long-term future growth,” says President and CEO Simon Turner. Chinese TiO2


producer LB Group continues


to invest in capacity for production of its Billions pigment grades. A 100,000 tonnes/ yr chloride process plant came on stream this year at its site at Chuxiong in south east China, intermediate TiO2


capacity is


being increased by 100,000 tonnes/yr at its Jinchang site in the north, and a 200,000 tonnes/yr finishing plant is in build at its Xiangyang facility in the east of the country. Key TiO2


products for the


compounding sector include Billions LR-108, a sulphate process grade, and Billions BLR-866, a


chloride process grade suitable for polyolefin masterbatch production.

Foam process aims for pigment-free opaque bottles


Physical foaming specialist Trexel and injection moulding machinery maker Husky Technologies are collaborating, along with several brand owners, to develop a design for injection stretch blow molding (ISBM) of bottles using MuCell foaming technology to create an opacifying centre layer. The goal of the project is to achieve a light blocking bottle without the use of pigments, which would enable the bottles to be recycled in the natural PET recycle stream, according to Levi Kishbaugh, President and CEO of Trexel. “The combination of Husky’s proprietary multi-layer technology with Trexel’s expertise in the dosing of supercritical nitrogen allows for consistent placement of the foam core in the multi-layer preform,” Kishbaugh says. “Encapsu- lating the opacifying MuCell structure with solid PET layers ensures a high-gloss surface finish on the final product.”


Kishbaugh says the foam core layer provides significant light blocking, although not matching the level that can be achieved with pigments. However, while studies are still ongoing, initial trials have shown the foamed bottle can be incorporated into the natural recycle stream without detrimental effect. � https://trexel.com/ � https://www.husky.co/en/
