PolyEtherEtherKetone (PEEK) is a high-performance engineering thermoplastic that offers chemical and water resistance while operate at higher temperatures. Peek Unfilled is a general-purpose grade that is unreinforced and offers the highest elongation and toughness of all PEEK grades. Unfilled PEEK is available in sheet and rod forms in multiple colors including: natural (a very light brown or tan) and black colors. Black PEEK is ideal for instrument components where aesthetics is 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.
Benefits of PEEK Unfilled
Maintains shape and physical properties under extremely high temperatures (480 degrees max operating temperature)
FDA approved for repetitive food contact
Resistant to harsh chemical environments
Minimal smoke and toxic-gas emissions
Additional formulations (i.e., glass-filled, mineral-filled, carbon-filled, bearing, and medical grades) and variants within these grades (FDA compliant, static dissipative, high temperature) are available to meet specific application demands. Contact an Emco Industrial Plastics representative who can help you choose the correct material to meet the needs of your application.
