Applications:
Ø PF81S can offer good reinforcing effect, slightly stronger than N660 sothat it is wildly used in mechanical rubber goods which are required to improvewear and oil resistance and thermal agingperformance.
Ø PF81S can offer excellent insulation andlow compression set so that it is wild used in electronic parts.
Ø PF81S has high whiteness so that it is wildly used in light colorproducts.
Ø PF81S is the broad-spectrum functional filler, widely used in syntheticrubber, natural rubber, PVC, CPE and other plastics and cellulose resinproducts, as a functional reinforcement.
Key benefits:
Ø Good dispersibility in the compound.
Ø Good fluidity of compound, dimension stability, easy to extrude.
Ø Low energy consumption during mixing, shorten thecuring time.
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
