Anti-abrasive Agent , SI-50 , Yellow granule , Used for soles and other rubber products.
Recommendations and Applications:
Silane coupling agent Si-50 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-50 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.
