Wide high elasticity, waterproofing membrane impermeable rubber modified sulfur-free high-performance features liner EPDM membrane system is a highly flexible, high weathering in the open air environment, resistant to adverse weather conditions, and have reflected numerous excellent performance. 1, high elasticity: Tak Cheung rubber membrane at minus 50 degrees still maintain good flexibility, so in all weather conditions and terrain conditions can be year round construction. 2, high elongation: DS Cheung rubber membrane elongation over 350% scalable and with the base surface of the shaped parts fit and stretch elongation to prevent extension of cracking phenomenon. 3, anti-static pressure Puncture resistance: with other materials, a more excellent resistance to hydrostatic puncture resistance, and high air tightness. 4, excellent weather resistance: can not be compared with other products anti-UV and ozone resistance, acid and alkali resistance, useful life over 30 years. 5, Shi soil convenient: This product minimum width of 1.6 meters and 1.8 meters to 20 meters, can be field welded junction, and in accordance with the specifications for precast molding, reducing binder costs, and adhesives toxic pollution, heat welding junction adhesion strength can not be compared. 6, low maintenance, high environmental protection: After installation is complete, almost no routine maintenance, the product meets food grade quality standards, use in other areas can not be contested. 7, to meet the requirements of various regulatory standards: in line with national standards and other international standards, industry standards, national requirements for food standards, soil, biological, animal, water and harmless. Mainly due to its being widely recognized durability unique physical properties, versatility, wide range of purposes, and wide coil brings easy installation, and the installation of low-cost, to eliminate the use of toxic pollution problems binder . Uses: irrigation canals, scenic pond, seepage, aquaculture, water impermeable, and prevent water close to the soil, fermentation deterioration, road, airport runways, subway, underground dibble body of water penetration, sealing animal waste, waste disposal sites , artificial snow tanks, artificial natural water tanks, fire tanks, sewage treatment pond, flood protection embankments penetration, grain storage moisture, water and cover, industrial products packaging moisture, shock, building houses, blocking sound, waterproof, thermal insulation, family bathroom, Chufang high impermeable waterproof, waterproof salt production salt ponds.
