Later, the Mitsubishi Corporation in Japan also successfully developed the polybutene plastic monomer C4H8. Our pipe industry raw materials and product production process contain no additives. It is a non-toxic, odorless, and high-performance polymer with stable properties. PB resin is a high molecular complex synthesized from 1-butene (BUTENE-1), a special density (0.937) crystalline substance, and a soft, heteromorphous material.

① It not only shares the common properties of other plastic pipes, such as frost resistance and non-scaling, but is also known for its pressure resistance among various pipe materials. It boasts a long-term circumferential stress-bearing capacity. Under three different conditions – medium at 20°C with system pressure at 16 bar, medium at 70°C with system pressure at 10 bar, and medium at 95°C with system pressure at 6 bar – it ensures safe and reliable operation for 50 years with a safety factor of 1.5.
