Why HDPE seats are good for stadium seats?
HDPE hollow blow molding is often used in our stadium seats. For professional seating manufacturer SHANGHAI SMOYU INDUSTRY CO., LTD, It is because HDPE material has very good working performance. But there are also many people who are not familiar with this field always asking, what kind of material is hdpe? What are the characteristics? Below we introduce HDPE material and its finished products in detail: stadium chair.
1， What is HDPE material?
HDPE material 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 particles and has many advantages. It is widely used in plastic products, packaging, electronic appliances, daily sundries, automobiles and other fields. 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 is the features of HDPE material?
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.
