Product Details
COUPSIL® VP 6508
Precipitated silica, surface-modified with organosilane DYNASYLAN® VTEO for application in the rubber industry.
Scope of Application
COUPSIL® VP 6508 is used as a reinforcing filler in rubber compounds. It reacts with unsaturated polymers during vulcanization under formation of covalent chemical bonds. This imparts greater tensile strength, higher moduli, reduced compression set, increased abrasion resistance and optimized dynamic properties. COUPSIL® VP 6508 is used in peroxide-cured rubber compounds in combination with white fillers and where optimum technical properties are required. Application fields are: Mechanical rubber goods
