Tecnoflon^® FOR TF 838K

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.
