I. UHMW-PE Description
UHMW-PE is a super engineering plastic that is probably not as well known as some other engineering plastics but can out perform its relatives in a number of important areas. UHMW (aka UHMW-PE) offers a combination of excellent properties outstanding abrasion resistance, superior impact resistance, non-sticking and self-lubricating properties and excellent mechanical properties, even in cryogenic conditions. UHMW product reduces noise from impact & vibration. It is a self-lubricating material that is chemical, corrosion, and wear-resistant. And its food safe. The weight is light, the is 1/8 of the rolled steel. Lifespan is longer than steel. The wear resistance is 3 to 7 times than that of carbon steel and stainless steel.
II. UHMW-PE Characteristics
1. UHMW exhibits virtually no water absorption
2, Non-Toxic
3. Low coefficient of friction
4. Corrosion resistant
5. Abrasion and impact resistant
6. Wear Resistant
7. Great liner material for industrial material handling applications
8. No stickness ,food safe
III. UHMW-PE Applications
1. Chemical Engineering: Corrosion and wear resistantance mechanical parts
2. Thermal power: coal handling, storage of coal, warehousing chute lining
3. Coal processing: sieve plate, filter, U-underground coal chute
4. Concrete: cement raw and finished product silo silo lining
5. Grain: food storage or chute lining
6. Mining: sieve plate, chute linings, wear anti-bonding part
7. Food industry: star-shaped wheel, transmission timing bottle screw, bearings, guide
rollers, guides, slide blocks, etc.
