Neoprene synthetic rubber

Neoprene is a synthetic rubber known for its versatility and resilience. This chloroprene-based elastomer exhibits exceptional resistance to various environmental factors, including ozone, sunlight, and weathering. Neoprene maintains its flexibility across a wide temperature range and boasts excellent chemical stability, making it resistant to degradation from oils, acids, and other substances. Notably, neoprene is prized for its remarkable resistance to water and its ability to remain buoyant, even in aquatic environments.

Commonly used in the production of wetsuits, gloves, and other protective gear, neoprene provides insulation against cold temperatures. Its robust and durable nature extends its applications to gaskets, seals, hoses, and automotive components, where its elasticity and resistance to abrasion and tearing are highly valued.
