Polyetheretherketone (PEEK)

Polyetheretherketone (PEEK) is a semi-crystalline organic thermoplastic composed from dialkylation of bisphenolate salts. This thermoplastic have excellent mechanical properties and can retained its properties up to temperature of 140°C. It is highly resistant to thermal degradation, and have good resistance to chemical of organic and aqueous contents. But the material can be attacked by halogenated compounds and aliphatic hydrocarbons at high temperatures. To be cautioned that PEEK will be completely dissolves in concentrated sulfuric acid even at room temperature.
