Wacker Powersil® XLR® 630 A/B Liquid Rubber
Categories:	Polymer; Thermoset; Silicone; Silicone Rubber
Material Notes:	Product description: POWERSIL® XLR® 630 A/B is an especially low viscous, two-component silicone compound with excellent processing properties. The vulcanized rubber is noted for the good mechanical properties as well as for the excellent dielectrical behaviour. Special features: ready-to-use, two-component system extreme low viscosity as a liquid rubber excellent processing with suitable mixing and dosing equipment very good dielectrical properties high tracking resistance Application: POWERSIL® XLR® 630 A/B is the right choice for economical production of large articles like hollow core insulators with suitable mixing and dosing equipment. Because of its extreme low viscosity the use of a highcost injection moulding equipment is not necessary, but of course possible if wanted. Due to the outstanding electrical properties POWERSIL® XLR® 630 A/B is an insulating material for indoor as well as for outdoor use. Information provided by Wacker Chemie AG.
