Rod PEEK

plateinsulating

PEEK is a semi-crystalline polymer with excellent mechanical and thermal properties (up to 240°C). It resists creep under load and wear, and has a relatively low friction coefficient. Heat resistance without load is high but significantly reduced under load, even if limited. Applications: Mechanical: High dimensional stability and wear resistance; used for high-performance parts in aerospace, automotive, and industrial applications. Electrical: Good dielectric and insulating properties. Chemical: Excellent chemical resistance. Nuclear: High gamma radiation resistance. PEEK presents the following properties: High temperature resistance: withstands up to 240°C (but resistance values are heat-sensitive). High resistance to gamma radiation. Excellent resistance to sterilization cycles. Very dimensionally stable. Good chemical resistance. Good abrasion resistance. Electrical insulation. EC 10/2011 food certification. However, there are some drawbacks: Very high cost. Load capacity decreases above 140°C. It is a technoplastic material not stable to UV. MECHANICAL ELECTRICAL CHEMICAL AEROSPACE PHARMACEUTICAL FOOD
