How to delay aging of PE heat shrinkable film

The products made by PE heat shrinkable film manufacturers can be used in many industries. In the process of processing, storage and use, under the action of light, heat and oxygen, aging phenomena such as fading, embrittlement and cracking will occur. Now let’s take a look? 　　 Because of the high safety of PE heat shrinkable film, it is especially used for food packaging and high-definition rigid polyethylene products. It is also widely used in plastic doors and windows, water pipes, decorative materials. In order to replace other highly toxic plastic heat stabilizers. PE heat shrinkable film is a white powder with an amorphous structure. The branching degree is small, the relative density is about 1.4, the glass transition temperature is 77~90℃, and the initial decomposition is about 170℃, and the stability to light and heat is poor. After prolonged exposure to the sun, it will decompose and generate hydrogen chloride, which will further actively catalyze the decomposition, causing discoloration, and the physical and mechanical functions are also sensitive to decline. In practical applications, it is necessary to participate in stabilizers to improve the stability of heat and light.　　 PE heat shrinkable film is widely used. It is widely used in building materials, industrial products, daily necessities, floor leather, floor tiles, artificial leather, pipes, wires and cables, packaging films, bottles, foaming materials, sealing materials, fibers, etc. Next post: Reasons for the poor adhesion of the polymer protective filmPrevious post: Why does PE heat shrinkable film have spots
