PET NANOCOMPOSITE WITH MODIFIED CLAYS, SHOWING IMPROVED PROPERTIES - Banco de Patentes

ITENE has developed a modified clay which is incorporated into PET, which improves the mechanical and barrier properties of this polymer.

It consists of a clay intercalated with a polyester, preferably a polyadipate, which is more stable to high temperatures as compared to other modified clays. This allows to process the modified clay jointly with polymers that show high melting temperatures, such as PET.

Incorporating such modified clays into PET results in PET nanocomposites with improved mechanical and barrier properties and lower rigidity; whilst maintaining their thermal degradation resistance.
