Product Details

Chlorinated polyethylene (CPE) waterproof membrane

★ Product overview

Chlorinated polyethylene waterproofing membrane developed by our factory, the production of a new type of high strength road and bridge special polymer waterproofing membrane, this product is based on chlorinated polyethylene as the base material, adding modifier, anti-aging agent, accelerator and some other reinforcing agent, after mixing rolling double-sided composite. It has the comprehensive characteristics of large tension, high resilience, oil resistance, flame retardancy, weather resistance and long service life. The product is cold construction type waterproof material, construction operation is convenient, and is not limited by climatic conditions.
