Additives for Polymers (v.2008, #8)
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. According to Clariant, CESA-natur additive masterbatches, along with the RENOL®-natur colour masterbatches introduced in 2007 [ADPO, September 2007], are ideal for use with environmentally friendly biopolymers such as polylactic acid (PLA), which are becoming popular in ‘green’ packaging and consumer goods applications.
Clariant Masterbatches has also recently introduced a range of colour masterbatches that have been specially formulated for use with Purell brand medical-grade polyolefins made by LyondellBasell. The new products extend the company's existing Remafin® line and were introduced to the North American market at the MD&M-East show held in New York in early June.
