Manufacturer of Custom Rubber Molded Products
Pierce-Roberts Rubber Co.


Silicone rubber is an inorganic polymer comprising silicone and oxygen. Silicone rubber compounds can be modified through additives including fluorine, phenyl, and vinyl. Fluorine can induce the physical properties inherent in standard silicone and can resist solvents such as fuels. Phenyl improves low temperature flexibility and resists gamma radiation. Vinyl improves the vulcanization qualities as well as the compression set.

Pierce-Roberts's silicone rubber resists ozone, extreme environmental conditions, radiation, moisture, and chemicals, and can retain structural integrity after the compression set. Additionally, some silicone rubber compounds are flame retardant. Typical custom silicone rubber products include insulators, rubber diaphragms, and impact absorbers. A long service life makes this rubber compound ideal for many industrial applications.
