Rubber & Tire Additives
A large number of natural and synthetic rubbers such as NR, BR, SBR, NBR, EPDM, CR, and VMQ need additional reinforcing fillers to achieve the desired properties for the final product.
The primary rubber reinforcing fillers are carbon blacks ("black" fillers) and precipitated amorphous silicas ("white" fillers). Reinforcing "white" fillers such as Grace's® PERKASIL® precipitated silicas are effective in rubber formulations to add tear strength, abrasion resistance, and aging resistance to rubber products.
