Polyethersulfone is a new high-temperature engineering thermoplastic with an outstanding long-term resistance to creep at temperatures up to 150°C. It is also capable of being used continuously under load at temperatures of up to about 180°C and, in some low-stress applications, up to 200°C.... While the sulfone group confers high-temperature performance, the ether linkage contributes toward practical processing by allowing mobility of the polymer chain when in the melt phase.... Polyethersulfone is especially resistant to acids, alkalies, oils, greases, and aliphatic hydrocarbons and alcohols. It is attacked by ketones, esters, and some halogenated and aromatic hydrocarbons.  3, fiche 1, Anglais, - polyethersulfone

PETG, glycol-modified polyethylene terephthalate, is a copolyester that is a clear amorphous thermoplastic. PETG sheet has high stiffness, hardness, and toughness as well as good impact strength. Unstressed PETG exhibits good resistance to dilute aqueous solutions of mineral acids, bases, salts, and soaps. PETG also has good resistance to aliphatic hydrocarbons, alcohols, and a variety of oils. Halogenated hydrocarbons, low molecular weight ketones, and aromatic hydrocarbons dissolve or swell this plastic. PETG does not contain a UV inhibitor and it is not suggested for use in applications involving continuous long-term outdoor exposure.  6, fiche 4, Anglais, - poly%28ethylene%20terephthalate%29%20glycol
