Dupont has launched one of the first heat stabilizing modifiers for polylactic acid pla in a move to expand the biopolymer&rsquos usage. biomax thermal, a new modifier that allows the cornbased pla material to maintain dimensional stability and not warp or crack at temperatures above about 130° f. Pla has been frequently criticized for its vulnerability in extreme heat, whether a plamade package is sitting in a hot warehouse or the trunk of a consumer&rsquos car. It&rsquos risky to use for some applications because it doesn&rsquot have a high enough heat deflection temperature. primary use of pla right now is in produce or refrigerated food clamshells that remain in the cold chain and are not heated,
There it works very well. the dupont modifer one of two biomax modifiers, the other offering a toughening agent could help pla penetrate into new food packaging applications, coffee cup lids, And clamshells and blisters.
