EPDM, TPU and PTFE are three common engineering materials. When used to manufacture Gasket/Seal, each has unique performance and applicable scenarios. Selection suggestions: For hot and cold water systems/outdoor air seals → EPDM For motion seals/oil pressure systems/wear environments → TPU For strong acid and alkali/high temperature and high pressure/high hygiene requirements → PTFE If you need further material selection suggestions or structural diagrams, you can also tell me your application scenario and I can help you make specific recommendations. 1. EPDM Sealing Gasket (Ethylene Propylene Rubber) ✅ Features: Full name: Ethylene Propylene Diene Monomer Strong weather resistance: Very resistant to ozone, UV rays and aging Good temperature resistance: -50℃ to +150℃ (some formulas can withstand up to +180℃) Excellent resistance to water vapor, hot water and cold water Good electrical insulation Corrosion resistance to polar liquids (such as alcohol, ketones) HVAC systems Outdoor equipment seals Food grade water seals (FDA grade formula)
