Purac to offer PLA resins to accelerate bioplastics production

With its latest polylactic acid resins, Purac intends to help plastics manufacturers transition from oil-based to bioplastics production. The company will be presenting samples of PLA resins to brand owners, converters and compounders who are interested in exploring the benefits of high performance bioplastics. 

The PLA resins allow for the creation of high performance PLA homopolymers which can deliver peak heat resistance of up to 120°C (HDT B). The range of PLA includes:

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: 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. These blends have a heat performance similar to traditional PS, PP and ABS.

In November, Purac sponsored the Perpetual Plastic Project (in photo) which underscores the recyclability of PLA-based plastics. The project has successfully created a ‘do-it-yourself’, interactive ‘Machine’, which provides users with a small-scale demonstration of how easily PLA can be recycled.
