Polyester polymers are characterized by the functional group (R-COO-R) in their main chain like PET (Polyethylene Terephthalate), PBT (Polybutylene Terephthalate), PEN(Polyethylene Naphthalate) and bio-based PLA (Polylactic Acid) and PBS(Polybutylene Succinate) . Polyester products are used today in a wide range of application like textiles, automotive, packing and container due to their different properties.

In the last years AQUAFIL Engineering has made a lot of innovation in the area of polyester production which make plants more flexible, economic and ecological.
