Plastic is often used in our daily life. From small plastic bags, baby bottles, drink bottles, lunch boxes, plastic packaging to large agricultural films, furniture, electrical appliances, 3D printing and even rockets and rockets, plastic is in all of them.

Plastic is an important branch of organic polymer materials, with many varieties, large production volume and wide application. For a wide range of plastics, they can be classified as follows:

1. Plastics can be divided into thermoplastics and thermosetting plastics according to their behavior when heated;

2. According to type of resin synthesis reaction in plastics, resins can be divided into polymer plastics and polycondensation plastics;

3. According to ordered state of resin macromolecules, plastics can be divided into two types: amorphous plastics and crystalline plastics;

4. According to characteristics and scope of application, plastics can be divided into general plastics, engineering plastics and specialty plastics.

Among them, general purpose plastics are most widely used in our daily lives. General purpose plastics refers to plastics with high production volumes, wide supply, low price, and suitable for a large number of applications. General purpose plastics tend to process well when molded, and different processes can be used to form products for different purposes. General purpose plastics include polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polystyrene (PS), acrylonitrile/butadiene/styrene (ABS).

This time we are mainly talking about main properties and applications of polyethylene (PE). Polyethylene (PE) has excellent processing and use characteristics and is most widely used synthetic resin. Its production capacity has long been ranked first among all plastic varieties. The polyethylene resins mainly include low density polyethylene (LDPE), linear low density polyethylene (LLDPE) and high density polyethylene (HDPE).

Polyethylene is widely used in my country and its biggest consumer is film, which consumes about 77% LDPE and 18% HDPE. In addition, injection molding products, wires and cables, and hollow products all consumed in it occupy a large share in structure. Among five general purpose resins, PE consumption ranks first. Polyethylene can be blown to make various bottles, cans, industrial tanks, barrels and other containers, injection molded to make various pots, barrels, baskets, baskets, baskets and other containers of daily use, daily use items and furniture; extrusion casting Manufacture of various pipes, tapes, fibers, monofilaments, etc. In addition, andIt can also be used to make coating materials and synthetic paper for wires and cables. Among many applications for polyethylene, two main areas of consumption are pipes and films. With development of urban construction, agricultural film and various industries of food, textile and industrial packaging, development of these two areas is becoming more and more extensive.
