| Product Description: |
| Weldable EPDM rubber waterproofing membrane developed by Renqiu Yongxing Rubber Products Co., Ltd. is a high-elastic waterproof material with the best performance in polymer waterproofing materials. The product is based on EPDM rubber, and is added with a proper amount of polyolefin-based heat soldering agent, carbon black, accelerator, etc., and is processed by cold feed extrusion through continuous vulcanization process equipment. It has the weather resistance and aging resistance of EPDM rubber, and the joints are welded by hot air blower, which overcomes the complexity of the adhesive construction of EPDM coils, making the joints more stable and waterproof. At the same time, our R&D team has further introduced the optimized products of welded EPDM waterproofing membranes: composite type, self-adhesive type, root-resistant puncture type for planting roofing, etc., and various options allow you to work in different construction environments. Complete engineering goals quickly and efficiently. |
| Features: |
| * Strong weldability: the joint can be directly welded, and the overall waterproof layer is formed after welding to ensure the waterproof quality. *Mechanical performance, stable durability and anti-aging performance, its oil and solvent resistance is better than general-purpose neoprene. * Good heat resistance and cold resistance can be used in the range of + 150 ° C to -50 ° C, and is not damaged. *High tear strength and elongation, and strong adaptability to shrinkage or cracking of buildings. * Light weight (0.90~0.97), uniform appearance quality, good flexibility and elasticity. * Good dimensional stability, small amount of heat shrinkage, small deformation, and maintain good condition during construction. *Environmental type, no harmful substances are produced during production, construction and use, and can be recycled without building waste. * It has high tensile strength and good resistance to root puncture: it has good impermeability and impact resistance: corrosion resistance and microbial resistance. |

Application
1) Roofs, basement, toilet, bridge, underground, tunnel and dam.
2) Industrial and civil building waterproof.
3) Geo-synthetic liner for swimming pool, channels, irrigation system.
4) Especially for projects with high requirements in durability, anti-corrosion and deformation.
| Packaging, storage and transportation: |
| 1. Waterproof materials should be stored under dry and ventilated conditions. |
| 2. Different types of membranes must be piled separately. |
| 3. Under usual condition, storage period is one year since production date. |
| 4. Waterproof materials should be put vertically during transportation. |
| 5. It should be kept away from sunshine and rainwater. |
| 6.Transport and storage process should be away from the fire source, storage temperature does not exceed 35 ºC, the storage period is 1 year. |
