Polyethylene Pipes

Polyethylene pipes, High Density Polyethylene is a thermoplastic Polyolefin material generated from the polymerization of ethylene. It is manufactured in petrochemical plants with petroleum as the raw material. Depending of the polymerization process, different types of polyethylene materials are obtained. HDPE, with a density of 0.94 ̴ 0.96 gcm³ is manufactured at low pressure. Several modified copolymers have been developed in recent years. A recently developed grade, often termed as PE 100 with a density of 0.95 ̴ 0.965 gcm³, has significantly higher strength properties than normal HDPE. It is especially designed for the production of larger diameter & thick walled pipe, but can be processed for the whole range of diameters. It also shows excellent resistance to rapid crack propagation and slow crack growth.
