TECNOFLON® FOR 3390 is a medium viscosity cure incorporated fluoroelastomer terpolymer (FKM) with high fluorine content (70 % wt). Tecnoflon® FOR 3390 is designed for applications requiring outstanding fuel and chemical resistance.
Some of the basic properties of Tecnoflon® FOR 3390 are:
- Good scorch safety
- Reduced mold fouling
- Excellent mold release
- Excellent resistance to fuels
- Very good heat resistance
- Very good compression set
TECNOFLON® FOR 3390 can be used for compression, injection and transfer moulding of shaft seals, valve stem seals, gaskets or any item requiring excellent chemical resistance. This material can be combined with the cure system and other typical fluoroelastomers compounding ingredients. Mixing can be accomplished with two-roll mills or internal mixers.
TECNOFLON® FOR 3390 can be extruded into hoses or profiles and can be calendered to make sheet stocks or belting. Finished goods can be produced by a variety of rubber processing methods.
