) or custom die-cut?

Yes. ElastaPro extreme flame-retardant silicone sheeting is easily converted, die-cut, or waterjet-cut into custom gaskets and complex sealing shapes. It can also be supplied with factory-applied flame-retardant or high-temperature pressure-sensitive adhesive (PSA) backings to streamline component placement and assembly.
