Tecnoflon® P 457 is a low viscosity, medium fluorine (67%), peroxide curable fluoroelastomer. Tecnoflon® P 457 exhibits superior resistance to a wide variety of chemicals, coupled with excellent processability, optimum compression set and good flexibility at low temperatures. Tecnoflon® P 457 can be cross-linked using organic peroxides in conjunction with a coagent. Tecnoflon® P 457 is a lower viscosity version of Tecnoflon® P 757: please refer to Tecnoflon® P 757 Technical Data Sheet for data on chemical resistance. 
Some of the basic properties of Tecnoflon® P 457 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 457 can be used for injection and transfer molding of shaft seals, valve seals, O-rings, gaskets or any item requiring superior chemical resistance. Tecnoflon® P 457 can be combined with the cure system and other typical fluoroelastomer compounding ingredients. Mixing can be accomplished with two roll mills or internal mixers. Tecnoflon® P 457 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.
