Silicone Rubber & Sponge

Silicone Rubbers are ideal for high- and low-temperature applications. Electrical properties are excellent and resistance to weathering and ozone attack is outstanding. Silicone is not resistant to super-heated steam. Physical properties are generally low but are at least retained at higher temperatures. Gas permeability is very poor as is resistance to petroleum-based fluids. Silicone rubbers are expensive in comparison to most other rubbers. Food Quality/FDA-compliant grades are available for use in the food and pharmaceutical industries.

Silicone is a semi-organic elastomer with outstanding resistance to extremes of temperature with corresponding resistance to compression set and retention of flexibility. Silicone elastomers provide excellent resistance to ozone, oxygen, and moisture. Low physical strength and abrasion resistance combined with high friction properties limit silicone to static seal applications. Silicone utilizes a flexible siloxane backbone rather than a carbon backbone like many other elastomers and has very low glass transition temperatures.

Die-Cut Products stocks a broad spectrum of sponges & rubbers for your custom fabrication needs. This includes both solid rubbers as well as open-cell and closed-cell sponge rubbers. All materials are available with full cure date, shelf life, and supplier test reports right from the mill. Need RoHS-compliant material? We offer that too!

Benefits of Silicone Rubber & Sponge

Some of the benefits of silicone include excellent properties when exposed to extreme temperatures, excellent compression set resistance, and a very clean, low-odor taste. When compared to other rubbers, the maximum temperature range of Silicone is typically superior.
Typical temperature range for Silicone is -75°F to +450 °F
