Product Description

Description: GreenThinking^®PF82 is an insulating nano reinforcing agent with hydroxyl removal and surface activation treatment, which is refined by processing selected non-conductive high-whiteness natural composite mineral raw materials, retaining raw materials through special processing technology and strict internal quality control process, so that the products have uniform chemical purity and stable particle size distribution. Most of the particle sizes are distributed in the nanometer level, the porosity is large, the impurity is less, and the surface is activated. As a reinforcing functional filler in the rubber and plastic industry, it has outstanding advantages such as good insulation, good dispersion, high reinforcement and high whiteness, and is widely used in rubber and plastic industries.


Applications:
        PF82 can offer good reinforcing effect, slightly stronger as carbon black N550 so that it is
wildly used in mechanical rubber goods which are required to improve wear and oil
resistance and thermal aging performance.
       PF82 can offer excellent insulation and low compression set so that it is wild used in electronic
parts.
       PF82 has high whiteness so that it is wildly used in light color products.
       PF82 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.
     Improved wear resistance, oil resistance, and thermal aging properties.
     Good air tightness and smooth extruded product.

Test Conclusion:
1.GreenThinking ® PF82 is a non-conductive material with clean and special structure, and its experimental insulation performance is very outstanding.
2.Green Thinking ® PF82 has relatively better comprehensive performance in terms of initial performance (strength, elongation) and comprehensive performance after aging.
3.The whiteness of Green Thinking ® PF82 is very high, the light-colored products produced are good, the rubber dispersion is good, the products are relatively stable, and the surface of the test piece is smooth.

Common usage instruction: PF82 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.
