elimination of secondary antioxidant phosphites while maintaining or improving resin properties through multiple heat histories. The Baeropol RST technology is also being offered in


the form of preformulated one-packs for the economic stabilisation of recycled polyethylene or recycled polypropylene. These Baeropol T-Blends include traditional stabilisers along with RST to provide high-performance levels for price-sensitive reprocess- ing markets. The blends, which contain both primary and second-

colour and melt stability of the resin. Ultranox 800 has been developed to deliver improved MFR retention and reduced discoloration, combined with increased regrind usage. Addivant also highlighted the latest developments in


its Weston 705, which it describes as a clean and safe drop-in nonylphenol-free liquid antioxidant for polyeth- ylene food packaging. Launched three years ago, the additive is now undergoing commercial trials and testing with more than 15 companies. To meet growing demand, Addivant is investing to increase production capacity of Weston 705 by more than 200% at its Morgantown facility in West Virginia. ❙ www.addivant.com

Arkema announced two new additions to its line of impact modifiers for polyamide resins. Orevac IM300 is intended for use with high fluidity PA polymers and IM800 for PA formulations requiring high impact resistance at low temperatures. The company also announced three new additions to its Lotader product line. Lotader AX8700, AX8570 and AX8930 are claimed to improve the processing of PET, PBT, PPS and PC-based compounds without compromising mechani- cal performance or impact resistance. Also new for the show was Pebax Clear 1200 block amide thermoplastic polyester. Offering a flexural modulus of 1,200 MPa and, as the name suggests, transparency, the new grade provides new opportunities to designers in terms of colouration and back decora- tion. The company says the Clear 1200 grade shares the same low density and good snap-back performance as other Pebax products. ❙ www.arkema.com


Baerlocher revealed new additive products that have been developed specifically to stabilise recycled plastics. They include its Baeropol RST oleochemical- based antioxidants, which allow for the reduction or

Bruggolen TP-H1606 is a new low halogen content copper complex-based heat stabiliser for polyamides from Brüggemann Chemical, which is claimed to provide a significant increase in long-term service life compared to conventional sterically hindered phenols and phosphite blends at temperatures up to 150°C. The company claims that an unreinforced PA 66


stabilised with 0.5 % of TP-H1606 will display a half-life of elongation at break of over 2,000h after ageing at 120°C. The new product is also colour-neutral (even after conditioning), making it suitable for use in natural-col- oured products or lighter shades, and does not have a negative impact on comparative tracking index (CTI). ❙ www.brueggemann.com
