WK-801 is a TPA-based polyethylene terephthalate (PET) copolymer developed for a variety of applications, particularly for bottles such as drinking water containers and food packaging. This high molecular weight polymer has an intrinsic viscosity (I.V.) of 0.80.

WK-801 is distinguished by low acetaldehyde content, excellent color clarity, and outstanding I.V. stability. It also provides notable processing advantages, including low processing temperatures, high transparency, and minimal degradation, ensuring efficient and reliable manufacturing.
