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.
The products in the ELASTOSIL® R plus series combine the advantages of solid silicone rubber with those of addition-curing liquid silicone rubber, namely outstanding mechanical properties combined with high productivity. ELASTOSIL® R plus grades are available as 1-part and 2-part systems.
Applications
Heat-curing silicone rubber is used in a diverse range of applications across all kinds of industries:
- Automotive and aerospace
- Electrical engineering
- Transmission and distribution cables (T&D)
- Construction
- Mechanical and plant engineering
- Consumer goods and the food industry
- Health care and medical technology
Under the SILMIX® brand, we also develop, compound and produce customized, ready-to-use silicone rubber compounds for you – at various locations around the world, and to the same high WACKER quality standard.
