  • SiSiB® PC2000 in SiSiB® PC2000B reacts with silanol groups of white fillers during mixing and with the silicone polymer during vulcanization under the formation of covalent chemical bonds. This imparts greater tensile strength, higher moduli, reduced compressionset, increased abrasion resistance and optimized dynamic properties.

  • SiSiB® PC2000B is used in a variety of rubber products where silanol group-containing white silicone fillers are used and where optimum technical properties are required.

Packing and Storage

  • SiSiB® PC2000B is supplied in net weight 25Kg HDPE lined paper sack.

  • When stored between 10°C and 40°C in the original unopened original container SiSiB® PC2000B has a shelf life of one year in a dry place.
