Extruded PE profiles with a very low coefficient of friction and high resistance to chemical agents are used as a sliding support for plastic modular belts and chains, or as a guiding aid for various purposes. PA-21 profiles are in particular used for serpentine chain return supports. With good wear and chemical resistance and low noise properties they perform well within all types of machinery. They are used in a wide range of industries such as bottling, packaging, materials handling, and food processing.
