How much does it cost to convert our polystyrene tandem foam extrusion line to run NatureWorks bio-polymers?
The answer to this question depends upon the condition of the individual machinery you wish to convert. For example, some extrusion lines have adequate drive motor capacity, while others do not. PLA is highly viscous, shows minimum shear thinning and has higher extruder drive power requirements than polystyrene. We strongly suggest a mechanical review of your extrusion line and total plant systems before contemplating PLA foam production. This service is provided by our sister company, Plastic Engineering Associates, Inc. (www.pea.cc) on a fixed fee consulting basis.
