Masterbatches



Published November 30, -0001
Plastics product developers seeking additive masterbatches that are both biodegradable and renewable can now select several different functional ingredients in the new CESA-natur product line from Clariant Masterbatches. CESA-natur additive masterbatches, along with RENOL-natur color masterbatches introduced in 2007, are ideal for use with the environmentally friendly biopolymers—like polylactic acid (PLA)—which are becoming popular in green packaging and consumer goods applications. The natural masterbatches also can be formulated for use in conventional polymers as alternatives to non-renewable additives.

The new masterbatches—including slip/antiblock agents, UV/light stabilizers, antioxidants and antistatic agents—feature not only a biopolymer carrier resin, but also naturally occurring substances that are completely renewable, biodegradable and, in most cases, compostable. These products have successfully passed strict screening procedures and are available for immediate use. Clariant Masterbatches is continuing research to expand the range of CESA-natur additive masterbatches. Develop­ment and testing is currently underway on natural impact modifiers and metal deactivators for PLA.
