What is the difference between the HDPE pipe and the PE water supply pipe?
Now almost all the industry to add materials, manufacturers do not have very few. We are the space of subordinate enterprises, but also the production of steel reinforced polyethylene spiral corrugated pipe and steel skeleton plastic composite pipe, we are not added back to the material, but our price is relatively high, after all, is a quality of a price. To say that the proportion of materials used to add, there are many, and some even all of the materials used to produce, it is difficult to imagine.
LDPE is mainly used in film applications. It has good transparency and good processability, but its mechanical properties are poor.HDPE has many applications: wire drawing (woven fabric fiber), injection molding (various daily necessities), film blowing (i.e., film applications), hollow (blow molding, such as some PE bottles)PE polyethylene plastic, the most basic kind of plastic, plastic bags, plastic wrap, etc., are PE.HDPE high density polyethylene plastic, English name is "High Density Polyethylene", referred to as "HDPE"".HDPE is a thermoplastic resin of high crystallinity and non polarity.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 a good water vapor resistance and can be used for packaging purposes. HDPE has good electrical properties, especially insulation, dielectric strength, so that it is suitable for wire and cable. Medium to high molecular weight, with excellent impact resistance, at room temperature, even at -40F low temperatures.Because of the high density HDPE tube is used more, usually with high density HDPE tube on behalf of pe.
1, the high and low pressure here mainly refers to the reaction conditions of the production process, that is, a high-pressure process, and a low-pressure process.2, the density of the difference, a high, a low.
The two are tubes of PE, HDPE is HDPE, and PE is polyethylene. But the physical properties are different.High pressure polyethylene (LDPE), the full name of high pressure low density polyethylene, the industry generally referred to as high-pressure.Low pressure polyethylene (HDPE) full name low pressure high density polyethylene, referred to as low pressure.
