Product Details

EPDM (OP) rubber waterproofing membrane

★Product Introduction

EPDM (OP) rubber waterproofing membrane is a kind of synthetic rubber, synthetic tire blending system as the base material, adding reinforcing agent, softener, antioxidant, vulcanization accelerator and other processing aids by mixing, mixing, extrusion, calendering and vulcanization, shaping and other processes into a new type of sheet can be rolled high elastic waterproofing membrane.

★Features

1. The special modified molecular structure effectively solves the deficiency of EPDM adhesive bonding at home and abroad;
2, long service life, anti-aging, roofing materials can be used for more than 20 years, underground can reach 50 years;
3, high elongation, high tensile strength, heat treatment size change is small;
4, resistant to plant roots, puncture resistance, can be planted roof waterproof layer;
5, good low temperature flexibility,-35 ℃ does not crack, adapt to environmental temperature changes;
6, convenient construction, hot air welding, lap solid and reliable, no environmental pollution;

★Product types and specifications

Varieties: homogeneous, composite and internal reinforcement

Thickness: 1.2mm 1.5mm 2.0mm
