Rubber used

Silica for rubber and tire industries

STANDARD: HG/T 3061-2009

CAS NO: 112926-00-8(7631-86-9)

EINECS No: 231-545-4

Product Description: HCP 180 can be used in sole as reinforcing filler. Its reinforcing performance is close to carbon black. It can empower rubber products with light color and transparency.

HCP120 and HCP160 has high wear resistance and high reinforcing performance. It can be used in tire to improve the cohesiveness of steel wire, cord thread and sizing material, to reduce the rolling resistance of tire, and to improve the wear resistance and security of tire.
