EPDM Rubber Sheet – KXT B400EPDM
Kaxite Sealing, a professional China rubber sheet manufacturer, presents the KXT B400EPDM EPDM Rubber Sheet – a high‑performance, weather‑resistant elastomer sheet engineered for demanding sealing, gasketing, and insulation applications. Made from premium EPDM (Ethylene Propylene Diene Monomer) compound, this commercial‑grade rubber sheet offers exceptional resistance to UV radiation, ozone, weathering, and temperature extremes, making it the material of choice for outdoor, marine, and industrial environments.
Why KXT B400EPDM? Unlike standard rubber materials, EPDM provides outstanding long‑term durability in harsh conditions – it remains flexible at low temperatures (-50°C) and retains its sealing integrity up to +140°C. Its excellent resistance to water, steam, diluted acids, alkalis, and detergents, combined with good mechanical strength and low electrical conductivity, makes it ideal for pipe gaskets, weather stripping, pump seals, and high‑pressure line applications. Commercial‑grade EPDM is less rigid than roofing EPDM, offering better formability for custom gasket fabrication.
As a leading compression sheet supplier in China, Kaxite offers the KXT B400EPDM in a wide range of thicknesses, widths, and roll lengths, with or without fabric or wire reinforcement, and in various hardness grades (40–90 Shore A) to suit your specific application.

Key Features & Performance Benefits
UV & Ozone Stability EPDM is inherently resistant to ozone and UV radiation – it will not crack or become brittle even after years of outdoor exposure, making it ideal for roofing, marine, and automotive exterior applications.
Temperature Extremes With a continuous service range of -50°C to +140°C, EPDM rubber sheets maintain elasticity and sealing force in both arctic cold and high‑temperature process environments.
Water & Steam Resistance EPDM does not hydrolyse or swell in water, making it suitable for fresh water, seawater, and steam applications up to 100°C continuously and higher intermittently.
Chemical Compatibility Good resistance to diluted acids, alkalis, alcohols, ketones, and detergents. (Note: limited resistance to petroleum oils, aromatic hydrocarbons, and strong oxidizing agents.)
Mechanical Strength Tensile strength ≥ 8 MPa and elongation ≥ 250% provide excellent durability, allowing the sheet to conform to irregular surfaces while resisting tears and abrasion.
Low Electrical Conductivity EPDM is a good electrical insulator, suitable for use in electrical enclosures and as insulating mats where low conductivity is required.
Typical Applications
Pipe Gaskets & Flange Seals EPDM sheets are cut into gaskets for pipe flanges, pumps, and valves in water, wastewater, and chemical services where weather resistance is required.
Marine & Underwater Seals Exceptional water resistance makes EPDM ideal for boat hatches, deck fittings, underwater cable seals, and marine equipment gaskets.
Automotive & Transportation Weather stripping, door seals, window trim, radiator hoses, and under‑hood seals exposed to temperature cycling and moisture.
HVAC & Roofing Used as vibration pads, roof flashing, and weather‑proof seals on air conditioning units and rooftop equipment.
Food & Drinking Water FDA‑compliant grades available for gaskets in food processing equipment and drinking water supply systems (WRAS approved on request).
General Industrial Matting, anti‑vibration pads, bumpers, expansion joints, and any application requiring a flexible, weather‑resistant rubber sheet.
