- Process Guidelines
Bioblend LT25B (B/R/C/W/H) can be processed on conventional injection molding equipment. The material is sensitive to moisture and high temperatures (above 190°C); high shear rates shall be avoided. The matrial needs to be dried before processing. Do not keep the material in the heated barrel longer than 5 – 8 minutes; the material is prone to degrade.
