Processing Biodegradable Thermoplastic

Biodegradable thermoplastic such as Jute, Hemp, coconut natural fiber composites exhibit similar processing characteristics as their conventional counterparts, though the resin must be dried prior to processing. Processing temperatures must be kept under about 400° Fahrenheit to prevent shearing, or the buildup of friction which can cause biocomposites to burn, discolor and degrade. In injection molding, lower injection speeds and larger gates and runners can also work to alleviate shear buildup during processing. Biodegradable thermoplastic can also be processed using blow molding, blown film, sheet extrusion and profile extrusion.

Biodegradable thermoplastic can be compounded with other bioplastics to achieve any number of desired performance properties. For example, biodegradable thermoplastic are a good impact modifier for polylactic acid (PLA), a common bio-based and biodegradable polyester. When combined with PLA at a ratio of 30%, biodegradable thermoplastic have been proven to increase the impact strength of PLA by more than 400%.
