Comparison of application of PVC Roofing memberane and TPO Roofing memberane


TPO Roofing memberane

TPO Roofing memberane is based on polymerizing polypropylene and rubber together using current state of the art polymer production technology. It can be recycled at any stage of use. TPO Roofing memberane also have excellent resistance to the growth of mold and algae, which can reduce solar reflectance, damage energy efficiency and aesthetics. TPO Roofing ROLL IS A NEW TYPE OF WATERPROOF ROLL MADE OF PETROLEUM RESIN, ETHYLENE, ACETIC ACID, ETHYLENE resin AS THE BASE material, adding antioxidant, ANTI-aging agent, SOFTENer, and surface attached with fabric fiber, ALUMINUM film. Another new trend for TPO memberane is for "green roofs" or "roof gardens". 

PVC Roofing memberane is a kind of thermoplastic PVC roll. PVC Roofing memberane is made of polyvinyl chloride resin as the main component, adding plasticizer and modified materials, etc., and is processed by memberane, extrusion, coating and other technological processes. It belongs to polymer material. General PVC memberane is made of polyester fiber fabric as reinforcement, so that the double-sided PVC plastic layer and the polyester reinforcement in the middle are combined into one polymer memberane.




The development trend of building waterproof materials


Building waterproof materials are diversified. No matter which kind of waterproof material will not dominate the market and unify the world, some of the existing advanced waterproof materials in different countries and different waterproof projects can be used separately; Building waterproof is still based on asphalt coil. The oxidized asphalt oil roofing and underground waterproof film show a downward trend, and the modified asphalt waterproof coil has become the dominant waterproof material in many countries. Polymer waterproof coil plays an important role. EPDM, PVC, TPO and other materials have high durability, safety, environmental protection and no pollution, and can even be reused. They are the mainstream of the development of waterproof materials in the future, and the market demand will gradually increase.


The waterproof material in China and technical route should be designed as follows: to develop the high polymer waterproofing materials, waterproof coating, appropriate development efforts to develop sealing material, and notice to develop water stop, integration of waterproof plugging materials of rigid polyurethane foam insulation materials, gradually reduce low-grade material and increase the proportion of all kinds of high-grade material, comprehensively improve the overall level of waterproof materials in China. Solve the corresponding production equipment, supporting raw materials and construction technology problems, reduce the leakage of buildings, ensure the use of waterproof engineering period gradually increased; Standardize the market, improve the management system, as soon as possible to implement waterproof engineering quality guarantee period system.
