Akestra™ for masterbatches
Adding color or functionality to a transparent polymer starts with selecting the right carrier. Akestra™ is a transparent amorphous copolyester carrier for color and functional masterbatches used in PET, rPET, PETG and selected transparent specialty polymers. Beyond additive delivery, Akestra™ can also contribute to compatibility, optical performance and, in suitable polymer systems, processing performance.
