PEEK and Other High-Temperature Material Selection
Problembeschreibung
【Problem Phenomenon】Selection among PEEK, PEKK, PI, and PPS wavers, and cost and performance are difficult to balance
Ursachenanalyse
PEEK has balanced comprehensive performance but high price; PPS has low cost and can cover some applications; PEKK has slightly higher temperature resistance; PI has the highest temperature resistance but limited processing; select materials according to needs to avoid excess performance
Lösung
Select PEEK for comprehensive working conditions below 260℃; verify PPS for cost-sensitive applications where performance meets standards; evaluate PEKK or PI above 260℃; establish a material selection decision matrix
Wichtigste Erkenntnis
PEEK selection guards against excess performance; PPS and PEKK each have their substitution ranges; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
