A new liquid pigment masterbatch technology that can be used to whiten recycled polyethylene terephthalate (rPET) fibers quickly, cleanly, and efficiently has been developed by the manufacturer and marketer of chemical products Venator Corp., Wynyard/UK.

Based on the company’s established titanium dioxide (TiO2) platform for the fiber industry, the new range is optimized for delustering PET fibers from plastic bottles that will be re-spun into polyester. Hombitan LQ White 100, optimized for semi-dull recycled PET fibers, and Hombitan LQ White 130 for the manufacture of full-dull fibers. Designed for small scale recycled PET projects, conducted on a single extrusion line, both products are simple to use and offer several advantages over solid (pelletized) masterbatch pigment solutions.

Dosed via a precision pump, the new products can be easily incorporated into an extrusion line. Seamlessly homogenized into a recycled polymer melt, they have a higher solid pigment load than pelletized solutions. Designed to withstand temperature changes and pressure fluctuations during processing, they deliver uniform whiteness. In addition, Hombitan LQ products require no pre-processing. Unlike pelletized masterbatches, they are delivered ready to use, in easy to store drums. They can also be used near spinning operations thanks to their liquid formulation.
