Popularization of PE and PE tarpaulin
PE:The chemical name is polyethylene, which is a semi-crystalline thermoplastic material and is the material for manufacturing PE tarpaulins . So what are the characteristics of PE? We learned that polyethylene is odorless, non-toxic, feels like wax, has excellent low temperature resistance, has good water absorption, good electrical insulation properties, and can be used normally at -70 to -100 degrees Celsius. , good chemical stability.
PE tarpaulin is generally produced using HDPE (high-density polyethylene). This material has a high operating temperature, good hardness, mechanical strength and chemical resistance. Polyethylene is suitable for hollow blow molding, injection molding and extrusion of various products (hard), such as various containers, nets, packing tapes, and can be used as cable coverings, pipes, special profiles, sheets, etc.
PE tarpaulinThe raw material generally refers to colored striped cloth, which is made of PE woven cloth coated with PE film on both sides. Polypropylene woven cloth is also used. The production process is: drawing-circular weaving- Double sided lamination. The waterproof performance of this kind of tarpaulin is poor. Generally, the waterproof performance cannot be guaranteed after one use. The disadvantage is that it is easy to wear and tear. The advantage is that it is light in weight, clean and pollution-free. It is generally used for temporary storage of goods to protect against rain and dust, and is not suitable for long-term use in the open air.
