Tecnoflon® VPL 85730 and VPL 45730 are a brand new generation of very low temperature peroxide curable fluoroelastomer with outstanding low temperature flexibility (TR10 = -30°C). Furthermore, they show an improved chemical resistance if compared to Tecnoflon® PL grades with similar TR10.
Like all other Tecnoflon® peroxide curable grades, they exhibit excellent processability; moreover they need very short post-curing cycles.

Some of the basic properties of Tecnoflon® VPL 85730 and VPL 45730 are:

• Outstanding low temperature flexibility

• Excellent chemical resistance

• Low post cure

• Superior mold flow

• Lack of mold fouling

• Excellent mold release

Tecnoflon® VPL 85730 and VPL 45730 can be used for compression, injection, injection-compression and transfer molding of Orings, gaskets and seals. Tecnoflon® VPL 85730 and VPL 45730 can be combined with the cure system and other typical fluoroelastomer compounding ingredients. Mixing can be accomplished with two-roll mills or internal mixers.
These materials can be extruded into hoses or profiles and can be calendered to make sheet stocks or belting. Finished goods may be produced by a variety of rubber processing methods.
