High temperature Poly Lactic Acid resins to accelerate market introduction of bioplastics
The global shift towards a biobased economy has placed pressure on plastic producers to seek alternatives to their oil based plastic products. Biobased PLA technology from Purac allows for the creation of high performance PLA homopolymers which can deliver peak heat resistance of up to 120°C (HDT B). This brings considerable benefits to a range of demanding market segments, including consumer electronics, high heat packaging, automotive interiors, automotive under-the-hood components, apparel and non-wovens.
High performance resins include PLLA homopolymer resins with high stereochemical purity: available in a range of viscosities, specially developed for film extrusion, thermoforming, film blowing, fiber spinning, compounding and injection molding applications. PDLA homopolymer resins with high stereochemical purity are available as a nucleating agent for PLLA homopolymer resins. PDLA, when combined with PLLA, will yield a compound suitable for injection molding or thermoforming that shows both an excellent heat performance and a reduction in the processing cycle time.
PLA compounded blends, containing PLLA and PDLA homopolymers that have been specifically developed for injection molding and extrusion have a heat performance similar to traditional PS, PP and ABS.
