Physical and chemical properties of the product with similar, but slightly lower nitrogen adsorption specific surface area. Slightly higher absorption value for granular products, the toluene extract is less than. This product has ultrapure products. This product is mainly used as filler for rubber and plastics, can also be used in the metallurgical industry as raw materials or high-temperature tungsten carbide products, insulation material, reducing agent and so on. In the rubber compound with a large number of the goods, does not affect the adhesion compound, when the match reached phr, like leather, rubber products available. It keeps the plastic material is easily processed, does not affect the curing. The hardness of vulcanized rubber is small, low heat, small deformation, scratch-resistant curved, anti-aging performance.
