Vulcanized rubber – Technical characteristics
Vulcanized rubber is formed by mixing raw rubber (elastomer, amorphous polymer) with different components to form a combination, then vulcanized to form rubber. Vulcanized rubber will look like a sponge but completely sponge foams do not acquire those technical characteristics. It is high heat resistance, anti-aging, ozone resistance, heat insulation, fuel oil resistance, Iubes resistance, […]
Vulcanized rubber is formed by mixing raw rubber (elastomer, amorphous polymer) with different components to form a combination, then vulcanized to form rubber.
Vulcanized rubber will look like a sponge but completely sponge foams do not acquire those technical characteristics. It is high heat resistance, anti-aging, ozone resistance, heat insulation, fuel oil resistance, Iubes resistance, odor-free, high compression resistance for both static and copper forces. Has extremely good sound and heat insulation. Vulcanized rubber can withstand temperatures in the range from -60 to + 200 degrees Celsius, a maximum of -70 to + 260 degrees Celsius.
