PE sheet because of its good corrosion resistance, fluid resistance, chemical stability and other characteristics, with a wide range of applications.
PE sheet material called polyethylene plate color plate. PE sheet is a high crystallinity, non-polar thermoplastic resin. Original state of HDPE milky white, the thin cross-section was a certain degree of translucent. PE sheet is mainly used in drinking water, process water, waste water, natural gas and other media. But its anti-aging properties better than PP and therefore rarely used ordinary materials PE pipe installation on the ground, unless the anti-aging treatment process (such as adding anti-aging agent). Certain types of chemicals will undergo chemical corrosion, such as corrosive oxidizer (nitric acid), aromatics (xylene) and halogenated hydrocarbons (carbon tetrachloride).
PE sheet of the color plate to achieve the best balance between performance. It has good chemical stability, resistant to most acids, alkalis, organic solvents and water erosion, and good electrical insulation.
High wear resistance. One of the most striking properties of high molecular weight polyethylene is that it is extremely resistant to abrasion, a performance that is invaluable in many engineering applications. In all plastics, its wearability is the best, and even many metal materials (such as carbon steel, stainless steel, bronze, etc.) are not as abrasive as it is. As the molecular weight of polyethylene increases, the material becomes more and more durable.
Extremely high impact resistance. Ultra-high molecular weight polyethylene impact strength and its molecular weight, molecular weight is less than 2 million, with the molecular weight, the impact strength increased, reached a peak around 2 million, after the peak, the molecular weight and higher impact strength decreased. This is because the molecular chain interferes with its light-crystal effect, allowing large, amorphous areas in large molecules to absorb larger shocks.
Low friction coefficient. Ultra-high molecular weight polyethylene is very wear-resistant, and the friction coefficient is low, self-lubricating is good, is an ideal bearing sleeve, slide block, lining material.
