Peak heat resistance of up to 120°C (HDT B) is now achievable with high-performance grades of polylactic acid (PLA) resin from bioresin manufacturer Purac (Lincolnshire, IL). Target applications include automotive underhood components and interiors.
The global shift towards a bio-based economy has placed pressure on plastic producers to seek alternatives to their oil-based plastic products, according to Purac. The high-heat bioresins that it has developed will enable product designers to create environmentally friendly parts for consumer electronics and high-heat packaging, as well as auto parts.
To accelerate further the market introduction of this next-generation PLA, Purac decided to offer a range of specially developed high-performance resins to the market. The range includes:
•PLLA (poly(L-lactic acid)) homopolymer resins with high stereochemical purity
