Dehumidification of polymeric materials
Cartigliano towards dehumidification of polymers!
Recently graduated at Ca’ Foscari University of Venice, Ms. Pesavento presented an experimental thesis on the dehumidification of polymeric materials with the application of Radio Frequency technology.
During the difficult period of the COVID-19 pandemic, Cartigliano Research and Development Department never stopped working; on the contrary, it continued the cooperate with the Ca’ Foscari University which allowed the recent graduate Laura Pesavento to carry out her studies on the dehumidification of polymers helped by Eng. Fernando Bressan.
The project is still under development, but aims to reduce the humidity present in the polymers through Radio Frequency Technology which, unlike the processing with hot air, allows to reduce drying times and to use low temperatures. The focus for Cartigliano is to make the polymer drying process as efficient as possible.
The treated materials were chosen on the basis of hygroscopicity and polarity criteria and are: PA6 (Polyamide 6), PBF3560 (innovative copolymer) and PP (Polypropylene).
They were analysed externally with Plantura Italia srl which performed the characterization of the polymeric material before and after the dehumidification process. Furthermore, in collaboration with the University, a morphological characterization was carried out on the polymeric material.
