Ultra-high molecular weight polyethylene (UHMWPE) is a kind of engineering thermoplastics with more than 2.5 million viscosity-average molecular weight, under the polymerization of ethylene, butadiene monomer in the catalyst.
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.
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。
