Polyethylene pesticide bottle

2022-06-06
 

The glass transition temperature of polyethylene material is low, 125 degrees, but it can maintain its mechanical properties in a wide temperature range. The equilibrium melting point of linear high molecular weight polyethylene is 137 degrees, but it is generally difficult to reach the equilibrium point. Generally, the melting point range during processing is 132-135 degrees, the ignition temperature is 340 degrees, the spontaneous combustion temperature is 349 degrees, and the ignition temperature of dust is 450 degrees. The melting index of polyethylene is determined by its molecular weight, When polyethylene materials with different molecular weights are mixed, their melt index also takes a certain value according to a certain law.
Polyethylene in the polyethylene bottle is the most simple polymer organic compound. It is the most widely used polymer material in the world. It is polymerized from ethylene. It is divided into high-density polyethylene, medium density polyethylene and low-density polyethylene according to the density.

The characteristics of polyethylene bottle mainly depend on polyethylene (PE). Many mechanical properties of polyethylene depend on the density and melt index of the material. Its density is 0.9-0.96g/cm ³ Changes in scope. The melt index (melt flow index) of polyethylene has a wide range, which can be more than 0.3-25. Many important properties of polyethylene vary with density and melt index. Many mechanical properties of polyethylene depend on the strength, fracture, deformation, impact and thermal properties of the material.
