Polyethylene (PE) Sheet, Coil, and Film: Features and Applications
Polyethylene (PE) Sheet, Coil, and Film are widely used thermoplastic materials in various industrial and commercial applications. Polyethylene, derived from ethylene, is commonly known as PE in the plastic industry. Ethylene is a molecule with the chemical formula C2H4, composed of two CH2 units bound by a double bond (CH2=CH2). The production of polyethylene occurs through the polymerization of ethylene, and this process can be carried out using various polymerization methods, including radical polymerization, anionic polymerization, ionic coordination polymerization, and cationic polymerization, each resulting in different types of polyethylene.
Classification of Polyethylene
Polyethylene is classified into various categories based on its density and chemical properties. The mechanical properties, molecular weight, crystalline structure, and branching type of polyethylene are the primary factors that influence this classification. The main PE types used in sheet production are as follows:
- HDPE (High-Density Polyethylene)
- MDPE (Medium-Density Polyethylene)
- LDPE (Low-Density Polyethylene)
Properties of Polyethylene
Polyethylene's properties may vary depending on the type used. However, in general, polyethylene is known for its excellent resistance to environmental conditions and moisture, flexibility, low mechanical strength, and superior chemical resistance. It is commonly used in products such as containers, boxes, kitchenware, coatings, pipes and tubes, toys, insulating layers in cables, and packaging/films. Additionally, polyethylene is a cost-effective material, and its antistatic properties help minimize static charges that may develop after production, preventing the products from being affected by dirty environmental conditions.
