The impact strength of ultra-high molecular weight polyethylene is the highest among existing plastics The highest value in , even at ℃, it still has quite high impact strength
, very good self-lubricity
, and ultra-high molecular weight polyethylene has extremely low water absorption. Therefore, its physical and mechanical properties have nothing to do with the humidity factor in the working conditions. Ultra-high molecular weight polyethylene is chemically stable and can withstand various corrosive media such as acids, alkalis, and salts within a certain temperature and concentration range. And corrosion by organic solvents
, ultra-high molecular weight polyethylene is tasteless, non-toxic, odorless, non-corrosive, has physiological circulation and physiological adaptability
, non-adhesion
, When the molecular weight of high-density polyethylene exceeds 10,000, the embrittlement temperature drops to ℃. Ultra-high molecular weight polyethylene can even be used under the action of liquid nitrogen, and its use temperature can reach below ℃, and still has a certain mechanical strength.
Applications of ultra-high molecular weight polyethylene
, lining silos, hoppers, wear-resistant liners, brackets, chutes and other return devices, sliding surfaces, rollers, etc.
, food machinery guard rails, Star wheels, guide gears, rollers, bearing linings, etc.
Papermaking machinery suction tank covers, deflectors, wipers, hydrofoils
Chemical industry sealing fillers, packing materials , vacuum mold box, pump components, bearing bushings, gears, sealing joint surfaces
