How should one choose between DURAPLAS® engineering plastic bearings and TEFPLAS® fluoroplastic bearings, and what are their respective performance differences and application scenarios?

DURAPLAS® engineering plastic bearings offer outstanding overall cost-performance, with modified engineering plastics as the main matrix and embedded solid lubricating components. They are suitable for medium-load, conventional-temperature operating conditions, delivering excellent wear resistance and strong impact resistance, but have limitations when facing highly corrosive or ultra-high-temperature environments. TEFPLAS® fluoroplastic bearings use fluorine-based polymers as the core base material, characterized by exceptional chemical corrosion resistance—withstanding strong acids, strong alkalis, and organic solvents—a broader temperature tolerance range, capability to handle high-temperature conditions, and an extremely low coefficient of friction, making them ideal for harsh chemical-media environments. In comparison, DURAPLAS® is predominantly used in general automation, conveying equipment, and general machinery; TEFPLAS® fluoroplastic bearings are primarily used in chemical equipment, electroplating equipment, wastewater treatment systems, semiconductor equipment, and other machinery exposed to highly corrosive media. When equipment involves chemical spraying or immersion conditions, TEFPLAS® fluoroplastic bearings should be prioritized, while DURAPLAS® is preferred for conventional conditions to control overall equipment costs.
