Service life is higher than steel, wear resistance is 3-7 times that of carbon steel and stainless steel; low friction coefficient, self-lubricating, does not absorb water or adhere to materials, high impact strength, excellent overall mechanical properties, resistant to acid, alkali, salt corrosion, does not age, withstands low temperatures, hygienic and non-toxic, lightweight, with a specific gravity of 1/8 that of steel. Therefore, it is used as a lining material for bulk material storage and transportation equipment, such as storage bins and chutes.
