Silicone

Polycraft produces silicone rubber and fluorosilicone custom molded components required in technology-driven applications.

We primarily process silicone in the form of high consistency gum stock rubber which is either compression molded or transfer molded. These compounds are inventoried from 25 to 80 durometer Shore A, while speciaty silicones are compounded on request. These silicones can be formulated for high elongation, flex, tensile and tear properties, and can withstand temperatures from -100°F to 500°F. Gum based silicones are formulated to meet industrial and military specifications such as ZZ-R-765 and AA-59988.

Reinforced Silicone

Reinforced silicone is silicone rubber with additional layers of fiberglass or other material, woven in to increase the overall tear resistance and to decrease material strain. We also bond reinforced silicone to alloys and composite assemblies.

Fluorosilicone

Fluorosilicone rubber is specified for applications requiring the broad temperature range and age resistance of silicone rubber, along with resistance to fuels, coolants and oils that would damage silicone rubber.

Silicone Foam and Silicone Sponge

Both the liqid based Silicone Foam, and the gum based Silicone Sponge have combined properties of resilience, high temperature stability and general inertness unavailable in other foam or sponge gasketing and cushioning materials. They are generally unaffected by extended exposure to temperature extremes from -67°F (-55°C) to 392°F (200°C), and are also unaffected by aging and degradation from sunlight and ozone.

Silicone foam is typically lighter in density, compresses with less force and has a lower compression set than silicone sponge. Both products have good sealing properties; however the sponge has higher tensile strength and the foam has better flame resistance.
