UL 94 V-0 Flame retardant Silicone Sponge

This medium firm closed cell flame retardant silicone sponge is typically a grey or black color and is rated UL 94 V-0 (more info below). Passing the vertical burn test, which is more stringent than horizontal test (HB), is seen as a critical safety standard for applications where flame and fire protection is of the highest importance. The material is produced with a fabric impression on both sides, is flexible and offers excellent compression set resistance.

ams3195

  • This medium frim, fire retardant, silicone sponge sheet is in accordance with the physical property requirements of AMS3195 test standard.
  • The specification covers sheets, rolls, strips, extrusions and molded shapes. Typically used for general purpose applications and remains flexible from -103 to +401oF (-75 to +205oC).

UL 94 V-0

  • This material is compliant with the UL 94 V-0 test standard for flammability.
  • The vertical burn test measures the self-extinguishing time of a vertically oriented polymer specimen.
  • The test evaluates both the burning and afterglow times and dripping of the burning test specimen.
  • In order to be rated UL 94 V-0, the burning must stop within 10 seconds, no flame propagation or dripping.
