LDPE is a low density polyethylene (Low Density Polyethylene) abbreviation, a semi-crystalline thermoplastic, from the polymerization of ethylene monomer, with good transparency, flexibility and resistance. LDPE is one of the preferred materials for making some lightweight articles.

LDPE is a thermoplastic plastic with low density, good flexibility, strong fatigue, impact resistance and flexibility. LDPE is one of the raw materials widely used in the manufacture of various plastic products. LDPE is produced by polymerizing monomers from ethylene or copolymerizing monomers such as ethylene and 1-octene or 1-butene, depending on the requirements of the final product.

LDPE has a wide range of applications, such as: food truck folding containers, wire and cable protective covers, protective clothing, self-adhesive packaging bags, medical use of air bags, radiator fan blades and so on. In general, LDPE produces products with excellent flexibility, relatively good thermal and barrier properties for durability. The advantages of

LDPE include:

-good flexibility and folding
-waterproof, moisture-proof and cold-resistant
-
physical durability and chemical stability-easy processing and molding

LDPE's disadvantages mainly include:

-too high softness is not suitable for the production of high-demand parts
-high friction, surface can not be used for drawing and printing
-difficult to be used in high temperature and high pressure environment

in general, LDPE is a very useful thermoplastic material that is widely used in the manufacture of a range of complex plastic products. Learning the characteristics and applications of LDPE, we can better understand the types and uses of plastic products, and further understand the basic knowledge and characteristics of products, which will help us to select and develop better plastic products.
