General Processing Recommendations

Due to the hydroscopic nature of the natural fillers in this material, pre-drying the resin may be required.  Green Dot recommends that the moisture level of the resin not be above 0.3% as measured by loss-in-weight at 300¬°F for 15 minutes.  If the moisture is above the recommended level, the resin should be dried in a desiccant dryer at 150°F until the moisture is at or below the recommended level.  Failure to dry the material can cause processing problems normally associated with moisture in plastics. 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 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.

Technical Details & Test Data

General Processing Conditions

• Green Dot’s Terratek® SC50 resin needs to be dried before processing if the moisture is above 0.5%. Resin will dry quickly at 220°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.
