Brief introduction of UHMWPE:
UHMWPE is a thermoplastic engineering plastic with a viscosity-average molecular weigh greater than 1.5×106, and is made by polymerization of ethylene under the action of a catalyst. Its molecular weight has reached over 5 million, its five properties of abrasion, impact and corrosion resistance, self-lubrication, and absorption of impact energy are the best among the available plastics. It is called globally "marvelous plastics" UHMWPE, a new star of materials, will present a vigorous life and play an important part in many regions of the national economy.
Characteristics of UHMWPE:
1. Outstanding impact strength even at very low temperature.
2. Excellent sliding abrasion resistance, wear strength several times as large as steel.
3. Very low coefficient of friction.
4. Nonstick, self-lubrication properties.
5. Good chemical resistance.
6. Excellent anti-aging.
7. Hygienic and nontoxic.
8. Lightweight.
9. Hydrophobic, energy absorption and sound-dampening properties.
10. Excellent dielectric and insulating properties.

Typical applications of UHMWPE:
Applications of UHMWPE are very extensive and it mainly applies to following aspects:
1.Building machinery, agriculture machinery, mining machinery; e.g. liners for silos, hoppers, dump trucks, railcars and chutes.
2.Transporting machinery: sliding guide, guide roll, bushing.
3.Packing, container and tubing: open-type pot, bucket, gasoline tank, gas tube, conveying tube of grain.
4.Pulp and paper industry: doctor blade, suction box cover, filter, chain conveyor plate and dewatering plate.
5.Textile machinery: loom picker, shuttle, stick, strap, cap, buffer, gear, pinion and small roller.
6.Chemical industry: pump impeller, pump housing, valve seats and valve gasket.
7.Medical, macromolecular material: artificial articulation, surgical parts.
8.Sport goods: ski and snowboard bottom surface, snowmobile drive sprocket, golf ball core.
9.Aviation and military: bulletproof vest, aircraft seat.
10.Others: lead-acid battery separator, screen plate of nuclear power plant, fishing rope.
