Product Details

Geomembrane/waterproof sheet (HDPE,LDPE,EVA,ECB)

★Product introduction:

Geomembrane/waterproof board is a waterproof and impermeable material made of synthetic resin (HDPE, LDPE, EVA, ECB) as the base material, adding antioxidants, ultraviolet absorbers, color masterbatch and other accessories.

HDPE geomembrane has good physical and mechanical properties, high strength, chemical corrosion resistance, environmental stress cracking resistance, root resistance, puncture resistance and other comprehensive characteristics.

LDPE, EVA elongation, low temperature performance, soft and easy construction.

ECB geomembrane is a mixture of ethylene copolymer and petroleum resin, which is a higher grade geomembrane.
