What Are The Characteristics Of HDPE Pipe Use?

2018/11/30      view:

HDPE Pipe is a high crystallinity, non-polar thermoplastic resin. The original HDPE tube has a milky white appearance and is semi-transparent in a slight section. PE has excellent resistance to most living and industrial chemicals. Certain types of chemicals can cause chemical corrosion, such as corrosive oxidants (concentrated nitric acid), aromatic hydrocarbons (xylene), and halogenated hydrocarbons (carbon tetrachloride).

 The polymer is non-hygroscopic and has good water vapor resistance and can be used for packaging purposes. HDPE pipes have excellent electrical properties, especially high dielectric strength, making them suitable for wire and cable. Medium to high molecular weight grades have excellent impact resistance, both at ambient temperatures and even at low temperatures of -40F. The unique characteristics of various grades of HDPE are the appropriate combination of four basic variables: density, molecular weight, molecular weight distribution, and additives. Different catalysts are used to produce custom specialty polymer. These variables combine to produce HDPE pipe grades for different applications; achieving the best balance in performance.
