Fluorine content（%）：66%
Appearance：Form white or light odorless translucent film.
Scope of application: Suitable for making various sealing rings, gaskets, oil seals, leather bowls, O-rings, extruded tape, extruded hose, shockproof gaskets and so on.
Product features: It has excellent wide temperature resistance, chemical resistance and good mechanical properties.
Applications:Fluorine rubber is mainly used in high and low temperature sealing, vacuum instrument equipment, chemical equipment, automobile, aviation and other fields.
Raw gum with high Mooney viscosity（121~140 ）：Excellent tensile strength, low compression permanent deformation, good release property, good bonding with metal, suitable for the production of molded O-rings, gaskets, oil seals, etc.
Raw gum with Medium Mooney viscosity（60~80）：Wide molecular weight distribution, good heat resistance, improved processing performance, good fluidity, good adhesion with metal, suitable for O-ring, oil seal, complex structure miscellaneous parts, rubber plate and so on.
Raw gum with low Mooney viscosity（20~39）：Good fluidity, suitable for extruding hose, sealing and other extruded products.
