TECNOFLON® P 757 is a medium viscosity, medium fluorine (67%), peroxide curable fluoroelastomer. Tecnoflon® P 757 exhibits superior resistance to a wide variety of chemicals, coupled with excellent processability, optimum compression set and good flexibility at low temperatures. Tecnoflon® P 757 can be cross-linked using organic peroxides in conjunction with a coagent.
Some of the basic properties of TECNOFLON® P 757 are:
- Low post cure
- Superior mold flow
- Lack of mold fouling
- Excellent mold release
- Good chemical resistance
- Good stress relaxation
- Good metal bonding
- Good low temperature performance
Tecnoflon® P 757 can be used for compression, injection and transfer molding of shaft seals, valve seals, O-rings, gaskets or any item requiring superior chemical resistance.
Tecnoflon® P 757 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 may be produced by a variety of rubber processing methods.
