Wholesale 1.5mm/1.8mm Polymer Roof Reinforced TPO Waterproof Membrane

Product overview:

Description of TPO Waterproof Membrane
TPO waterproof membrane is a thermoplastic polyolefin material that combines the long-term weather resistance and durability of ethylene propylene rubber with the weldability of polypropylene. A polyester fabric layer sandwiched between two layers of TPO material enhances its physical properties, improving tensile strength, fatigue resistance, and puncture resistance. With high reflectivity and no chlorine content, it is environmentally friendly and ensures construction safety.

TPO roof membranes are classified into:
● Type L fiber-backed membrane
● Type H homogeneous membrane
● Type P fabric-reinforced membrane

CHARACTERISTICS / ADVANTAGES:

Description of TPO Membrane Properties

• Crafted via advanced polymerization technology, this product combines ethylene propylene rubber and polypropylene, integrating the superior weather resistance/durability of the former with the weldability of the latter.
• Leveraging special formulation technology, it eliminates the need for plasticizers prone to causing material embrittlement. It offers high flexibility while preventing the embrittlement common in polyolefin materials due to plasticizer migration, ensuring long-term waterproof performance.
• Reinforced with a sandwiched polyester fiber fabric layer, the membrane gains high tensile strength, fatigue resistance, and puncture resistance—ideal for mechanically fixed roof systems.
• Exhibits excellent thermal stability: remains flexible at -40°C and retains mechanical strength under elevated temperatures.
• Chemically inert: resists corrosion from acids, alkalis, salts, animal/vegetable oils, and lubricants, while inhibiting microbial growth (e.g., algae, mold).
• Light-colored (predominantly white) with a smooth, highly reflective surface, delivering energy-saving benefits and pollution resistance.
• Chlorine-free—contains no chlorinated polymers or chlorine gas emissions during welding/use—making it environmentally safe and human-health-friendly.
• High-strength sealing is achieved via hot welding at overlaps, forming a robust bond.

Scope of application:

This product is applicable to waterproofing layers of exposed or non-exposed roofing surfaces in buildings, as well as waterproofing for underground structures prone to deformation. It is particularly suitable for lightweight steel structure roofing and large concrete structure roofing, and is the preferred waterproofing material for large industrial factories and public

buildings and other roofing structures.

Our advantages:

Shandong Shuangyu Waterproof Material Co., Ltd., founded in 2004 in Shouguang, Shandong, has a 5 million yuan capital and a 20,000 sq m area. It owns advanced production lines, making and selling diverse waterproof materials like SBS modified asphalt film, polymer films, and coatings. These are widely used in roofing, infrastructure, and buildings for waterproofing, and also in automobiles and sewage pipes for anti-seepage and other functions.

Packaging and transportation:

When buying a product, considering packaging and transportation is crucial to guarantee its safe and intact arrival. Here are the steps for packaging and transporting waterproofing membranes:

• Packaging: Utilize a roll woven bag with a lifting strap to safeguard during transit.

• Protection: For enhanced safety, customers can opt for wooden crates to prevent damage.

• Label: Mark the package with clear details like product name, shipping address, and handling instructions.

• Transportation: Our professional team will load and a reliable company will transport, with the method depending on quantity, weight, and destination.
