Material Notes:
Heat resistance higher than typical PLA is achieved by addition of a nucleating agent and PDLA homopolymer. Increased modulus is produced by addition of talc to the base grade. Data is for samples produced from Puralact L and D lactide monomers. PLA is 100% biobased and is both recyclable and compostable. PLA can be used in a broad range of applications from molded plastic parts to textiles, foams, and films. Information provide by Corbion Purac.
