    As a full-scope EPDM manufacturer, Qingdao Shuangshi offers five specialized EPDM membrane models to meet diverse roofing and waterproofing requirements:

    1. EPDM Waterproof Membrane (Vulcanized)

    • Long-Term Durability: Vulcanized EPDM rubber waterproof rolls resist UV radiation, ozone exposure, and temperature extremes from -45°C to 150°C, have chemical stability and long term  weather resistance.

    • Service Life: Designed for 25+ years of stable performance in roofing systems and municipal waterproof field.

    • Applications: Flat and low-slope commercial, industrial, and residential roofs, reservoir and pond liners, windows and facade waterproof flashing etc,.

    • Installation Compatibility: Fully adhered, mechanically fastened,  welding or ballasted systems .

    • Criteria： Meet and exceed the standard of EN 13956 and ASTM 4637 Type I.

    2. Reinforced EPDM Waterproof Membrane

    • Enhanced Strength: Polyester scrim reinforcement significantly improves tensile strength, tear resistance, puncture resistance and wind uplift performance.

    • Applications: High-wind zones, large commercial roofs, and roofs with frequent maintenance traffic, green roofs and underground engineering resistant to plant root penetration.

    • Performance Advantage: Extended durability and puncture resistance compared to non-reinforced(homogenous) EPDM waterproof membranes.

    • Criteria： Meet and exceed the standard of EN 13956 and ASTM 4637 Type II.

    • We also have fleece backed EPDM membrane which meet the ASTM 4637 Type III.  

    3. EPDM Pond Liner/ EPDM geomembrane (Vulcanized)

    • Puncture Resistance: Effectively resists plant root penetration and ground movement .

    • Eco-Safe Composition: Free from plasticizers and toxic additives; safe for fish and aquatic life.

    • Applications: Garden ponds, water features, reservoir, landscaping, and environmental engineering projects.

    • Criteria： Meet and exceed the standard of EN 13361/EN 13362 and ASTM D7465 Type I.

    4. EPDM facade flashing /EPDM facade membrane

    • Super soft rubber membrane: Extremely easy to bend, shape, and detail at complex internal and external corners and pipe penetrations.
    • Both textured : Double-sided texture increases bonding strength. We use a high-quality formula that is compatible with most silicone adhesives and exhibits excellent adhesion.
    • Ultra-thin thickness： Our technology enables the production of 0.75mm ultra-soft.
    • The 0.5mm ultra soft type, we enjoy the same quality as European factories,   but the price is a little high, we are now trying to low down the cost.

    Key Performance Advantages of EPDM Roofing Materials:

    • Eco-Friendly Profile: Low-VOC, recyclable materials support sustainable construction practices.

    • Fire resistance performance: Fire resistance for roofing application can be customized according to client's requirement.

    Technical Specifications:

    • Thickness: 0.75mm, 0.8mm, 1.0mm,1.2 mm, 1.5 mm, 2.0 mm, 2.5 mm (customizable)

    • Width: 1m–7.5m  (EPDM facade membrane up to 1.4m)

    • Tensile Strength:  ≥ 9.0 MPa (non-reinforced & reinforced);

     the EPDM facade membrane ≥ 8.0 MPa.

    • Elongation at Break: ≥ 300%

    • Roll Length: 15m-30m(50’ or 100’ US standard)  (customizable)

    • Packaging: Folded or rolled for efficient shipping, OEM, Private Label Production.
