HDPE, scientifically known as high-density polyethylene, is a thermoplastic made from the polymerization of ethylene monomers. HDPE sheet is made primarily from HDPE resin through processes such as extrusion or compression molding.
1.High Strength and Toughness: It exhibits high mechanical strength, excellent impact and tensile strength, and maintains excellent toughness even at low temperatures.
2.Excellent Chemical Stability: It exhibits excellent corrosion resistance to most acids, alkalis, saline solutions, and organic solvents, making it an ideal material for chemical containers and tank linings. (This is a key difference from rubber, which will be discussed in detail later.)
3.Extremely Low Water Absorption: Its dense molecular structure makes it virtually non-absorbent and resistant to moisture deformation, making it ideal for humid and underwater environments.
4.Excellent Electrical Insulation: It is an excellent electrical insulating material for use in the electrical and electronics industries.
5.Self-lubricating and Non-stick Properties: Its low surface coefficient of friction prevents adhesion to other materials and provides excellent wear resistance.
6.Odorless and non-toxic: It meets food hygiene standards (such as USDA and FDA certification) and can be used in food processing, medical devices, and other fields.
7.Easy to process: As a thermoplastic, it can be easily welded, bent, and cut by heat fusion, providing great flexibility in processing and molding.
8.Low density: It is lighter than water (density approximately 0.941-0.965 g/cm³) and floats on water.
1.Chemical industry: Linings and panels for electroplating tanks, pickling tanks, environmental wastewater treatment equipment, and chemical storage tanks.
2.Logistics and transportation: Pallets, cargo boxes, and container liners.
3.Food industry: Cutting boards, worktops, and parts for food conveying machinery.
4.Municipal engineering: Underground drainage pipes and cable protection conduits.
5.Other applications: Skis, water sports equipment, children's play equipment, etc.
