Pellets are shipped in sealed moisture-proof bags and are ready to be used as supplied. Until used, they should be stored in a sealed container away from heat.. If pellets are exposed to a humid environment, they will absorb moisture. If needed, dry pellets by introducing warm, dry air at 60°C for 1-4 hours. Pellets should be <0.5% moisture content prior to processing.

BC 27255 is designed to be diluted with additional PLA to achieve a final NuPlastiQ concentration between 10% and 40%.; BC 27255 can be run on existing process equipment with a few adjustments.; Injection molded applications with BC 27255 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® BC 27255 SDS for details.; 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.; In order to allow the PLA to crystalize, the recommended starting mold temperature is 90-100°C Some adjustment may be required.
