DuPont Biomax Thermal 300, is a proprietary heat-stabilizing modifier that allows polylactic acid (PLA) thermoformed packaging to withstand elevated temperatures. Its introduction extends the use of PLA to applications beyond chilled-storage packaging. Now PLA thermoformed packages can be stored shelf stable, shipped normally and even re-heated in the microwave without deformation.

Biomax Thermal 300 is a U.S. Food and Drug Administration-compliant polymer modifier that increases the dimensional stability of PLA packaging materials to temperatures of up to 95°C when used at recommended levels (between 2 percent and 4 percent by weight) and in two-stage forming processes, far above temperatures that packages could be exposed to during storage and shipping. Biomax Thermal contains 50% renewably sourced content by weight.

Benefits of Biomax Thermal

* Raises end-use temperature threshold of PLA articles (demonstrated to be dimensionally stable up to 95 C)
* Reduces shrinkage at temperatures greater than PLA’s natural glass transition temperature
* Offers some toughening benefits
* Only minimally affects haze
* Renewably sourced modifier (50% RS content)
* U.S. and EU compliant for food contact
