TECNOFLON® PL 958 is a new generation low post cure peroxide curable fluoroelastomer. Tecnoflon® PL 958 exhibits both excellent low temperature flexibility (TR10 = -24°C) and an outstanding resistance to a variety of chemicals. As all other Tecnoflon® peroxide curable grades, it exhibits excellent processability; moreover it needs very short post-curing cycles. Tecnoflon® PL 958 is a higher viscosity version of Tecnoflon® PL 458: please refer to Tecnoflon® PL 458 Technical data sheet for data on chemical resistance.
Some of the basic properties of TECNOFLON® PL 958 are:
- Excellent low temperature flexibility
- Low volume swell in methanol-based fuels
Tecnoflon® PL 958 can be used for compression, injection-compression and transfer molding of O-rings, gaskets and seals. Tecnoflon® PL 958 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.
