Heat-Resistant Thermoplastic Made From Renewable, Biodegradable and Eco-Friendly Polymer PLA

Technology #z08149

High-Heat Tolerant, Synthetic, Thermoplastic Made from the Polymer Polylactic Acid (PLA)

Heat-resistant thermoplastic, plastic that can withstand high temperatures, can be made from renewable and biodegradable polylactic acid (PLA) using a process developed by University of Minnesota researchers. This heat resistant PLA is derived from the material lactide found in biomass such as corn starch, sugar, wheat, and sugar beets. This thermoplastic is an eco friendly alternative to Styrofoam or petroleum-based plastic due to the environmentally friendly creation process and the available renewable biomass sources.

Heat-Resistant Medical Device, Cup, Package, and Bottle Creation using a Synthetic Thermoplastic created from the Polymer PLA

The PLA, created using our patent pending process, can withstand temperatures of up to 110 [C] (230 [F] ), so can be used to create any plastic object, including those that will be filled with hot liquids or otherwise exposed to high temperatures such as a cups, packages, bottles, or medical devices. Typical PLA has a melting temperature of around 60 [C] (140 [F]), and so their uses are limited. Additionally, this thermoplastic is renewable, biodegradable, and is inexpensive to create because lactide is the starting material and is obtained easily from biomass (corn stalks, sugar cane, wheat, sugar beets etc.).


  • Create heat resistant thermoplastic from renewable biomass
  • Enables the use of PLA for any product exposed to high temperatures like a cup, package or bottle
  • Eco friendly process and material
  • Uses lactide derived from corn starch, sugar cane, wheat, or sugar beets and therefore is inexpensive
