UHMW-PE plate
- UHMW-PE plate features: 1. High impact resistance 2. High wear resistance 3. Anti-corrosion 4. Non-fouling 5. weathering and aging resistance 6. The optimum temperature of the wide 7. flame retardant 8. Light weight, easy installation.
Performance:
Ultra-high molecular weight polyethylene (UHMW-PE) for its viscosity-average molecular weight of 1.5 million -1200 million (ordinary polyethylene 2-3 million) given its superior performance:
1. Abrasive resistance
The wear resistance of UHMW-PE rank first in the plastic crown,and more than a certain metal, The wear resistance of UHMW-PE is in proportion to its the molecular weight, the higher the molecular weight, the better the abrasive resistance.
2. Impact resistance
The impact strength of UHMW-PE,in the highest fame of all engineering plastics,The impact strength of UHMW - PE is 2 times of PC, 5 times of ABS, 10 times more of the POM and PBTP. Impact strength increase with increasing molecular weight,The molecular weight was 2200000 and reached a maximum value, and then continues to rise with the molecular weight gradually decreases .
3. The self-lubricating
UHMW-PE has a low coefficient of friction (0.05-0.11), it is an excellent self-lubricating properties. Second only to the best self-lubricating of plastic polytetrafluoroethylene (PTFE) in the absence of lubrication; when it is working to form a sliding or rotating, its lubricity than steel and brass add lubricating oil even better .
4. chemical resistance
UHMW-PE has excellent chemical resistance,In addition to strong acid liquid fluoride, but at a certain temperature and concentration ability of corrosive media (acids, bases, salts) and organic media (except tea solvent). Immersed in 20 ℃ and 80 ℃ of 80 kinds of organic solvents for 30 days, without the appearance of any anomaly, other physical properties are almost not change.
5. The impact energy absorption
UHMW-PE having excellent impact energy absorption, the impact energy absorption maximum in all plastics. Thus noise damping is very good, with excellent sound deadening effect.
6. Health non-toxic
UHMW-PE with health and non-toxic, fully compliant with the Japanese Health Association, and the US Food and Drug Administration and the US Department of Agriculture approved, can be used in contact with food and drugs.
7. nonstick
UHMW-PE surface adsorption force is very weak, and its anti-adhesion ability is only second to plastic viscosity best PTEE, thus the product surface adhesion with other materials is not easy.
8. hydrophobic
UHMW-PE, low water absorption, typically less than 0.01%, only 1% PA6, thereby forming generally do before drying
