Commodity resins, like acrylonitrile butadiene styrene, and low-density polyethylene, lack the chemical, thermal and creep resistance, dimensional stability, and other properties wanted in precision gears. Their use is usually restricted to primary, low-load or low-speed gears. The Celanese Plastic Gear Evaluation and Research unit (the P-GEAR unit) is an efficient instance of take a look at gear that generates such information. The complexity of a gear utility implies that the characterization done by the unit for one or more plastics have to be confirmed by the designer within the field before the designer makes a final polymer choice. One strategy …
