In our daily life, many people may know hdpe drainage pipes, but there are also many people don’t know what is HDPE,  what are the characteristics of HDPE? The editor will take you to learn more about HDPE related knowledge in detail.


1.What material is hdpe?
hdpe means high-density polyethylene, which is a thermoplastic resin with high crystallinity and non-polarity. Hdpe was introduced to the market as early as 1956, but this material was far from mature at that time. However, with the passage of time, its technology and manufacturing level have been continuously improved, and high-density polyethylene materials have gradually been accepted by the market.

2.What are the main uses of hdpe?
High-density polyethylene appears as white granule and has many advantages. It is widely used in plastic products, packaging, electronic appliances, daily sundries, automobiles and other fields. Specifically, it can be expressed in the following aspects:
According to different production processes, it can be divided into injection molded products, blow molded products, extruded products, rotational molding and so on. Generally speaking, common injection products include food containers, plastic boxes, trash cans, plastic flowers, bottle caps, etc., while gasoline tanks, food packaging bags, fertilizer lining films, containers, plastic bottles, etc. are all very common blown products. Plastic products.
In addition, extruded products, such as pipes, pipes, and fittings used to transport gas, water, chemicals, etc., are all extruded products. Storage tanks, large containers, boxes, and barrels are usually rotationally formed.

3.What are the characteristics of hdpe?
Hdpe's material is safe and non-toxic, and has no odor, and will not emit a odor similar to other pipes. At the same time, hdpe materials have very good heat resistance and cold resistance, and they have outstanding performance in chemical stability, rigidity, toughness, and mechanical strength. HDPE material has low water absorption, and its insulation properties and radiation resistance are quite excellent. It is precisely because of the above advantages that the application range of hdpe can be so wide and welcomed by the market.
