Tecnoflon® P 549L is a low viscosity, high fluorine (70%), peroxide curable fluoroelastomer. Tecnoflon® P 549L exhibits superior resistance to a wide variety of chemicals, coupled with excellent processability. Tecnoflon® P 549L can be cross-linked using organic peroxides in conjunction with a co-agent. 
Some of the basic properties of Tecnoflon® P 549L 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 
Tecnoflon® P 549L 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 549L 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 549L 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.
