Tecnoflon® PL 557 is a new generation low temperature peroxide curable fluoroelastomer with 65.5% wt fluorine content. Tecnoflon® PL 557 exhibits excellent low temperature flexibility (TR10 = –29°C), close to Tecnoflon® PL 455, but with improved chemical resistance and permeability. Like all other Tecnoflon® peroxide curable grades, it exhibits excellent processability; moreover it needs very short post-curing cycles.
Some of the basic properties of Tecnoflon® PL 557 are:
- Excellent low temperature flexibility
- Low post cure
- Superior mold flow
- Lack of mold fouling
- Excellent mold release
Tecnoflon® PL 557 can be used for injection, injectioncompression and transfer molding of O-rings, gaskets and seals. Tecnoflon® PL 557 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® PL 557 can be extruded into hoses or profiles and can be calendered to make sheet stocks or belting.
