High-Temperature PPS/PEEK Plastic Screws Extreme Condition Fasteners
High-Temperature PPS/PEEK Plastic Screws Extreme Condition Fasteners
PPS (Polyphenylene Sulfide) and PEEK (Polyetheretherketone) are high-performance engineering plastics capable of continuous operation at 200℃–260℃. With excellent acid/alkali resistance, organic solvent resistance, high insulation, low smoke and high strength, they are the top choice for non-metallic fasteners in chemical, medical, semiconductor, aerospace and food machinery applications.
Material Comparison: PPS vs PEEK
- PPS: Continuous temp 200–220℃, good chemical resistance, cost-effective
- PEEK: Continuous temp 250–260℃, extreme chemical resistance, high strength
Key Performance
- Ultra-high temperature resistance: PPS≈220℃, PEEK≈260℃
- Extreme corrosion resistance: Resists strong acids, alkalis and solvents
- High insulation: High breakdown voltage for high-frequency applications
- High strength: Metal-like strength, good creep and fatigue resistance
- Low smoke & non-toxic: UL94 V-0 flame rating, safe at high temperatures
Applications
- Chemical equipment: Reactors, plating tanks, acid/alkali pipes, valves
- Medical devices: Autoclave equipment, surgical instruments, sterile devices
- Semiconductor: Wafer carriers, cleanroom equipment, high-temperature jigs
- Aerospace: Lightweight structures, high-temperature cabin components
- Food machinery: High-temperature cooking and baking equipment parts
