LLDPE polyethylene in the chemical production of raw materials in the field of the nature and use of

1. Introduction

LLDPE polyethylene is a widely used chemical production of raw materials, because of its unique properties and a wide range of uses, it occupies an important position in the plastics industry. This article will detail the properties and uses of LLDPE polyethylene.

2. The properties of LLDPE polyethylene

1. Thermal properties: LLDPE polyethylene has high heat resistance and can be used in a certain temperature range. At the same time, it has good thermal stability and is not easy to decompose.

2. Mechanical properties: LLDPE polyethylene has high tensile strength and toughness, easy to process and shape, and has excellent impact resistance.

3. Electrical properties: LLDPE polyethylene has excellent electrical insulation properties and can be used in the manufacture of electrical equipment such as wires and cables.

4. Chemical stability: LLDPE polyethylene has good stability to acid, alkali and other chemical reagents, and is not easy to occur chemical reaction.

3. The use of LLDPE polyethylene

1. Film production: LLDPE polyethylene is widely used in the production of various films, such as food packaging film, agricultural film, etc. Due to its excellent mechanical properties and heat sealing properties, LLDPE polyethylene has become one of the main raw materials for film production.

2. Injection molding products: LLDPE polyethylene can be used to produce various injection molding products, such as containers, pipes, pipe fittings, etc. Because of its good fluidity and processing performance, LLDPE polyethylene has become one of the commonly used materials for injection molding products.

3. Extrusion products: LLDPE polyethylene can be used to produce various extrusion products, such as pipes, profiles, etc. Because of its good extrusion performance and mechanical properties, LLDPE polyethylene has become one of the main raw materials for extrusion products.

4. Wire and cable: LLDPE polyethylene has excellent electrical insulation properties and can be used to produce insulation materials for electrical equipment such as wires and cables.

4. conclusion

LLDPE as an important raw material for chemical production, has a wide range of uses and excellent properties. In the future development, with the continuous progress of science and technology and the continuous expansion of application fields, the position of LLDPE polyethylene in the field of chemical production raw materials will be more stable.
