The main material of double sphere rubber joint is neoprene, natural rubber and EPDM rubber, which is resistant to natural changes in weather and can be extended automatically. It adopts mesh steel wire for multi-body protection. It can prevent the product from natural shrinkage and reduce aging rupture in long-term use, and can replace other expansion products widely used in power plants, water plants, sewage plants, chemical and metallurgical industries. Another very important point is that rubber joints are green products, and there is no pollution to human beings and no side effects from using the product.
