Applications:
Ø PF41 is wildly used in medical stopper to offer good air tightness and reinforcement.
Ø The medical stopper made of PF41 has good resistance to punctureexfoliation and no acute systemic toxicity caused.
Ø PF41 can also reduce the stickiness of rubber stopper aftersterilization.
Key benefits:
Ø Good dispersibility in the compound.
Ø Good fluidity of compound, dimension stability, easy to extrude.
Ø Lamellar structure and high porosity.
Ø High BET and purity, no hydroxyl group, on-toxic and odorless.
Ø Extend the burning time and shorten the vulcanizing time curing time
