PolyEtherEtherKetone (PEEK), a high performance engineering thermoplastic, offers chemical and water resistance similar to PPS (PolyPhenylene Sulfide), but can operate at higher temperatures.
The general purpose grade is unreinforced and offers the highest elongation and toughness of all PEEK grades. Unfilled PEEK is available in sheet and rod forms in natural (a very light brown or tan) and black colors. Black PEEK is ideal for instrument components where aesthetics are important, as well as for seal components where ductility and inertness are important. All unfilled PEEK grades comply with FDA regulation 21 CFR 177.2415 for repeated food contact.The addition of glass fiber and carbon fiber reinforcements enhances the mechanical and thermal properties of the basic PEEK material.
