Great
1. Nature
This product is strictly screened for tires, all steel tires are used 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 high feed speed, 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 N660, N770, N990 and other carbon blacks, and partly replace N220, N330, N550, etc. 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 invasion of air, and improve the airtight performance of the product.
4. Package and Storage
Packaging: The outer is plastic woven bag, and the inner is PE bag.
Weight: The net weight is 25±0.25kg. It can also be packaged in a space bag according to user’s requirements, and the weight is determined by user’s requirements.
Storage: Store in a dry, cool and ventilated indoor space. Pay attention to fire and moisture.
