PEEK, Polyetheretherketone, is a semi-crystalline high-performance thermoplastic material with high strength and stiffness as well as high ductility. It exhibits great chemical resistance, excellent mechanical strength, good electrical insulation, dimensional stability, and exceptionally high temperature resistance. It is suitable for continuous use up to 260ºC and still retains its physical properties. It also possesses hydrolysis resistance to steam, water, and sea water at elevated temperatures. It is commonly used in aerospace, automotive, medical, high temperature electrical applications due to these properties.
- Outstanding Chemical Resistance:PEEK has good resistance to hydrolysis water and steam, alcohols, esters, alkaline solutions, oils, fats, and fuels…
- Good Insulation Properties:PEEK has high volume resistivity and surface resistivity. It retains insulating properties over wide temperature range.
- High Strength & Toughness
- Low Water Absorption
- Inherently Wear & Abrasion Resistance
semiconductor machinery components, aerospace parts, washers, bushings, bearings, seals, backup rings, syringes, endoscopes, medical implants, cervical cages, pump and valve components, vacuum wand handles, food processing machinery components…
