LDPE Granules

Field of application and development prospect

Field of application

Application scope of LDPE Granules: It is suitable for packaging of foodstuffs such as seasoning, pastry, sugar, candied fruit, cookies, milk powder, tea, fish and meat floss. Tablets, powders and other pharmaceutical packaging, shirts, clothing, knitted cotton products and chemical fiber products and other fiber products packaging. Laundry detergent, detergent, cosmetics and other daily necessities packaging. Due to the poor mechanical properties of single-layer PE film, so it is usually used as the inner layer of composite bags, that is, multi-layer composite film heat sealable substrate.

Development prospect

Polyethylene is a crystalline polymer. According to its production method can be divided into high-pressure polyethylene, medium-pressure polyethylene, low-pressure polyethylene, corresponding to obtain low-density polyethylene (LDPE Granules), medium-density polyethylene (MDPE) and high-density polyethylene (HDPE). As the performance of linear low-density polyethylene is better than ordinary low-density polyethylene, the development speed is faster, and there is a trend to replace low-density polyethylene.

Polyethylene plastic for automotive use accounts for 5-6% of the total use of automotive plastics, second to PVC, ABS, polypropylene, polyurethane, ranking fifth. Polyethylene is mainly used in the manufacture of air ducts and various storage tanks. In recent years the amount of polyethylene in the car basically did not increase, but the wave of lightweight but promote the plasticization of gasoline tanks, high molecular weight high-density polyethylene (HMWH-DPE) is the main material. Plastic gasoline tanks have been officially used in automobiles in Europe. The Federal Republic of Germany achieved the industrialization of plastic fuel tanks earlier. Japan's research and development work progress faster, but the automotive industry on its industrialization to take a cautious attitude, pay special attention to watch the United States trend. Polyethylene used in the automobile industry basically belongs to the medium and low pressure polyethylene.
