Evonik ULTRASIL® 7800 GR Silica
Categories:	Other Engineering Material; Additive/Filler for Polymer
Material Notes:	ULTRASIL® 7800 GR is a precipitated silica for use as a white reinforcing filler in the rubber industry. Properties and applications: ULTRASIL® 7800 GR is a highly dispersible (HD) silica with a high specific surface area. Due to its outstanding dispersion behavior and the high reinforcing potential, ULTRASIL® 7800 GR is best suited in car tire treads with demanding requirements on high dynamic stiffness, high abrasion resistance and hysteresis characteristics at moderate compound viscosity. Additionally this silica is also used in truck tire tread compounds with superior cut & chip resistance as well as MRG and shoe soles compounds. Bifunctional organosilane like Si 69®, Si 75®, Si 266® or Si 363 are required for optimum properties of precipitated silica in compounds. The use of alcohols, amiones like triethanolamine or alkaline accelerators might be necessary in order to achieve optimum in-rubber data. Application fields are: Tires, shoe soles, mechanical rubber goods, all kinds of other high performance rubber applications. CAS No: 112926-00-8 and 7631-86-9 Information provided by Evonik
