Some Information About HDPE Pipe

- Oct 10, 2017-

HDPE is a thermoplastic polyolefin made from ethylene copolymer. Although HDPE was introduced in 1956, the plastic has not yet reached its mature level. This general purpose material continues to develop its new uses and markets. A thermoplastic resin. The appearance of the native HDPE is milky white and is somewhat translucent in the narrow cross section. PE has excellent properties that are resistant to most life and industrial chemicals. Certain kinds of chemicals produce chemical corrosion, such as caustic oxidants (concentrated nitric acid), aromatic hydrocarbons (xylene), and halogenated hydrocarbons (carbon tetrachloride). The polymer does not absorb moisture and has good protection

PE can be manufactured in a wide variety of different processing methods. Such as sheet extrusion, film extrusion, pipe or profile extrusion, blow molding, injection molding and plastic.

HDPE tube

HDPE pipe is a new product of traditional steel pipe and polyvinyl chloride drinking water pipe.

HDPE pipe must bear a certain pressure, usually choose a large molecular weight and good mechanical properties of PE resin, such as HDPE resin. LDPE resin has low tensile strength, poor pressure resistance, poor rigidity, poor dimensional stability during forming and difficult connection. It is not suitable to be used as material for feed water pressure pipe. But because of its high hygienic index, LDPE, especially LLDPE resin, has become a common material for producing drinking water pipes. The viscosity of LDPE and LLDPE resin is small, the flowability is good and the processing is easy, so the range of their melt index is wide, and the MI is usually between 0.3-3g/10min.
