General Processing Recommendations

Green Dot’s Terratek® BD3018 needs to be dried before processing if the moisture is above 0.1%.  Resin will dry quickly at 150°F in a desiccant dryer, in approximately 2 to 4 hours.  Avoid prolonged resin exposure to air during processing or storage as the material can pick up moisture.

Typical injection molding temperatures are listed below, these are only a guide and may need to be changed based on the particular application :

Rear 310°F to 360°F
Middle 320°F to 360°F
Front 320°F to 360°F
Nozzle 320°F to 360°F
Mold 40°F to 95°F

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