- XP 22250 is designed to be diluted with polyethylene to a final NuPlastiQ® content between 10% and 35%.
- XP 22250 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.
- A typical recommended temperature profile will be in the 160°C – 190°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 22250 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.
- This TDS covers the following BioBlend® XP BioPolymers: XP 22250 and XP 22251

- 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 HDPE 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.

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.
