摘要: A significant disadvantage of the use polylactic acid (PLA) has been overcome by styrene maleic anhydride copolymer (SMAC) to cause an unexpected increase in heat deflection temperature PLA compound, surpassing a delta improvement 5 °C over alone, at 66 psi as measured using ASTM D648 when blended compound is essentially dried prior use. The also often exceeds threshold 65 temperature. Use compatibilizer and impact modifier further improves industrial versatility resistant compound. Alternatively, calcium carbonate industrially valuable.
