Comprehensive Insights into EPDM Rubber
EPDM rubber, or ethylene propylene diene monomer rubber, is a synthetic rubber prized for its exceptional resistance to weathering, ozone, and UV radiation. Its ability to withstand extreme temperatures, from -50°C to 150°C, and its chemical resistance make it ideal for outdoor applications. Common uses include automotive seals, construction membranes, and electrical insulation. The production process involves polymerization of ethylene, propylene, and a diene monomer, followed by stripping, recovery, and shaping.
The cost of EPDM rubber is multifaceted. Raw material prices (ethylene, propylene, and diene monomers) fluctuate significantly, directly impacting the final cost. Energy costs play a crucial role, with fluctuations in electricity and natural gas prices affecting production expenses. Manufacturing process efficiency also influences costs. High demand, especially from sectors like automotive and construction, can drive prices up. Finally, market competition plays a significant role in price determination.
