Product Description
Viton® AL-300 is an "AL-family" gum polymer that demonstrates improved processing when compared to its precursor Viton B-70N. This gum provides:
-Lower viscosity
-Improved mold flow
-Better mold release
-Less mold fouling
-Improved compression set resistance, and
-Good low temperature characteristics

Applications:
-Fuel systems, such as fuel injectors O-rings
-Injection and transfer molding of O-rings, gaskets, and other sealing devices
-Extruded cords, profiles and tubing, or calendered sheets, when a blend of gum polymers are used
-Solution coatings of fabrics and other substrates
