With excellent elasticity, weather resistance, and long service life, our EPDM roofing membrane systems deliver reliable waterproof protection in extreme climates and demanding environments.
We offer four specialized EPDM membrane systems to meet different project requirements:
No Vulcanized (Uncured) EPDM Membrane
Vulcanized EPDM Roofing Membrane
Reinforced EPDM Roofing Membrane
EPDM Pond Liner
All EPDM rubber roofing membrane products from Qingdao Shuangshi are manufactured in compliance with ASTM D4637 standards. As a professional EPDM roofing supplier, we tailor formulations and structures to ensure consistent performance across applications.
1. No Vulcanized (Uncured) EPDM Roof Membrane
This uncured EPDM roof membrane maintains a reactive rubber structure that allows strong heat-welded seams.
Seam Performance: Weldable seams create a continuous waterproof barrier for large-scale projects
Applications: Municipal tunnels, subways, railways, and underground structures
Performance: Excellent tensile strength, chemical resistance, and flexibility
Specifications: Thickness 1.5–2.5 mm; width 3–6 m (customizable)
2. Vulcanized EPDM Roofing Membrane
The vulcanized EPDM rubber roofing membrane is the most common solution for commercial and residential flat roofs.
Durability: Outstanding resistance to UV, ozone, and thermal aging
Service Life: 15–30 years with minimal maintenance
Applications: Commercial buildings, factories, warehouses, and residential flat roofs
Installation: Suitable for adhered, mechanically fastened, or ballasted systems
3. Reinforced EPDM Roofing Membrane
Reinforced with polyester fabric scrim, this EPDM roofing membrane provides enhanced mechanical strength.
Strength: Improved tear resistance and wind uplift performance
Applications: High-wind zones, industrial roofs, and roofs with maintenance foot traffic
Performance: Greater dimensional stability than standard EPDM membranes
4. EPDM Pond Liner (Vulcanized)
The EPDM pond liner is a specialized EPDM rubber roofing membrane adapted for landscaping and water containment.
Puncture Resistance: Resists plant roots and ground movement
Eco-Safe: Non-toxic, fish-safe, and free of plasticizers
Applications: Garden ponds, decorative water features, and landscape waterproofing
