Polyethylene (PE) Self-adhesive Waterproof membrane

Description

Description Polyethylene (PE) Self-adhesive Waterproof membrane is a new polymer waterproof membrane which is made from secov polymer sheet which coated with non asphalt self-adhesive compound membrane,processed into the Environment-friendly and self adhesive polymer waterproof membrane.

Feature

Feature (1)Small density ,high recovery rate,independence bubble structure.
(2)Low water absorption on surface, good penetration resistance.
(3)Good acid resistance, alkali resistance,corrosion resistance, excellent ageing resistance, ultraviolet radiation resistance.
(4)Excellent abrasion resistance and penetration resistance.
(5)Easy construction,no pollution.
