Bioplastics can be more colorful, thanks to new masterbatch choices from Clariant
Article Type: New products From: Pigment & Resin Technology, Volume 40, Issue 2
With the addition of a new line of masterbatches that comply with standards governing compostability and ecotoxicity, producers of products and packaging made from biopolymers have a wider range of options in color and performance-enhancing additives. Choices range from masterbatches based on conventional, man-made ingredients to those incorporating all-natural materials drawn from renewable sources like plants. Now an attractive third option has been introduced. These and other color and performance innovations for the plastics industry are on display in Hall 8 A, Booth J11 at the K2010 plastics exhibition being held in Dusseldorf, Germany, October 27 to November 3.
“Until recently, companies developing products from biopolymers like PLA and Mater-Bi® had a difficult decision,” explains Hendrik Kammler, Global Head of Segment Additives, Clariant Masterbatches. “They could use all-natural masterbatches and accept that the range of colors and additives available was limited, expensive and not very process- or light-stable. Or, they could use conventional pigments and functional ingredients and compromise on the environmental friendliness of their product. Now, we can provide them with a very attractive third alternative.”
RENOL®-compostable colors and CESA®-compostable additive masterbatches incorporate conventional (non-natural) additives and pigments in a biopolymer carrier resin. Testing of the ingredients, completed in the independent laboratories of OWS nv (Gent, Belgium), determined that the materials can comply with EN 13432:200 – the widely recognized standard for heavy-metal content and plant toxicity.
In addition, Clariant has obtained the highly desirable “OK compost” certification issued by AIB Vinçotte International (Vilvoorde, Belgium). The products made at two Clariant facilities in Europe have obtained the Vinçotte approval stamp for the range of new eco-friendly masterbatches they manufacture.
