HDPE Non-Pressurized Pipe is a type of pipe made with High-Density Polyethylene (HDPE) and is primarily used in non-pressurized application scenarios. HDPE is a highly crystalline, non-polar thermoplastic resin with excellent resistance to most household and industrial chemicals. In its raw state, HDPE has a milky white appearance, with some degree of translucency in micro-thin sections. This material is non-hygroscopic and has good water-vapor repellency, is suitable for use in wires and cables, has impact resistance in medium to high molecular weight grades, and maintains good performance at room temperature and even at low temperatures.
