Flexible, compressible COHRlastic silicone closed cell sponge is designed for high-performance gasketing, thermal shielding, vibration mounts and press pads. It is available in six constructions.
R10470, a general-purpose silicone sponge, can be used in most applications.
R10480 has extremely low compression set and maintains its resiliency even under extended compression.
R10460 is flame retardant.When held in a vertical position and exposed to a 2,000 °F flame for 12 seconds, there is nomore
