A new liquid silicone rubber can be used for the production of automotive gaskets. Molded parts made from ELASTOSIL® RT 728 are reportedly resistant to heat and coolant, and exhibit low compression set even under permanent stress. Car radiators and cooling system components can thus be reliably sealed, injection molded or mechanically dispensed straight onto the part to be sealed.
The elastomer’s high resilience can deliver constant contact pressure and optimum leak-tightness in the seal groove. Moreover, even long-term stress reportedly has very little effect on the overall property profile of the rubber.
