Product Description
TECNOFLON® FOR 421/U is a low viscosity cure incorporated fluoroelastomer copolymer. This grade is well suited for applications where superior flow, mold release, and excellent compression set are required. Tecnoflon® FOR 421/U can be compounded to meet the major fluoroelastomer specifications.

Some of the basic properties of Tecnoflon® FOR 421/U are:
  • Very fast cure rate
  • Very good scorch safety
  • Superior mold flow
  • Excellent mold release
  • Lack of mold fouling
  • Excellent compression set
  • Good extrusion

TECNOFLON® FOR 421/U can be used for injection and transfer moulding of O-rings, gaskets, and seals. The product can be mixed using typical fluoroelastomers compounding ingredients and mixing can be accomplished with two-roll mills or internal mixers.
The 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.
