Fluoroelastomers / VITON® Rubber

Fluoroelastomers are copolymers in a family of synthetic rubber compounds, which, when first introduced, consisted of hexafluoropropylene and vinylidene. Today, the consistency of Fluoroelastomers has been modified to provide even greater thermal stability and solvent resistance. This synthetic rubber compound offers premium, long-lasting reliability in even the harshest environments.

King-rubber Fluoroelastomers are resistant to chemicals, oil, and heat. Our Fluoroelastomers are used for numerous high-performance applications in the aerospace, automotive, industrial fields, and more. Fluoroelastomers are custom molded into a wide variety of rubber products including seals, o-rings, rubber gaskets, valves, and rubber diaphragms.

Viton® is a registered trademark of Dupont Dow Elastomers L.L.C. Viton® is used in a class of synthetic rubber fluorocarbon elastomers. A copolymer is chosen for the Viton® rubber compound based on the product application. Polymers commonly used are hexafluoropropylene (HFP) and vinylidene fluoride (VDF or VF2), terpolymers of tetrafluoroethylene (TFE), vinylidene fluoride (VDF) and hexafluoropropylene (HFP), and perfluoromethylvinylether (PMVE).

Pierce-Roberts Viton® provides high temperature stability, low compression set, and resistance to chemicals, oil, and ozone. Although Viton® was initially fabricated for the aerospace industry; this rubber compound is also used in fluid power, automotive, appliance, and chemical applications for rubber products such as hoses, seals, o-rings, expansion joints, shaft seals, and rubber gaskets.

Urethane Rubber

Urethane rubber, also known as spandex, is a polymer containing a urethane block for strength and heat resistance as well as a polyether block for elasticity. As a result, urethane rubber is considered one of the most versatile rubber compounds available. Urethane rubber is resistant to abrasion, powerful impacts, ozone, chemicals, and radiation.

Urethane is an oil-resistant rubber and performs well in oil and fuel applications. Its high resilience and low temperature flexibility make King-rubber high-performance urethane rubber suitable for applications including rubber rollers, belts, rubber diaphragms, o-rings, rubber gaskets, seals, hose tube and covers, vibration isolators, bumpers, impellers, and more.

Silicone

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.

King-rubber’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.

Buna N Rubber

Buna N rubber is a synthetic rubber compound that is also known as standard Nitrile rubber. The compound comprises co-polymers: acrylonitrile and butadiene. Acrylonitrile is a volatile organic liquid. Butadiene is a synthetic chemical compound. When mixed, these two polymers react and produce one of strongest oil-resistant rubber compounds currently available.

Buna N rubber products are resistant to both solvents and oils. Pierce-Roberts molded rubber products that are manufactured with Buna N are appropriate for many industrial applications, including oil hoses, fuel hoses, o-rings, and rubber gaskets. Buna N is similar to Buna S in that it can be vulcanized.
