Dow and PolyOne Introduce New Generation Impact Modifier for PLA
Dow has selected PolyOne as its exclusive European formulator for converters seeking ready-to-use formulations with PARALOID BPM-520.
5/16/2011 --- Dow Plastics Additives, a business unit of The Dow Chemical, has teamed up with leading provider of specialized polymer materials PolyOne Corporation to introduce OnCap BIO L masterbatches, the latest development in the field of bioplastics for manufacturers supporting the packaging marketplace with environmentally advanced solutions that also offer production efficiencies.
PolyOne’s OnCap BIO L is based on PARALOID BPM-520, a new generation of impact modifier manufactured by Dow that helps improve the impact resistance of opaque, injection-moulded polylactic acid (PLA) products with minimal effect on heat distortion temperature and stiffness.
Dow has selected PolyOne as its exclusive European formulator for converters seeking ready-to-use formulations with PARALOID BPM-520. PolyOne’s OnCap BIO L additive masterbatch broadens the choices available to brand owners looking to use sustainable polymers in applications such as opaque ice cream and food packaging and semi-durable applications such as cosmetic packaging and housing for laptops or mobile phones.
Derived from corn, PLA has a lower carbon footprint than many polymer alternatives, but its brittle nature means that modifiers are required to improve its impact resistance. PARALOID BPM 520 from Dow has been designed specifically for use with PLA injection-moulded resins in order to help provide high impact strength at room and sub-zero temperatures. It also offers benefits in PLA blends such as PLA/PC.
Converters will appreciate OnCap BIO L’s excellent flow properties and ability to maintain part stiffness, while brand owners will welcome its colourability and attractive surface finish. OnCap BIO L and PARALOID BPM-520 can be used in compliance with the Commission Regulation (EU) No 10/2011 on plastics materials and articles intended to come into contact with food and with US Food and Drug Administration (FDA) requirements.
“Brand owners are always on the look out for products which offer improved environmental performance to keep up with consumer demand – but they don’t want to compromise on end-use performance and need to maintain a cost-competitive and efficient production process,” explained Robin Madgwick, Marketing Manager for Dow Plastic Additives.
“We’ve worked closely with PolyOne to offer an effective impact modifier which can be made available in user-friendly, pre-dispersed formats that can help further extend the use of bio-based PLA resins into injection moulded durable and opaque packaging, which is a step forward for the industry,” continued Madgwick.
“Our relationship with Dow allows us to develop a masterbatch family that will broaden the performance window of PLA and that also builds on the market acceptance gained with our OnCap BIO Impact T additives,” explained Marcel Dartée, PolyOne global marketing director for biopolymers. “Our ability to create new applications for PLA within the marketplace will clearly help extend the reach of sustainable solutions in packaging applications and give our customers an eco-conscious alternative previously unavailable to them in an operationally efficient form.”
PARALOID BPM-520 is produced by Dow in Jurong, Singapore. OnCap BIO Impact L is is available for sale in Europe, Asia, and South America.
PARALOI BPM-520 and OnCap BIO L will be officially launched at PolyOne’s stand in Hall 09/E17 at Interpack, a pre-eminent global trade show for the packaging industry.
