Wacker Elastosil® R 701/70 Silicone Rubber
Categories:	Polymer; Thermoset; Silicone; Silicone Rubber
Material Notes:	Product description: ELASTOSIL® R 701/70 is a non postcure HCR grade for extrusion and molding applications. Special features: heat- and reversion-stabilized Non-post-cure properties: The differences in the mechanical properties of postcured and non-post-cured vulcanizates are only very slight. When Curing Agent E is used, blooming of the decomposition products will not occur. The compounds may be blended to produce any shore hardness value between 40 and 80. Blends with products from other series are also possible. good resistance to mineral oil high elasticity and very low compression set, even when Curing Agent E is used Application: The compounds are recommended for all kinds of seals that come into contact with mineral oils. ELASTOSIL® R 701/70 is used especially when low compression set is crucial for achieving good seal properties. The compounds may also be used for making high quality silicone-rubber-covered rolls.
