Tecnoflon® FOR TF 838K is a medium viscosity cure incorporated fluoroelastomer terpolymer (FKM) with 68% fluorine content. Tecnoflon® FOR TF 838K is designed to improve bonding in any application requiring adhesion to metal. In shaft seals or valve stem seals production, Tecnoflon® FOR TF 838K greatly reduces the reject rate due to adhesion and molding problems. Tecnoflon® FOR TF 838K shows low crosslinking density, in order to allow further addition of curatives. 
Some of the basic properties of Tecnoflon® FOR TF 838K are: 
- Superior bonding to metal 
- Very good scorch safety 
- Outstanding processability 
- Lack of mold fouling 
- Excellent hot tear resistance 
- Excellent mold release
Tecnoflon® FOR TF 838K can be used for compression, injection and transfer molding of shaft seals, valve stem seals, O-rings, gaskets and seals. Tecnoflon® FOR TF 838K 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 TF 838K 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.
