Specification Grade: 66% Fluorine copolymers formulated for the ultimate in compression resistance. SP compounds are the best choice for O-rings.

Low Cost: 66% Fluorine copolymers formulated for low cost. LC compounds are used in lathe cut and custom molded goods, including valve stem seals.

Low Cost - Low Viscosity: 66% Fluorine copolymers formulated for low cost. LC-LV compounds are also injection moldable.

Low Cost - Thick Cross-section: 66% Fluorine copolymers formulated for low cost. LC-THK compounds are fissure resistant in thick cross-sections; these compounds also exhibit enhanced rubber-to-metal bonding.

General Purpose: 66% Fluorine copolymers formulated for molding complex geometric shapes. GP compounds exhibit improved hot tear resistant properties and offer a variety of colors.

General Purpose - Low Viscosity: 66% Fluorine copolymers formulated for injection molding. GP-LV compounds also exhibit the improved hot tear resistance of their higher viscosity counterparts.

Intermediate Fluorine: 68% Fluorine terpolymers formulated for improved chemical resistance. IF compounds are good choices for fuel applications.

High Fluorine: 70% Fluorine terpolymers formulated for much improved chemical resistance. HF compounds are excellent choices for fuel applications, including methanol-containing fuels.

High Fluorine - Low Temperature: High fluorine tetrapolymers formulated for low temperature flexibility. HFLT compounds are excellent choices for fuel applications, including methanol-containing fuels, where low temperature flexibility is also essensial.

FDA - approved for food contact: 66% Fluorine copolymers formulated with compounding ingredients approved for food contact (U.S. FDA 21 CFR 177.2600(c)(4)(1) listed). FDA compounds are available in a variety of colors.

Specialty Compounds:   This family includes low shrinkage, non-post cure, high temperature and dynamic vulcanized fluorocarbon elastomer compounds.

TFEP: 55% Fluorine copolymers of tetraflourethylene and propylene. TFEP compounds exhibit outstanding resistance to hot water, steam, acids and alkalis; these compounds also give superior performance in amines and phosphate esters as compared to conventional fluoroelastomers.
