Plastic folding table panel

With the advancement of technology and the rise of outdoor sports, plastic folding tables have gradually come into people’s sight. It has won people’s favor for its extremely small volume, light weight and convenient use after folding. A folding table is composed of a panel and a frame. Today I will introduce the material of the folding table.

High-density polyethylene (HDPE), a white powder or granular product. Non-toxic, tasteless, crystallinity of 80% to 90%, softening point of 125 to 135°C, service temperature up to 100°C;

hardness, tensile strength and creep are better than low density polyethylene;

wear resistance, electrical Good insulation, toughness and cold resistance;

good chemical stability, insoluble in any organic solvents at room temperature, corrosion resistant to acids, alkalis and various salts;

the film has low permeability to water vapor and air, and water absorption Low;

poor aging resistance, environmental stress cracking resistance is not as good as low-density polyethylene, especially thermal oxidation will reduce its performance,

so antioxidants and ultraviolet absorbers must be added to the resin to improve this deficiency.

High-density polyethylene film has a low heat distortion temperature under stress, so care should be taken when applying it.

In this century, a revolutionary progress has taken place in the field of pipelines, that is, “replacing steel with plastic”. With the rapid progress of polymer material science and technology, the deepening of the development and utilization of plastic pipes, and the continuous improvement of production technology, plastic pipes have fully demonstrated their excellent performance.

Today, plastic pipes are no longer mistaken for “cheap substitutes” for metal pipes. In this revolution, polyethylene pipes are favored and are increasingly shining brightly. They are widely used in gas transmission, water supply, sewage discharge, agricultural irrigation, fine particle solid transportation in mines, as well as oil fields, chemicals, post and telecommunications, etc., especially in fields such as It has been widely used in gas transportation.
