1. EPDM vulcanizado y no vulcanizado de Shuangshi: ¿cuál es la diferencia entre la membrana de EPDM vulcanizada y la membrana de EPDM no vulcanizada?

Ethylene propylene diene terpolymer(EPDM) is compounded from rubber polymer and is often referred t as rubber roof. 1. Shuangshi Vulcanized(or cured) EPDM rubber roofing Chlorination modifies the molecular structure of EPDM rubber by introducing stable chemical bonds, significantly enhancing its performance characteristics as follows. Improved Weather Resistance – Superior UV, ozone, and oxidation resistance, as well as moisture properties. Enhanced Mechanical Strength – Tensile strength increases up to 300% compared to non-chlorinated EPDM. Long-Term Stability – Maintains durability under extreme environmental conditions. Primary Applications: Roofing Membranes & RV Roofing – Widely used in flat roofs, commercial roofing, RV roofing due to its long lifespan and resistance to weathering. Pond Liners – Preferred for applications requiring high durability and chemical stability. 2. Shuangshi Non-Vulcanizd(or uncured) EPDM rubber roofing Non-chlorinated EPDM retains a more flexible molecular structure, offering distinct advantages: Thermal Bonding Capability – Exhibits superior heat-welding performance, making it ideal for seams and flashing in roofing systems. Stability Through Vulcanization – When exposed to high temperatures (e.g., during installation), its chemical structure stabilizes, improving long-term performance. Primary Applications: Roofing Flashings & Details – Used in critical sealing areas where heat welding is required. Large-Scale Civil Engineering Projects – Commonly applied in tunnel linings, subway systems, and other infrastructure due to its excellent thermal adhesion properties. Key Comparison Summary Property Vulcanized EPDM rubber Non-Vulcanized EPDM rubber Weather Resistance Excellent (UV, ozone, oxidation) Moderate (improves with heating) Tensile Strength Up to 300% higher Standard strength Thermal Bonding Limited Superior (ideal for welding) Primary Use Cases Flat roofs, pond liners, automotive Roof flashings, tunnels, subways We can produce both the Vulcanized and Non vulcanized EPDM roofing membrane.

2. Shuangshi EPDM reforzado y no reforzado-----¿Cómo elegir un techo de EPDM de una sola capa, la membrana de EPDM reforzada o no reforzada?

Our Single-ply EPDM roofing membranes are available in two primary variants: reinforced and non-reinforced(normal) EPDM roofing. The fundamental difference lies in the incorporation of a polyester scrim/fabric during the manufacturing process of reinforced EPDM rubber. This polyester scrim/fabric, embedded within the rubber matrix, significantly enhances the membrane's tensile strength and dimensional stability. The Need for Reinforced EPDM EPDM sheets naturally exhibit thermal expansion and contraction properties. While this flexibility is advantageous, it can lead to long-term stress fatigue in non-reinforced membranes. The polyester reinforcement serves several critical functions: Provides structural support to resist stretching forces Maintains dimensional stability across temperature fluctuations Reduces the risk of stress cracking over time Improves resistance to wind uplift forces Reinforced EPDM rubber roofing Applications: Large commercial roofing systems (particularly those exceeding 10,000 sq.ft.) Roofs subject to significant thermal movement (e.g., over metal decks or in extreme climates) High-wind regions (meeting UL 1897 wind uplift requirements) Mechanically attached roof systems Roofs with potential foot traffic or equipment maintenance needs Cost Considerations The reinforced membrane typically carries a 15-30% price premium over non-reinforced options due to: Additional material costs (polyester scrim) More complex manufacturing process Higher performance specifications However, this additional cost is frequently justified by: Extended service life Reduced maintenance requirements Better performance in demanding conditions

EPDM rubber roofings offer four primary installation methods, each with distinct advantages for different project requirements, for all those kind of rubber roofing membranes, our factory can produce according to clients' requirements: Ballasted System EPDM membrane The smooth EPDM membrane is loosely laid over the substrate and secured with rounded river stones (typically 1-2.5" diameter) at 10-15 lbs/sq.ft. This cost-effective method is ideal for large, flat roofs with adequate structural capacity. The stone ballast protects against UV degradation and wind uplift while allowing natural membrane movement. 2.Fully Adhered EPDM membrane Our Fully Adhered EPDM Membrane is produced with a butyl rubber adhesive layer and a protective film.The butyl rubber ensures excellent adhesion to substrates, which provides superior wind resistance and is preferred for steep slopes (up to 4:12) or roofs with penetrations. Clean substrate with no moisture and adhesive selection are critical for long-term performance. 3.Butyl Tape Seaming EPDM membrane Specially formulated butyl tapes create watertight seals at membrane overlaps. This cold-applied method offers quick installation without VOC emissions, making it suitable for occupied buildings or temperature-sensitive projects. Surface cleaning and primer application ensure optimal bond strength. 4.Hot Air Welding EPDM membrane Professional welding equipment heats the membrane edges to 500-600°F（260–316°C）， fusing them into a permanent seam. This creates the strong possible bond for EPDM seams, Shuangshi EPDM roof membrane have superior bonding performance when using the hot air welding method. Meanwhile, skilled technicians and proper quality control measures is also important for the welding waterproof system. To use which method depends on our contractors' roof design, climate conditions, budget, and performance requirements. All methods, when properly executed, can maintain 30+ years of service life.
