Tecnoflon® FOR 5381 is a low viscosity cure incorporated fluoroelastomer terpolymer (FKM) with 68.5% fluorine content. Tecnoflon® FOR 5381 is well suited for all applications requiring better chemical resistance and/or long term heat resistance compared to fluoroelastomer copolymers. Tecnoflon® FOR 5381 contains proprietary cure system and special process aid providing superior processability for fast cycles and scorch safety. 
Some of the basic properties of Tecnoflon® FOR 5381 are: 
- Very good processability 
- Excellent chemical resistance 
- Low compression set 
- Good heat resistance 
Tecnoflon® FOR 5381 can be used for compression, injection and transfer moulding of shaft seals, valve stem seals, gaskets or any item requiring excellent chemical resistance. Tecnoflon® FOR 5381 can be combined with the cure system and other typical fluoroelastomer compounding ingredients. Mixing can be accomplished with two roll mills or internal mixers. Tecnoflon® FOR 5381 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.
