Cereplast has launched a bioresin based on NatureWorks polylactic acid (PLA) that it says can be used as a compostable high-temperature-resistant thermoforming plastic. CP-TH-6000 joins 15 grades of compostable resin, and it has a high-temperature limit of up to 155°F, up from a temperature resistance of 105°F for unmodified PLA. To increase the temperature resistance, Cereplast applied nanotechnology and a patented process technology.
In an interview with MPW last year, Frederic Scheer, Cereplast (Hawthorne, CA) CEO, said the company has a longstanding research agreement focused on nanotechnology with the University of Valencia in Spain. “We see nanomaterials as being a tremendous help to bridge the gap in terms of issues you have with agricultural feedstock as compared with petrochemical feedstock,” Scheer said, adding that at the time, the company was experimenting with nanoclays as a functional additive.—[email protected]
