Wacker Elastosil® R 780/80 Silicone Rubber
Categories:	Polymer; Thermoset; Silicone; Silicone Rubber
Material Notes:	ELASTOSIL® R 780/80 silicone rubber contains large amounts of inert fillers (mainly ground quartz) and has been developed specifically for blending with low durometer bases. Application: ELASTOSIL® R 780/80 silicone rubber allows large amounts of inert fillers to be readily incorporated into silicone rubber bases. This avoids the risk of silicosis when inert fillers are compounded on a roll mill. The main advantages of blends containing inert fillers are, for example, their improved oil resistance and grindability. It can be used to rapidly adjust the specific gravity of formulations to meet specifications. Blends with low durometer bases result in compounds of medium Shore A hardness with high filler content and good mechanical properties. Information provided by Wacker Chemie AG.
