EPDM flexible pond liner

Classication：


EPDM Rubber Waterproofing membranes Pond liner

Products Description

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

1. Special modified molecular structure, can be hot air welding directly , lap solid and reliable, no environmental pollution, solve the current domestic and foreign EPDM adhesive lap existing problems effectively ;

2. long life, anti-aging, used for more than 20 years for roofing material, the underground &the building;

3.high elongation, tensile strength&heat treatment size change is small;

4. resistant to plant roots, anti-puncture, do planting roof waterproof layer;

5.low temperature and excellent flexibility, -45 ℃ without cracking, adapt to  temperature changes;
