Dollfus & Muller is using in PEEK in PEEK belts for printing dryer belts.
The Polyetheretherketone pointed out by the abbreviation PEEK (PolyEtherEtherKetone), is a polymer commercialised in 1978 by ICI.
The PEEK is a thermoplastic semi cristalline, thermostable with a high price. The PEEK is used for example to reinforce carbon fibre structures or the coating of mechanical pieces non lubricate, also for the surgical prosthesis.
• Density : 1.32
• Very resistant to the thermical degradation
• Temperature of glassy transition : 143 °C
• Fusion point : about 343 °C
• Excellent mechanical properties even at high temperature
• Young Module : 3.6 GPa
• Maximum constraint : 90 - 100 MPa
• Elongation : 50%
• Excellent chemical resistance even at high temperature
• Very resistant to the organic and aqueous environments and to solvents
• Moderately resistant to acids. The PEEK can be attacked by the halogens, the strong acids of Bronsted and Lewis as well as some composed halogens and aromatical hydrocarbures.
