New Series Extend Cost-Savings and End-Use Benefits of Company’s Proprietary Color Technology, Making Them Available to the Full Range of PET Processors

PAWTUCKET, RI, U.S.A, January 8, 2007: Teknor Color Company’s PETek (TM) color system is now available not just as the original minibead product but in new alternative forms that provide the same superior clarity and color uniformity in comparison with conventional color concentrates for PET, the company announced today..

Additions to the PETek product range include two standard-size bead and pellet series based on the same proprietary carrier-resin as in PETek minibeads, plus a traditional concentrate series based on a standard PET-resin carrier (see table). Like the minibeads, introduced two years ago, the new concentrates can be used for the full spectrum of film, sheet, bottles, and other molded products. The four series differ little in cost.

“Because the proprietary carrier-resin system developed by Teknor Color incorporates so readily and uniformly in PET, the PETek concentrates based on it impart a degree of haze-free crystal clarity and sparkling, swirl-free color that is unachievable with conventional colorants for PET,” said Meritt M. Siers-Foster, senior research chemist. “As a result, PET processors can significantly reduce scrap rates and enhance the appeal of packaging and consumer products.”

The three new PETek series all come in standard bead or pellet sizes rather than as minibeads, but they address different processing requirements:

• Large-Bead Series. These concentrates contain exactly the same proprietary carrier system as the minibeads. Their larger size causes them to melt later in the barrel and avoid screw slippage.

• Modified Series. The carrier in these concentrates is a modified version of Teknor Color’s proprietary system. Besides reducing screw slippage, they can be used at very high loadings for applications requiring a high degree of opacity.

• Traditional Series. These concentrates have a standard PET carrier resin. They are recommended for prevention of premature melting, particularly when there is little or no provision for cooling at the throat of the processing machine.
