Efficient depolymerization of polyethylene terephthalate (PET) and polyethylene furanoate by engineered PET hydrolase Cut190 [PDF]

AMB Express, 2022
Key points 1. The increased surface area of PET promotes its hydrolysis by Cut190, supporting the surface erosion mechanism by a two-step process (endo-type scission of a polymer chain and exo-type hydrolysis of depolymerized fragments).

Properties of Polyethylene Terephthalate (PET) after Thermo-Oxidative Aging. [PDF]

Materials (Basel), 2021
The influence of the thermo-oxidative aging semi-crystalline polyethylene terephthalate process on the thermal and mechanical properties was analysed in the article. For this purpose, PET was aged at 140 °C for 21, 35 and 56 days. The research showed that as a result of aging, the amount of the crystalline phase increases by about 8%, which translates ...
