1. Nature
This product adopts strict screening of tires, all using semi-steel tires as raw materials, after pyrolysis, coke slag coarse powder, iron removal, secondary crushing, secondary iron removal, modification, granulation, sieving, drying and cooling, The finished modified particle pyrolysis carbon black is obtained. The carbon black is in the form of granules, which has the advantages of fast eating, low powder rate, less dust flying, convenient transportation and use, small product particle size, large specific surface area, high hardness, high tensile stress, low heat generation, flex resistance, It is an environmentally friendly product with features such as aging resistance and good processing performance.
2. Function
This product can be filled in a large amount of rubber, can give the rubber a higher tensile stress and tear resistance, can improve the processing performance of the rubber, and the granular carbon black can shorten the mixing time, reduce the energy consumption of the mixing, and improve the product Dimensional stability, reduce compression permanent denaturation, increase the adhesion of rubber and other materials, and improve the appearance and quality of products.
3. Usage
This product is suitable for natural rubber, styrene butadiene rubber, butyl rubber, butadiene rubber, chloroprene rubber and other rubber products. It can fully or partially replace carbon blacks such as N770, N990, and partially replace carbon blacks such as N220, N330, N550, and N660. . It is widely used in the manufacture of various tires such as carcass, tread, cord, apex, oil skin, inner tube, cushion belt, bicycle tire, bicycle tire, motorcycle tire, rubber shoes, hose, V-belt, tape, sealing rubber and other rubber products . Especially used in the inner liner of tires, it can be filled in large quantities, can effectively prevent the intrusion of air, and improve the airtight performance of the product.
4. Package and Storage
