Processing Considerations

• XP 24250 is designed to be diluted with polyethylene to a final NuPlastiQ® content between 10% and 40%.
• XP 24250 can be run on existing process equipment with a few adjustments.
• Films made with NuPlastiQ are more sensitive to processing conditions such as temperature profile, residence time, die gap, and blow-up ratio. See the NuPlastiQ Film Processing Guide for additional information.

1. A typical recommended temperature profile will be in the 160 °C – 190 °C range.
2. 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 24250 SDS for details. 

• Some equipment (multi-layer, higher output, lower residence time) may allow for higher processing temperatures (190 °C - 200 °C).
• Melt temperatures above 205 °C may cause material degradation, lensing and fish-eyes in the film.
• When extruder operation has to be stopped temporarily, it is recommended to purge the material in the barrel before resuming film processing.

Notes

1. Moisture content was measured with an infrared moisture analyzer at 105°C for 10 minutes.
2. Mechanical properties were measured on injection molded parts made directly from the 50% NuPlastiQ / 50% polyethylene masterbatch.
3. The reported film properties are for a monolayer blown film that was let-down with 50% additional LLDPE to a concentration of 25% NuPlastiQ. The thickness was 1.0 mil, and the blow-up ratio was 2.5:1.
4. These values are typical properties only and should not be used for specification purposes. End users should confirm results with their own tests.

• The MFI of XP 24250 is lower than the MFI of a typical blown film grade of LLDPE ( < 10 1/s). However, as shown above XP 24250 exhibits shear thinning behavior and performs closer to a standard film grade LLDPE under typical blown film conditions (200 1/s).

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.
