Product information :PET series polymer polyester composite waterproof coil is fully studied on the basis of existing waterproof materials, according to the new requirements of modern waterproof engineering developed, the product technical performance indicators in line with the "polymer waterproof material part - sheet" product selection of PET as the waterproof layer, the top and bottom of the polyethylene layer, The double-sided composite non-woven fabric is a new structural waterproof material made of reinforced layer. The product creatively uses PET material, which is 9 times greater than the tensile strength of polyethylene, as the main waterproof layer of the waterproof coil, so it has excellent physical and mechanical properties, and significantly improves the fracture tensile strength and thermal aging retention rate. PET is one hundred times smaller than polyethylene O2 and CO2, which enhances the function of composite waterproof coil and expands the scope of product use. PET itself has strong UV resistance and high temperature resistance, and additives are added to form double protection and extend the service life of sheet. The product is made of synthetic polymer material and processed into waterproof coil, which belongs to green environment-friendly building materials. When constructing the product, there is no special requirement for the moisture content of the screed layer (base), as long as there is no open water, the construction can be carried out, and the quality of the project is reliable. 1. Waterproofing of ordinary roofing, water storage surface and planting roofing of industrial and civil buildings; 2, underground waterproof; 3, moisture-proof, steam insulation; 4. Waterproof toilet bath room; 5, pool, channel seepage prevention; 6. Tunnels, Bridges and culverts; 7. Anti-pollution works such as garbage disposal sites and chemical harmful storage sites.
