Clariant may be in the process of selling its masterbatch and pigments business but it has not put developments on the back burner, especially in the areas of recycling and sustainability. Speaking at the show, Clariant Head of Business Unit Master- batches Bernd Hägermann said the company had decided to invest in a mini-recycling line that will be installed at its plant at Pogliano in Italy to develop products for the recycling industry. “We aim to emulate all the steps in recycling. The purpose – to get customers to develop projects with us,” he said. Examples of products focused specifically at the
recycling sector include CESA-IR additive master- batches that are sortable using near-infrared (NIR) sorting technology and an extensive range of chain extenders, odour absorbers, and colour brighteners. The company also introduced the CESA Protect
oxygen scavenging masterbatch for use in PET packaging for sensitive products such as fruit juices. CESA ProTect is activated after processing and Clariant claims it is one of the most effective oxygen scavengers for PET on the market. The company says trials of a 23g 0.5-liter bottle with a 3.6% loading of CESA ProTect masterbatch held oxygen levels below 1 ppm for more than 18 months. In its Pigments division, Clariant now offers a full
range of NIR-sortable black pigments covering commodity and engineering resins. These include SolvapermBlack PCR polymer-soluble dye for colouring PS, PET and PC, Graphtol Black CLN pigment for PE and PP, and Polysynthren Black H for PC, PMMA, ABS, PS, PET and PA. Pigments Business Unit Head Edward Gallagher said the company had also developed a new colour matching technology to simplify recycling of
post-consumer resins. “Recyclates are inherently variable and this makes it difficult to colour-match. We’ve worked with Konica-Minolta and its Calibri software to develop an easy way to colour-match PCR,” he said. “We usually get a colour match in three shots.” �

Cromex launched a new high tinting capacity line of black masterbatches based on carbon black recovered from used car tyres. The Brazilian company said its rC-Black line of masterbatches can be used in applications ranging from packag- ing through to automotive. Grades are offered suitable for resins including PE, PP, PET, PS, ABS, SAN, PBT and POM. Cromex says that, as each tonne of rC-Black masterbatch uses 250 end-of-life tyres, it can make a considerable contribution to meeting sustainabil- ity goals. Performance is not compromised, the company claims. “Contaminant control is so rigorous that it does not interfere in the master- batch or final product manufacturing process,” said Cromex Product Specialist, Giovanni Dias. Key claimed features include good dispersion, strong colour intensity and high tinting power. �

54 COMPOUNDING WORLD | December 2019
ExxonMobil presented a new low density Exxtral PP compound family for automotive interior trim parts that displays enhanced colourability, offering car makers the opportunity to meet weight reduc- tion targets while adopting more colourful interiors. “The concept came together as we thought about the cars of the future – connected vehicles, autonomous vehicles, automated vehicles. As those emerge, we think car design will change away from blacks and beiges – with are designed not to distract the driver – to colours,” said Andy J West, PP Global Marketing Manager for ExxonMobil’s PP, Vistamaxx and Adhesion business.
