Features & Benefits
- Materials Features
- Processing Considerations
- XD 25250 is designed to be diluted with a customer specific polypropylene to achieve a final NuPlastiQ GP concentration between 10% and 40%.
- XD 25250 can be run on existing process equipment with a few adjustments.
- Injection molded applications with XD 25250 are slightly more sensitive to processing conditions such as temperature profile and cycle time.
- A typical recommended temperature profile will be in the 180°C – 210°C range.
- Depending on equipment, process conditions, and residence time, as temperatures increase in this range the glycerin plasticizer may experience some volatilization. This may cause a slight odor and/or smoke and is expected under normal processing conditions. Always use proper ventilation. See the BioBlend® XP 25250 SDS for details.
- Some equipment (shorter residence time, higher output) may allow for higher processing temperatures (210°C - 220°C).
- If the melt temperature is too hot for the specific blend, some scorching and dark coloring may occur. Lower the extrusion temperature and continue processing until the color lightens to an acceptable level.

- Notes
- Moisture content was measured with an infrared moisture analyzer at 105°C for 10 minutes.
- Mechanical properties were measured on injection molded parts made directly from the 50% NuPlastiQ / 50% polypropylene masterbatch.
- These values are typical properties only and should not be used for specification purposes. End users should confirm results with their own tests.

Storage & Handling
- Storage and Drying
- BioLogiQ BioBlends are dried after production and shipped in sealed moisture-proof bags that are ready to use as supplied. They should be stored indoors in the sealed container away from heat until used.
- If pellets are exposed to a humid environment, they will absorb moisture from the air. If needed, dry pellets by introducing warm dry air at no more than 80°C for 1-4 hours.
- The estimated moisture content of a BioLogiQ BioBlend can be measured with an infrared moisture analyzer at 105°C for 10 minutes. The result of the measurement will not perfectly equal the moisture content, due to possible partial evaporation of plasticizer. The result from this test should be <0.5% moisture prior to processing.
