Ultra High Molecular Weight Polyethylene Plate

Ultra High molecular weight polyethylene board (UHMWPE board) use and comprehensive introduction
Combined with its unique physical and chemical properties, UHMWPE board is widely used in high-end fields such as industry, medical treatment, and national defense. The following is the analysis of core uses and characteristics:

1. Molecular weight characteristics
The molecular weight is usually between 1.5 million and 8 million (10-20 times that of ordinary HDPE) , giving the material superior wear resistance, impact resistance and self-lubrication.

2. Core Performance
- Wear: 6 to 7 times that of carbon steel, mine transport system life can reach more than 10 times as much steel.
- Impact resistance, the impact strength more than 150 kJ/m squared is suitable for extreme impact scenario.
- Self-lubricating: Coefficient of friction as low as 0.07, no additional lubricant required.
- Corrosion resistance: Strong acid and alkali (except concentrated sulfuric acid and hydrofluoric acid).
- Biocompatibility conforms to ISO 10993 medical certification, used for artificial joint implants such as.

1. Manufacturing of Industrial Equipment and Machinery
Wear parts -: mine conveyor chute hopper lining board, cement lining, extend life expectancy than manganese steel 6-8 times.
Self-lubricating mechanical parts: gears, bearings, guides, reduce equipment maintenance frequency . - Chemical equipment: valve seal ring, acid pump impeller, resistant to corrosive media .

2. Transportation
Vehicle accessories: truck plate, skateboard, train car cushion goods impact and reduce noise
Ship components: anti-collision fender, cabin liner, suitable for seawater corrosive environment.

3. Medical and Life Sciences
Artificial joint: The wear life of the hip socket cup exceeds 20 years, reducing the risk of postoperative inflammation
Medical equipment: surgical instrument handle sliding parts, video equipment, support the gamma ray sterilization.

4. National Defense and Safety Protection
Body armor: multi-layer UHMWPE plate can block the bullet and fragment, 35% lighter than the kevlar fiber.
Radiation shielding : boron modified sheet for nuclear reactor protection devices.

5. New Energy and Environmental Protection
- Wind power equipment : fan blade wear-resistant coating to extend service life [[12]()].
- Hydrogen fuel cell : bipolar plate material replaces graphite, reducing cost [[6]()][[12]()].

6. People's livelihood and Emerging Fields
Ice and snow sports: snowboard bottom, hockey rink fence, -50℃ still maintain toughness food machinery conveyor belt rollers, sauce molding mould, the FDA food contact standard

1. Processing challenge
- Poor melting fluidity, dependent on molding or sintering process [[13]()], ultra high molecular weight (> 6 million) requires special equipment

2. Modification direction
Enhanced thermal conductivity : boron nitride is added to increase thermal conductivity to 3.5W /m·K
Antistatic treatment : Add carbon nanotubes, and the surface resistance is reduced to 10⁶ Ω

3. Future trends
- Infiltration into extreme environments such as aerospace (lunar rover bearings) and deep-sea equipment (compressive layers)

With the characteristics of "light weight, high strength, wear resistance and corrosion resistance", UHMWPE board has become a key material for industrial upgrading and scientific and technological innovation. Its application has expanded from traditional heavy industry to high-end fields such as medical care and new energy, and will further break the performance boundary through molecular weight refinement classification and composite modification in the future.
