Effect of gas saturation conditions on the expansion ratio of microcellular poly(lactic acid)/wood-flour composites
Poly(lactic acid) or PLA and PLA/wood-flour composites were microcellular foamed with CO2 through a batch foaming process. Specifically, the gas saturation pressure and time varied during processing to produce PLA foams with a high expansion ratio. A ten fold expansion ratio resulted in microcellula...
