General Processing Recommendations

Green Dot’s Terratek® WC200140 resin needs to be dried before processing if the moisture is above 0.5%.  Resin will dry quickly at 150°F in a desiccant dryer. Avoid prolonged resin exposure to air during molding or storage as the material can pick up moisture.

For best molding results, larger gates and runners are recommended. The injection pressure required to fill the mold is much higher than typical injection molding grade plastics.  Typical injection molding temperatures are listed below, these are only a guide and may need to be changed based on the particular application :

Rear 350°F to 360°F
Middle 350°F to 360°F
Front 360°F to 375°F
Nozzle 360°F to 375°F
Mold 60°F to 170°F

The melt temperature of the resin should remain below 400°F to prevent the material from discoloring and having a burnt odor.
