Description
Description: GreenThinking®PF81A is removing hydroxyl surface activation treatment of nanometer reinforcing
filler, which is from the high whiteness of natural mineral raw material. The strict internal quality control process
makes the product have uniform chemical purity and stability of the particle size distribution. Most of the particle
size distribution is in the nanoscale. Through the surface activation treatment, it has high reinforcement and
whiteness, good dispersion, insulation and resilience etc. It widely used in the rubber and plastic industries.Applications: PF81A can offer good reinforcing effect, slightly stronger than N660 so that it is wildly used in mechanical rubber goods which are required to improve wear and oil resistance and thermal aging performance.
PF81A can offer excellent insulation and low compression set so that it is wild used in electronic parts.
PF81A has high whiteness so that it is wildly used in light color products.
PF81A is the broad-spectrum functional filler, widely used in synthetic rubber, natural rubber, PVC, CPE and other plastics and cellulose resin products, as a functional reinforcement.Key benefits: Good dispersibility in the compound. Good fluidity of compound, dimension stability, easy to extrude.
Low energy consumption during mixing, shorten the curing time.
Lamellar structure and high porosity.
High BET and purity, no hydroxyl group, on-toxic and odorless.
Extend the burning time and shorten the vulcanizing time curing timeTypical properties & Test Formula:Test Data:

Test Conclusion:1. From the comprehensive performance, both the initial (strength, elongation) and aging performance are superior.
2. PF81S has good elasticity, and the compression set is relatively the best.
3. Compound of PF81S has good fluidity. It can also improve the production efficiency, and the surface of the
products is smooth.Common usage instruction: PF81A can Substitute various filling materials (silica, kaolin, light calcium, etc.) in the
rubber. The product dosage is 30~150phr, and generally 8-10phr hardness can be increased by one Shore A hardness.
Packaging: 25 KG/ Bag, 1000 KG/Pallet
