Fish tank dam liners price geomembrane in China
Plastic membrane used in anti-seepage projects at home and abroad mainly applied in tunnel, which are all polymer chemistry flexible material with small rate, strong extension, high deformity, corrosion resistance, low temperature resistance and good ability of antifreezing. Its main mechanism is separating leakage channel of earth dam with the waterproof feature of plastic membrane, bearing water pressure and adapting deformation of dam with large tensile strength and elongation; While non-woven geotextile is a polymer short-fiber chemical material, and it is formed through needle-puncturing or thermal pasting. and it has higher tensile strength and elongation.
Product Features:
Geomembrane is a waterproof separating material taking high macro-molecular polymer as basic raw material. It is mainly divided into LDPE geomembrane, HDPE geomembrane and EVA geomembrane.
1. Width, thickness and specification are complete;
