Currently, domestically produced EPDM waterproofing materials are mostly 1 meter or 1.2 meters wide. To adapt to the market, break the high tariffs on imported products, and reduce costs, Henan Yuecheng Waterproofing Materials Co., Ltd. has introduced a new production line. In addition to producing 1-meter and 1.2-meter wide EPDM rubber waterproofing membranes, the company's newly introduced production line can now produce EPDM rubber waterproofing membranes with widths of 3 meters, 6 meters, 9 meters, and 12 meters. This significantly reduces material costs, serving both new and existing customers.

I. Product Introduction
EPDM rubber waterproofing membrane is a homogeneous, high-performance single-layer synthetic polymer rubber waterproofing membrane. It is primarily made from EPDM rubber, supplemented with reinforcing agents, plasticizers, anti-aging agents, vulcanization accelerators, and other processing aids. The manufacturing process includes mixing, cooling, filtering, sulfur addition, extrusion, pressurized continuous vulcanization, inspection, and packaging.
II. Product Features
1. A special modified molecular structure effectively addresses the shortcomings of EPDM adhesive lap joints currently found domestically and internationally;
2. Long service life, anti-aging properties; roof materials can last over 20 years, while underground applications can endure up to 50 years;
3. High elongation, relatively high tensile strength, and minimal dimensional changes under heat treatment;
4. Excellent resistance to root penetration, making it suitable for green roof waterproofing layers;
5. Good low-temperature flexibility and adaptability to environmental temperature changes;
6. Easy installation, strong and reliable lap joints, and environmentally friendly;
7. Resistant to chemical corrosion, suitable for special applications;
8. Easy maintenance and low cost;
9. Convenient for detailed processing;
10. Excellent puncture resistance.
III. Application Scope
Suitable for waterproofing projects in industrial and civil building roofs and underground structures, water reservoirs, municipal works, subways, tunnels, and other engineering projects. Particularly ideal for key waterproofing projects requiring high durability, corrosion resistance, and adaptability to deformation.
