PPH pipe is a kind of homopolypropylene pipe modified by β-modified polypropylene. It is a new type of pipe that has been developed in recent years. PPH tube has a uniform and fine Beta crystal structure, with good heat setting, high temperature resistance, good chemical resistance, creepability, high tension, good insulation, insoluble in organic solvents, non-drying, non-toxic and other characteristics. It is suitable for various industries such as chemical factories, electronic semiconductor factories, pharmaceutical factories, sewage treatment plants and so on. It has been widely used in high acid and alkali chemical product transportation systems, sewage and wastewater transportation systems, environmental engineering and other fields.
