PET chip is TPA-based polyethylene terephthalic copolymer designed for various applications, especially for the bottle like drinking water & food container. It is a high molecular weight polymer.
It is low acetaldehyde content, good color, viscosity stability and low heavy metal content features, excellent further processing features like low processing temperature, high clarity and little degradation.
