Tecnoflon® P 959 is a medium viscosity, high fluorine (70%), peroxide curable fluoroelastomer. Tecnoflon® P 959 exhibits superior resistance to a wide variety of chemicals, coupled with excellent processability and optimum compression set. Tecnoflon® P 959 can be cross-linked using organic peroxides in conjunction with a co-agent. 
Some of the basic properties of Tecnoflon® P 959 are: 
- Low post cure 
- Superior mold flow 
- Lack of mold fouling 
- Excellent mold release 
- Good chemical resistance especially in 
  Alcohol containing fuels 
  Fluids containing amine additives 
- FDA compliant 
Tecnoflon® P 959 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 959 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 959 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. Tecnoflon® P 959 is registered in the FDA Inventory of Effective Premarket Notifications for Food Contact Substances. It can be compounded so that the finished gaskets or seals can be used in food processing equipments (see “Food processing compounds” section on pages 10 and 11).
