Applications:

  1. Automotive Industry
    • KOCETAL® K500 is widely used in automotive components due to its excellent mechanical properties and resistance to wear and chemicals. Its low viscosity allows for the production of complex, thin-walled parts.
      • Gears and Rollers: The resin’s high stiffness (tensile strength: ~60 MPa, flexural modulus: ~2,500 MPa) and wear resistance make it ideal for gears and rollers in automotive systems such as window regulators and seat adjusters. Its low friction coefficient (~0.2–0.3) ensures smooth operation and durability.
      • Fuel System Components: KOCETAL® K500’s chemical resistance (resistant to fuels, oils, and solvents) makes it suitable for fuel pump housings and valve components.
      • Interior and Exterior Parts: Its dimensional stability (mold shrinkage: ~2%) and surface finish support the production of clips, fasteners, and trim components with tight tolerances.
  2. Electrical and Electronics
    • The resin’s electrical insulating properties and dimensional accuracy make it a preferred material for electrical and electronic applications.
      • Connectors and Housings: KOCETAL® K500’s low viscosity enables the molding of intricate connector designs with thin walls (wall thickness as low as 0.5 mm). Its dielectric strength (~20 kV/mm) ensures reliable performance in electrical insulation applications.
      • Switches and Relays: The material’s high stiffness and fatigue resistance (fatigue strength: ~30 MPa at 10^6 cycles) support long-term reliability in switch mechanisms.
  3. Industrial and Mechanical Components
    • KOCETAL® K500 is used in industrial applications requiring robust, precision-engineered parts.
      • Bearings and Bushings: Its low friction and high wear resistance (wear rate: ~0.01–0.02 mm³/N·m) make it ideal for bearings and bushings in machinery, reducing maintenance needs.
      • Multi-Cavity Molds: The resin’s excellent flowability (melt flow index: ~20–25 g/10 min at 190°C/2.16 kg) supports high-precision molding in multi-cavity tools, reducing cycle times and improving productivity.
      • Conveyor Components: Used in conveyor belt clips and guides due to its durability and resistance to abrasion.
  4. Consumer Goods
    • KOCETAL® K500 is employed in consumer products requiring high mechanical performance and aesthetic quality.
    • Zippers and Fasteners: Its high hardness (Rockwell M: ~80) and smooth surface finish make it suitable for zippers and buttons in apparel and bags.
    • Household Appliances: Components like knobs, handles, and pump parts benefit from the resin’s chemical resistance and ability to maintain dimensional stability under thermal stress (heat deflection temperature: ~100°C at 1.8 MPa).
    • Sporting Goods: Used in equipment like ski bindings and fishing reel components due to its toughness and low friction.
  5. Office Equipment
    • The resin’s moldability and mechanical properties make it suitable for office equipment components.
    • Printer and Copier Parts: KOCETAL® K500 is used in gears, rollers, and paper-feeding mechanisms due to its low viscosity and wear resistance, ensuring reliable performance in high-speed printing environments.
    • Structural Components: Its stiffness and dimensional stability support the production of frames and supports in office machinery.
