（OP）EPDM Rubber Waterproofing membranes
Description
（OP）EPDM Rubber Waterproofing membranes is a synthetic rubber, synthetic tire blends as the base material, adding reinforcing agents, softeners, antioxidants, curing agents processing aids to promote mixing by kneading, mixing, extrusion, rolling and curing, shaping and other processes can be processed into sheet curling volume of new high elastic waterproof material.
Features
l Excellent weather-ability, durability and size stability
l Good adaptability to high and low temperature, UV resistant and anti-corrosion
l High tensile strength and good elongation, accommodating to structure movement
l Easy installation, solid joint, and no environmental pollution
l Good rooting penetration resistance
l Service life up to 50 years
Applications
l Roofs, Basements, Tunnels
l Industrial and civil building waterproofing
l Geosynthetic liner for fish ponds, swimming pools, channels, irrigation system.
l Especially suitable for projects with high requirement in durability, anti-corrosion and deformation
