It has excellent flexibility, is easier to bend and fit the base surface than HDPE and LDPE geomembranes, especially suitable for the laying of complex terrain and special-shaped structures, with high construction efficiency. It has outstanding low-temperature resistance, will not brittle fracture in the low-temperature environment of alpine regions, and can maintain stable impermeability performance and mechanical strength for a long time. It has excellent bonding performance, can achieve firm bonding with a variety of materials, has high weld strength, and the impermeable system has good integrity, effectively avoiding leakage hazards. It has excellent anti-aging and UV resistance. After adding special anti-aging additives, the service life can reach more than 30 years, and it can be used exposed or buried. In addition, the product also has good puncture resistance and environmental stress crack resistance, and can resist mechanical damage during construction and external impact during use.
The thickness ranges from 0.5mm to 3.0mm, and the commonly used thicknesses in conventional projects are 1.0mm, 1.5mm, 2.0mm; the width ranges from 4m to 9m, and conventional specifications of 6m width are supported. The length can be cut according to engineering needs, and the maximum length of a single roll can reach 100m. The product is divided into three types: smooth surface, single hair surface and double hair surface. The friction coefficient of the hair surface product is ≥0.55, which is suitable for slope anti-slip scenes; the smooth surface product has higher impermeability efficiency and is suitable for flat laying. All specification products comply with relevant industry standards, with tensile strength ≥18MPa, elongation at break ≥600%, and bond strength ≥0.8MPa, meeting the mechanical performance requirements of various projects.
In tunnel projects, it is used as a special waterproof board, suitable for the impermeable lining of subway tunnels, highway tunnels and railway tunnels. It can effectively resist groundwater leakage and protect the safety of tunnel structures. In water conservancy projects in cold regions, it is used for the impermeable treatment of reservoirs, dams, canals and water storage ponds. It can withstand the low temperature and severe cold in winter and avoid material brittle fracture leading to leakage. In construction projects, it is suitable for the waterproof and impermeable of underground engineering of buildings, planted roofs and roof gardens, as well as the moisture-proof treatment of basements and air-raid shelters. In addition, it is widely used in the impermeable lining of landfills, the lining of aquaculture ponds, the impermeability of artificial lakes and rivers, and landscape projects with appearance requirements. Transparent products can be used in special scenes that need to observe the base course.
