Properties of the resins
  • can be processed as classic thermoplasts
  • biodegradable
  • waterproof
  • small tendency to creep
  • behaves similar to LPC's in the melt, for this:
    • finest surfaces
    • thin walls
    • microparts
  • free from even traces of catalysts!
  • highly crystalline (60 to 70%), for this:
    • excellent resistance to solvents
  • temperature of use: -30 to 120°C
  • shrinkage: 1,3 %
