WACKER ELASTOSIL® silicone rubber is extremely resistant to high and low temperatures (-50 °C to +250 °C; specialty grades: -110 °C to +300 °C) with only slight changes in physical properties between -50 °C and +180 °C. The rubber’s other typical properties include its resistance to chemicals and environmental influences, its lack of odor and taste (many grades conform to BfR and FDA regulations), its water-repellent surface, and its high transparency and good processability. Many other properties can be modified with additives.
