Product Description
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.
This material 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.
