More Information

AMS3196

  • AMS3196 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 firm density silicone sponge sheet is in accordance with the physical property requirements of AMS3196 test standard.
  • This product has been used typically for general applications requiring closed-cell, firm sponge rubber that will be flexible from -75 to +205 °C (-103 to +401 °F), but usage is not limited to such applications. Compression set may be high at the higher temperature.
