Problems solved by technology

Polyethylene is a large variety of thermoplastics. It has the characteristics of light weight, non-toxicity, and excellent chemical corrosion resistance. However, polyethylene has a very low oxygen index and is a flammable material. Polyethylene will produce serious melting when it is burned. Dripping behavior, which brings great difficulties to flame retardancy. In addition to being flammable, polyethylene has high volume resistivity and surface resistivity, which makes it very difficult to charge static electricity during processing and use. Difficult to eliminate, the above two shortcomings have brought great safety hazards to the use of polyethylene and reduced the scope of use
