    General safety instructions, read also Process instructions:

  • Avoid high temperatures an long residence time. At high temperature fibers may degrade and can result in pressure build up in machine.
  • Avoid large piles of purged material, can start to smolder
  • Keep reject material from flammable materials, let cool before disposal i.e in water
  • Processing methods

    Drying: 2 hours at 105°C

    Injection moulding machine Temperatures:

  • Nozzle temp: 180 - 205°C
