But there are Some rubber expansion joint products begin to age rapidly, crack and crack 1-2 years after installation. , The main reason for this is the use of reclaimed rubber in the rubber mixing process. During the use process, the inner and outer rubber layers cracked rapidly, mainly because the reclaimed rubber was used in the raw materials, and the physical and chemical properties of the reclaimed rubber did not meet the standards. The adhesion between rubber and nylon cords is poor, resulting in the delamination of rubber and cords, which is like the delamination of steel bars and cement in buildings. This kind of physical and chemical properties are degraded and cannot be used as raw materials for rubber expansion joints. However, some manufacturers are interested in using recycled rubber to reduce costs and participate in vicious market competition. The rubber expansion joint is mainly composed of the outer rubber layer, the polyester cord reinforcement and the inner corner layer. In the expansion movement of the two to absorb the displacement of the pipeline, there is inconsistency, causing the rubber to crack and crack.

Shanghai Songjiang Group promises to use [NR] natural rubber and never use reclaimed rubber, Company has established a complete set of quality assurance testing system and strict after-sales service management systems to assure product quality.
