Precipitated Silica(White Carbon Black)– Reinforcing Agent for Tire Tread & Industrial Rubber Goods
- Overview
- Recommended Products
Product Name: Silica/ White Carbon Black
Product Details:
1.Chemical Formula:SiO2.nH2O
2.Appearance: White particle、White powder
3.Specification: Common, High- Reinforcing, Hyperfine
4.Standard: HG/T3061~3073—1999
5.Products Description: Widely used in making Synthetic sole or rubber shoe, rubber conveyer, belt, rubber roller, and damp unit rubber product.
6.Applications and Characteristics：This material processes well with rubber. It also absorbs and disperses easily when mixed. As a rubber reinforcing filler, it has good mechanical energy and can improve the property of the rubber product in elongation and abrasion resistance. When used with carbon black, it can ameliorate the processing property, as well as the static and dynamic property. With the dry powder fire extinguisher, it presents a fine adsorption capacity and flowability, functioning well in preventing caking.
7.Package: PP outer bag with film and PTFE inner bag,net weight 15kg 20kg, or packing according to customer.
