Coupsil® VP 6508

Technical Datasheet | Supplied by Evonik
Coupsil® VP 6508 by Evonik acts as a reinforcing filler. Designed for peroxide-cured rubber compounds where optimum technical properties are required. Imparts greater tensile strength, higher modulus, optimized dynamic properties, lower compression set values and better abrasion resistance. It reacts with unsaturated polymers during vulcanization under the formation of covalent chemical bonds. Offers homogeneous modification with low moisture adsorption during storage and significantly lowers development of ethanol during mixing and processing. It is a reaction product of organosilane Dynasylan® VTEO [vinyltriethoxysilane] with 8 parts and Ultrasil® VN 2 with 100 parts. Coupsil® VP 6508 has a shelf life of 24 months.
