\net \u00e0 des temp\u00e9ratures sup\u00e9rieures \u00e0 100\u00b0C, sa r\u00e9sistance chimique d\u00e9passe celle de la plupart des m\u00e9taux et autres mat\u00e9riaux.

\ncontamination. R\u00e9sistant aux attaques de divers produits chimiques. Seuls l'acide fluorhydrique, l'acide phosphorique tr\u00e8s fort et l'acide sulfurique peuvent \u00eatre utilis\u00e9s.
\nles solutions chaudes et alcalines dont la concentration et la temp\u00e9rature augmentent, attaquent de plus en plus la surface
