POLYMER MATERIAL BASED ON POLYLACTIC ACID

摘要

The invention relates to a polymer material comprising a mixture of: a base polylactic acid (PLA) polymer formed by between 60 wt.-% and 85 wt.-% L units and between 15 wt.-% and 40 wt.-% D units or between 60 wt.-% and 85 wt.-% D units and between 15 wt.-% and 40 wt.-% L units; and a plasticiser selected from the group containing citric acid esters, glycerin esters and derivatives, poly(alkylene ethers), oligomers of lactide or derivatives of lactic acid, fatty acid esters and epoxidised oils, representing between 10 wt.-% and 40 wt.-% in relation to the total weight of the polymer material.
