Anti-abrasive Agent , Si - 69 - 50GR , Yellow granule , Used In Soles And Tires​.


Recommendations and Applications:


Silane coupling agent Si-69 is successfully and widely used in rubber industry. 


It improved the vulcanizates’  performance in tensile strength , tear strength , 


abrasion resistance , anti vulcanization reversion and compression set , as well as decrease 


compound’s viscosity and increase processing safety. 


Si-69 is especially applicable for rubber compound using silica and silicate as filler ,


such as silica , talc powder , mica powder , clay , etc. 


It is applicable to polymers including NR , SBR , BR , NBR , EPDM , IR , etc. 


Mainly used in manufacturing tires, soles, roller, seals, and other rubber products.
