and the requirements linked to the degradation stage of the polymer and potential contamination lead to the demand of particular stabiliser systems.” According to the company, its new world-scale


production site at Zhuhai in China, which is now up and running, provides capacity for it to manufacture products to support expected growth in applica- tions incorporating recyclate and virgin polymer. “The production is dedicated to phenolic antioxi- dants such as Rianox 1010, 1076, 1135 and second- ary antioxidants like the phosphite derivative Rianox 168,” says Senior Account Manager Margo Clauss, who is based in Düsseldorf in Germany. “In the coming years, some substrates will be


re-classified or even banned in some regions,” Clauss predicts, referencing certain benzotriazoles and low molecular weight HALS. “Depending on the product class, several UV-absorbers and light stabilisers will be subject to regulatory restrictions, new labelling or even prohibitions. Rianlon is prepared to recommend alternatives in close cooperation with the consumers,” he says. “For most thermoplastics, the combination of a


UV absorber and a HALS is a must to obtain the optimal performance. Our standard range of


products and blends as well as customised blends for individual applications help our customers to manage this challenge,” says Clauss.


Stabiliser gains China’s UniteChem Group, which is already a major player in light stabilisers, is making major investments to extend its global production capacity and enhance local customer support. “Over the past two decades, we have been taking
