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.
