Material Notes:

IngeoTM Biopolymer 3251D is designed for injection molding applications. This polymer grade has a higher melt flow capability than other IngeoTM resins currently in the market place. The higher flow capability allows for easier molding of thin-walled parts. It is designed for injection molding applications, both clear and opaque, requiring high gloss, UV resistance and stiffness.
