1. Solid, modified polyester carrier resin

2. Melting point very close to that of the base PET resin

3. No risk of colorant melting in the color feeders, and no need for additional cooling of the color feeder

4. No delamination or significant loss in IV retention due to the incompatibility of carrier resin and base resin

5. Unlimited shelf life

6. High loadings of pigments, pearlescents, and metallics

7. No messy spills to clean

8. No pumps or tubes to maintain

9. Fast color changeover

10. No screw slippage caused by liquid coating the screw

11. No drum disposal worries

12. No unusable residual color left in the drum

13. Able to be fed accurately at ratios as low as .01%

14. Small, uniform, free flowing, dust free pellets- no oversized or irregular particles

15. Can be used right out of the drum with no pre-drying needed.

16. In closed loop systems where there is no option but to pass the colorant through a drying stage, Pennacle®PET pellets will not soften prematurely, and physical properties of the colorants will not be affected

17. No significant loss in IV retention to the bottle, even when using high let down ratio colors

18. Much higher pigment loadings then conventional PET concentrates mean lower usage rates and lower coloring costs
