When the operating environment exceeds 200°C or requires frequent steam sterilization, standard plastics fail. PEEK and PPSU are the two dominant materials in the medical and semiconductor industries. JSLT Polymers® (Factory Direct) provides a side-by-side technical analysis to justify the material cost.
1. PEEK: The 250°C Performance Benchmark
With a continuous service temperature of 250°C and excellent wear resistance, PEEK is the gold standard for semiconductor test sockets and surgical instrument handles. It remains chemically inert to almost all organic and inorganic chemicals.
2. PPSU: The Autoclave Specialist
While PEEK is stronger, PPSU (Polyphenylsulfone) offers virtually unlimited steam sterilization cycles without losing its impact strength. This makes it the ideal choice for medical trays and sterilization boxes.
❓ Frequently Asked Questions
❓ Is your PEEK FDA compliant?
Yes, we supply food-grade and medical-grade PEEK that meets FDA, EU 10/2011, and USP Class VI standards.
❓ Can you manufacture thin PPSU sheets?
We stock PPSU sheets from 5mm to 50mm, and can CNC machine them into thin-walled components.
