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 no residential flame and less than a 10 second afterglow. Like R10480, it is especially resistant to compression set.
R10450 silicone sponge with fiberglass reinforcement is a unique construction. It has the compressibility of sponge, plus dimensional stability in the X-Y direction. The absence of stretch contributes to the consistent size and shape of die cut parts and eliminates outward extrusion under pressure.
R10490 fluorosilicone sponge rubber can be used as a gasket where it is necessary to contain fluids that would degrade normal silicone sponge and solid materials (special order basis).
R10404 closed-cell conformable silicone rubber sponge is designed for use where both conformability and heat transfer are necessary, such as between printed circuit boards and heat sinks, decal transfer or applying heat activated adhesives.
