氟橡胶GF-300

Chemours Viton® GF-300 Fluoroelastomer (FKM)
Material Notes:  Gum polymer (curative not incorporated). Excellent mold release, lower viscosity version of GF

Temperature of Retraction (TR-10): -6°C. Polymer Fluorine Content: 69.5%. Volume Increase After 7 Days/Methanol/23°C: 5 to 10%

Applications: Injection, transfer, or compression molded goods requiring best fluids resistance.

Viton Type F Information: Comprised of vinylidene fluoride (VF2), hexafluoroproylene (HFP) and tetrafluoroethylene (TFE). Highest fluorine content of Viton standard grades leads to highest chemical resistance and lowest flexibility at low temperatures.
