Butyl rubber
(GB-CK90 is recommended)

GB-CK90 calcined kaolin is a super high purity aluminium silicate suitable for Butyl rubber applications. Featuring high purity, large specific surface area, low loose loading density , anti high temperature , anti-oxidation , violet light shield, excellent electric conductibility, excellent chemical resistance, and very little metal diffusion, constant brightness and HUB performances,GB-CK90 exhibits erosion-proof even in extreme working conditions as in strong acid and alkaline solution. It can significantly enhance the strength of product if it been used in Butyl rubber. Besides, GB-CK90 is available in other rubber and outdoor paint application due to its high brightness, excellent opacity and low residue.
