Price of peek material11/6/2023 PEEK polymer is considered one of the highest performing materials in the world.Unlike many polymers, PEEK’s radiation resistance is quite high and it can absorb over 1000 units of radiation without any noticeable loss of its mechanical properties.What are the unique characteristics of PEEK Rod? : Surface roughening either may have some positive effect. This helps in other aspects of the materials performance in a positive way but is a disadvantage when it comes to adhesives. For bonding, we’d say to contact a specialist adhesive supplier but PEEK Rod is pretty difficult as it’s surface energy is very low.Because the stiffness of PEEK rod drops off significantly and its expansion rate increases above 150☌, an alternative material such as PAI (polyamide-imide) can be better choice for close tolerance bearings or seals operating at temperatures higher than 150☌.PEEK rod has excellent machine-ability, is flame retardant, and possesses excellent wear and slide properties. PEEK rod material is 53% harder than Acetal and has 36% more tensile strength than nylon 6, 6. When it comes to high temperature its short term operating temperature is 300☌ - 40 degrees more than PTFE – that’s 15% higher.PEEK is one of the few plastics compatible with vacuum applications. It is also used extensively in the aerospace, automotive, and chemical process industries. Because of its qualities, PEEK rod is used to fabricate items used in demanding environments, such as bearings, piston parts, pumps, and compressor plate valves.PEEK is not a shape memory polymer in that it does not have the ability to return from a temporary deformed state to its original shape by an external stimulus such as temperature change. The price factor usually limits its application to high value items. One big disadvantage is the relatively high price of PEEK which is can be four times the cost of PTFE.Excellent high temperature performance - high continuous service temperature use of 260☌.High resistant to attack by both organic and aqueous environments.Melting point of 343☌ (higher than the melting point of PTFE or PPS).PEEK rod is comprised of a semi crystalline thermoplastic known for its unique combination of properties.
