CLEVELAND – July 14, 2021 – Avient today announced the launch of ColorMatrix™ Lactra™ Four, One, and Zero additives. To help packaging customers further their recyclability and lightweighting goals, Avient developed this technology for mono-layer PET, one of the most widely recycled packaging materials. Lactra Four, One, and Zero offer light blocking up to 99.9 percent with total inorganic content of less than 4 percent and TiO2 content between 4 and zero percent.

And as an automotive designer, you want each and every one of your vehicles to give drivers and passengers a riding experience just short of nirvana. There’s just one problem: all of that increased usage creates greater wear on components. Seats may also be adjusted more frequently throughout the day to accommodate, for example, one driver’s need to carry a surfboard or another driver’s need to transport four kids to soccer practice.

The company was producing wire for USE-2 (Underground Service Entrance) applications in solar systems. To comply with all of these standards meant covering the wire with more than one layer of jacketing and insulation materials – and that meant running the product through the extruder more than once.  It also complied with the critical standards – UL 4703 for photovoltaic wire, UL 44 for indoor use and VW-1 for flame resistance – enabling streamlined production of wires and cables that meet virtually all specifications for solar USE-2 applications.
