Китай хорошее качество EPDM водонепроницаемые материалы для зданий

EPDM waterproofing membrane (abbreviated as EPDM membrane) is made by mixing appropriate amounts of butyl rubber, vulcanizing agent, accelerator, softener, and reinforcing agent into EPDM rubber, and processing it through processes such as mixing, pulling, filtering, and extrusion molding. Due to the absence of double bonds on the main chain in the molecular structure of EPDM rubber, it is less prone to breakage when exposed to ozone, ultraviolet radiation, and humid heat. Therefore, it has excellent weather resistance, aging resistance, high tensile strength, high elongation, strong adaptability to substrate expansion or cracking, value, light weight, and a wide temperature range (can be used for a long time in the range of -40 to+80 ℃). It is an efficient waterproof material. It can also be used for cold construction, with easy operation, reducing environmental pollution, and improving the working conditions of workers. There are sulfurized and non sulfurized types on the market.
