Silicone Sponge UL 94 V-0 | Flame Retardant | National Silicone

UL 94 V-0 Flame Retardant Silicone Sponge

Medium Closed Cell Silicone Sponge Rubber

This medium firm closed cell flame retardant silicone sponge passed 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.

Medium Flame Retardant Silicone Sponge

It is typically a grey or black color and is rated UL 94 V-0. The material is produced with a fabric impression on both sides, is flexible and offers excellent compression set resistance.

More Information

UL 94 V-0

  • UL 94 V-0 is a safety and flammability standard by Underwriters Laboratories.
  • 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.

 

AMS3195

  • AMS3195 is an aerospace material specification is from SAE International Group.
  • The specification covers silicone rubber sponge in the form of sheet, strip, extrusions, and molded shapes.
  • Our medium density silicone sponge sheet is in accordance with the physical property requirements of AMS3195 test standard.
  • This product has been used typically for general applications requiring closed-cell, medium sponge rubber that will be flexible from -103 to +401 °F (-75 to +205 °C), but usage is not limited to such applications. Compression set may be high at the higher temperature.
