Application of polyethylene

Time:2021-7-29

Polyethylene is used in the manufacture of films, pipes, wire and cable materials, monofilaments, daily necessities, hollow products, foams, coatings and adhesives. But unmodified PE cannot be used as engineering material. The material rigidity required by engineering structural materials is usually 800~1000MPa, the strength is above 100MPa, and the heat resistance is 130~150℃. It can be seen that if polyethylene is used as a structural material, it must be modified to improve its strength, rigidity and heat resistance, so that these three properties can at least reach the level of general engineering plastics, especially the performance of reinforced plastics. Level before it can be used as engineering structural materials.

The only way to realize PE engineering is modification technology. At present, more than 80% of the commercially available PE resins in developed countries are modified PE resins, and the use of modification technology has a very important position and role in the development of high-performance and low-cost engineering materials.
