, ultra-high molecular weight polyethylene ranks first in wear resistance among plastics, and the larger the molecular weight, the higher the wear resistance and impact resistance of the material
, ultra-high molecular weight The impact strength of polyethylene is the highest among existing plastics. Even at ℃, it still has quite high impact strength
, self-lubricating
, 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 organic solvents
Corrosion
Ultra-high molecular weight polyethylene is tasteless, non-toxic, odorless, non-corrosive itself, has physiological circulation and physiological adaptability
and non-adhesion< br/> 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 plates, 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 boxes, pump parts, bearing linings, gears, sealing joint surfaces
, other agricultural machinery, ship parts, electroplating industry, ultra-low temperature mechanical parts
3. Our factory specializes in the production of imported materials with ultra-high Molecular weight polyethylene rods are made from high-quality pure ultra-high molecular weight polyethylene powder, with a molecular weight of 10,000 units.
Performance
The abrasion resistance ranks first among plastics, 3 times higher than that of nylon and PTFE, and 10 times higher than carbon steel. Maintains high toughness at liquid nitrogen temperature (℃)
Lubricity is equivalent to PTFE, friction coefficient is onlybr/> Impact energy absorption value is the highest among all plastics, and sound attenuation effect is very good
It has high chemical stability and can withstand the effects of various corrosive media and organic media within a certain temperature and concentration range
It has extremely strong adhesion ability, second only to polytetrafluoroethylene
It is completely hygienic and non-toxic and can be used Suitable for contact with food and drugs
Excellent corrosion properties, low friction coefficient, small specific gravity, and good resistance to high-energy radiation. Application fields: General mechanical components, food packaging and conveying machinery, mechanical parts under cold conditions, pharmaceutical, chemical and textile industries, etc.
