K2022 NEWS Clariant eyes chemical recycling
Clariant announced a move into the chemical recycling area at K2022 with the launch of a portfolio of new products developed to improve the quality of products from pyrolysis-based chemical recycling ventures. Projects for chemical
recycling of plastics waste are proliferating, with a large proportion based on pyrolysis technology. However, the pyrolysis oil produced in these facilities is likely to require further processing to remove contaminants before it can be used as a feedstock for new polymer production. Contaminants are highly variable and can include by-products of nitrogen, oxygen, sulphur in differing amounts. Clariant’s new
HDMax catalysts and Clarit adsorbents are tailored to remove a wide range of contaminants that are continuously changing in the feed, which it says enables the flexibility pyrolysis oil producers need regardless of process configuration. Speaking to Compound-
ing World at the show, Clariant’s Global Business Development Manager Séval Schictel said that in small volume pilot plants contaminants are diluted to low levels, but the need for pyrolysis oil purification is becoming important as chemical recyclers aim to start up production scale facilities from 2025 onwards. Schictel said the Clarit adsorbents are designed for
use in the first step, where they target a range of different contaminants to adjust for the variability of the input materials. The second step involves catalytic hydrogenation using the new HDMax catalysts. Clariant also introduced a number of additions to its existing product ranges, including two new grades of Exolit OP flame retardants (1466 and 1480) for use in unattended home appli- ances. AddWorks AGC 970 is its latest light stabiliser, which is intended to extend the service life of PE agricul- tural films by increasing UV resistance and resistance to high levels of agrochemicals. Licowax AS 100 TP is an
anti-scratch additive based on renewable materials for
PP and TPO formulations which enables injection moulded products – such as car dashboards and door panels, household appli- ance casings, lightweight luggage –to maintain their original look and feel for longer. “Expanding the lifespan of products is a key element in the move from a linear to a circular econo- my,” said Martin John, Head of Advanced Surface Solutions at Clariant. The company also launched a new product carbon footprint (PCF) tool. It says the CliMate automated carbon footprint calculator allows it to offer consistent cradle-to-gate greenhouse gas (GHG) emission data for all of its products. �

Delta Tecnic extends masterbatch range
Delta Tecnic, the Spanish-headquartered masterbatch maker focused on PVC and cable applications, introduced a range of new products aimed at specific markets including PVC recycling, EMI shielding and profile extrusion. The company is offering new colour
masterbatches for recycled PVC in black, white and brown. Marketing Manager Eva Gotor said that they all have high concentrations of pigments and are formulated to deliver good dispersion. She added that the white masterbatch has a high titanium dioxide content and includes ingredients to help restore the appearance of recycled white PVC that has yellowed during its lifetime. Delta Tecnic’s new conductive
formulation for cable applications combines carbon black with graphene to give enhanced EMI shielding perfor- mance. It is currently in a trial phase. The company already has a range of
14
commercial conductive products based on carbon black and carbon nanotubes. For window profile applications, the company has introduced a new range of colour PVC masterbatches, which are designed to provide fast dilution, high colour consistency and weather resistance. The range includes popular colour options for window profiles such as various browns, creams and greys. The company offers PVC master-

batches in a range of shapes and sizes including its very fine Criopellets — with particle sizes less than 1,000 microns — small micro pellets, micro pellets and standard pellets. Area Manager Filipa Martins said that using masterbatch rather than powder pigments is a cleaner solution for profile extruders producing their own compounds. It also shortens cleaning times. �
