Product introduction
EPDM rubber waterproof membrane is made from ternary ethylene-propylene rubber.
Starring adopts the world-advanced equipment of cold feeding extrusion and continuous vulcanization technology. With the best performance among high polymer waterproof materials, EPDM is of exceptional elasticity and will not split or cracked under normal building movement.
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
