Precautions for molding

Be aware of the followings and the Material Safety Data Sheet. And to the best of our knowledge, the information contained herein is accurate. However, the manufacturers do not assume any liability whatsoever for the accuracy or completeness of the information contained herein.

  1. Pre-drying of pellets
    Excess of drying temperature and/or time would be caused a color change or change of flow ability.
  2. Suitable cylinder temperature
    Range of the most suitable cylinder temperature is 300 to 340˚C and do not heat over 350˚C.　However, most suitable temperature for each DIC.PPS grades should be confirmed.　Especially for safety, the temperature range of the grades which are filled PTFE* should be 290 to 320˚C and do not heat over 330˚C.
    *: PTFE; Poly Tetra Fluoro Ethylene
  3. Residence time in cylinder
    The followings give a standard, and may vary on grades of DIC.PPS and different conditions.
    • 300˚C: less than 60 min.
    • 320˚C: less than 30 min.
  4. Degradation or decomposition of resin
    In case of degradation or decomposition of resin or any fear of decomposition, reduce the cylinder temperature and purge the resin out.
  5. Shutting down
    When shutting down the operation, purge resin out completely and the heater off.
  6. Do not mix colorants, additives or other resins with DIC.PPS except materials which DIC recommends.
  7. For safety during operation
    8. 7-1. Ventilation system is recommended and especially is necessary for PTFE filled grades.
    7-2. Wear protective goggles and gloves.
    7-3. Keep operator away from nozzle section.
    7-4. Do not touch molten resin without gloves.
  8. Disposal method
    Dispose or incinerate under safe conditions of in accordance with local regulations.
