Application
Chloroprene rubber gaskets are widely known for their excellent resistance to weathering, ozone, oxidation, and abrasion. They also exhibit good resistance to oil, grease, and a range of chemicals, making them ideal for industrial applications with strong mechanical properties including flexibility and durability. Chloroprene rubber can endure harsh environmental conditions and fluctuating temperatures.
