The working principle of polyethylene sheet is mainly based on its physical and chemical properties.
Polyethylene sheet is a polymer material made of ethylene monomers, which has excellent physical and chemical properties. Its molecular chain structure determines its flexibility and chemical stability. According to the density and molecular chain arrangement, polyethylene sheet is mainly divided into HDPE sheet (high-density polyethylene), LDPE sheet (low-density polyethylene) and UHMWPE sheet (ultra-high molecular weight polyethylene). HDPE sheet has high hardness, wear resistance and high temperature resistance (up to 100°C), which is suitable for industrial equipment and chemical containers; LDPE sheet is soft and impact-resistant, and is often used for packaging and cushioning materials; UHMWPE sheet is known as the "king of plastics", and its wear resistance is 7 times that of steel, and is used in high-end fields such as mechanical guides and bulletproof vests.
