Poly(2,6-diphenyl-p-phenylene oxide) (PPPO) is a porous polymer resin based on oxidative polymerisation of 2,6-diphenylphenol. It is mostly known by its trademark Tenax.
Properties
Poly(2,6-diphenylphenylene oxide) is a low bleeding material with a low level of impurities, and has a high thermal stability (up to 350 °C). Before use poly(2,6-diphenylphenylene oxide) should be thermally conditioned with a high purity gas at elevated temperatures to remove any residual components. During conditioning or thermal desorption the presence of oxygen should be avoided. Poly(2,6-diphenylphenylene oxide) reacts with oxidising agents such as
Use
Poly(2,6-diphenylphenylene oxide) is used for trapping of volatiles and semi-volatiles from air such as environmental air and human breath, and for
.Poly(2,6-diphenylphenylene oxide) is used as food simulant for testing the release of chemical substances from food contact materials into food.[1]
