Commercial Silicone Sponge
Silicone Elastomers provide the maximum in
reliability, whether exposed to adverse environmental conditons, stored for
indefinite periods or used under normal conditions. Silicone resists temperature
extremes, ozone, corona, radiation, compression set, moisture, weathering, and a
wide range of chemicals. Colors other than red are available special order.

Viton Sponge
Viton sponge is a closed cell, soft density
foam that is manufactured with a continuous skin on both sides. The skin
makes the sheet stronger and more tear resistant and even when the surface
skin is punctured or cut, the material will not allow the passage of air or
fluid between cells. The non- absorbent sheets are highly compressible,
resilient, lightweight and provide good thermal insulation. Like dense Viton,
this material is generally resistant to aliphatic and aromatic hydrocarbons,
oil, fuels, ozone and weather, lubricants, and animal or vegetable oils. It
is also resistant to acids and hot water. Optional pressure sensitive
adhesive (PSA) is available.

*Elevated temperatures while under compression will have an
adverse effect on the resilience of the material.
Polyurethane Foam (Polyester)
This material is a low cost, lightweight, open cell polyurethane foam
generally used as weather stripping, sealants, and gaskets for noise
deadening and insulation. Generally available in 2, 4, and 6 lb. densities
with and without a pressure sensitive adhesive.
