Service life is higher than steel, wear resistance is 3 to 7 times that of carbon steel and stainless steel; low friction coefficient, self-lubricating, does not absorb water, does not adhere to materials, high impact strength, excellent overall mechanical properties, resistant to acid, alkali, salt corrosion, does not age, resistant to 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.
