WACKER offers two types of solid silicone rubber: ELASTOSIL® R (peroxide-curing grades) and ELASTOSIL® R plus (platinum-catalyzed, addition-curing grades). You may choose between base stock and ready-to-use mixtures. Crosslinkers, stabilizers, pigments and other additives round out our product offering.
ELASTOSIL® R solid silicone rubber grades are peroxide-curing. They can be processed by conventional methods, such as extrusion, calendering, compression and transfer molding, or injection molding. They cure in heat and are ideal for manufacturing a variety of silicone rubber articles.
This product can be used within a temperature range of – 55 °C to + 210 °C. The addition of heat stabilizers at service temperatures of more than 180 °C is recommended. Further information to improve the heat stability by use of specific ELASTOSIL® AUX Heat Stabilizers can be obtained from the Technical Information Sheet “ELASTOSIL® AUX Stabilizers H” or from the latest brochures.
