Silicone Rubber

Polycraft Products, Inc. produces compression mold and transfer mold custom rubber components in-house in Cleves, Ohio to service specialty applications for customers in technology-driven markets. As our core business revolves around silicone rubber and cast polyurethane technology, our strength in rubber molding includes silicone rubber compression and transfer molding and fluorosilicone compression molding and transfer molding.

Both rubber compression and transfer molding is a labor intensive production activity. When we review a potential requirement for a molded component, we consider whether the requirements include design assistance and prototyping, special rubber molding compounds, quantities and sizes that allow us to provide value.

We primarily process silicone in the form of high consistency rubber which is also known as gum stock. Silicone rubber compounds are inventoried from 25 to 80 durometer Shore A and additional specialty silicones can be compounded on request. Gum stock silicones can be formulated for high elongation, flex, tensile and tear properties for mechanically demanding applications and withstand temperatures from -100°F to 500°.Gum based silicones for compression molding and transfer molding can be formulated to meet a number of industrial and military specifications such as ZZ-R-765 and AA-59988.

Reinforced Silicone

Reinforced silicone is silicone rubber is with the addition of layers of woven fiberglass. The addition of woven fiberglass to molded silicone rubber increases tear resistance and decreases strain

Fluorosilicone

Fluorosilicone rubber is primarily specified for gasket 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. Molded fluorosilicone rubber from Polycraft Products provide these properties for your fluorosilicone rubber application.

Silicone Foam

Silicone foam rubber has the combined properties of resilience, high temperature stability and general inertness unavailable in any other foam gasketing and cushioning material. These materials 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, making it an excellent silicone foam gasket material.

UL94VO gaskets are frequently specified for cabinets used in the telecommunications and military electronics hardware. Silicone foam UL94V0 gaskets will provide longer life in outdoor applications than other materials such as closed cell neoprene and related blended gasket materials.

Silicone Sponge

Silicone sponge rubber has the combined properties of resilience, high temperature stability and general inertness unavailable in any other closed cell sponge gasketing material. Silicones are generally unaffected by extended exposure to temperature extremes from -100°F to 500°F, and are also unaffected by aging and degradation from sunlight and ozone.
