Product Details

X 75-S®

X 75-S® is a blend of the bifunctional, sulfur-containing organosilane Si 75® and an N 330 type carbon black in the ratio 1:1 by weight. The product is applied in the rubber industry in combination with white fillers containing silanol groups.

Scope of Application

X 75-S® was developed for customers who prefer to handle Si 75® in a solid version. The Si 75® in the X 75-S® reacts with silanol groups of white fillers during mixing and with the polymer during vulcanization under formation of covalent chemical bonds. X 75-S® imparts greater tensile strength, higher moduli, reduced compression set, increased abrasion resistance and optimized dynamic properties. Compared to X 50-S®, a blend with polysulfidic organosilane, X 75-S® has a higher temperature stability and therefore allows higher mixing temperatures. Application fields are: Low rolling resistance tires
