  2. Since the discoloring of resin or the rusting / corrosion of processing machines occur depending on conditions, avoid severe processing conditions.
  3. As for the screw, mold, and other parts of a processing machine, which directly contact with high-temperature resin, use materials with corrosion resistance in such a way as applying hard chromium plating.
  4. Clean the equipment carefully after use.
