JUTAIPPS® NA is an unfilled, natural beige polyphenylene sulfide rod manufactured for precision-machined components used in chemical processing, electrical equipment, semiconductor machinery, pumps, valves and industrial systems.
PPS is a semi-crystalline high-performance thermoplastic with excellent chemical resistance, very low moisture absorption, inherent flame resistance and reliable dimensional stability.
Compared with conventional engineering plastics such as PA, POM and PET, PPS provides better resistance to elevated temperatures, aggressive chemicals, moisture and long-term dimensional change.
JUTAIPPS® NA rods are available in diameters from Ø10 to Ø160 mm. Cut-to-length supply and custom CNC machining can be provided according to customer drawings or samples.
Natural PPS offers excellent resistance to many:
• Acids
• Alkalis
• Fuels
• Oils
• Coolants
• Hydrocarbons
• Industrial cleaning agents
• Chemical process fluids
Chemical compatibility must be confirmed according to the actual chemical, concentration, temperature, pressure, mechanical stress and exposure time.
PPS maintains useful mechanical strength and dimensional stability at temperatures beyond the practical range of many conventional engineering plastics.
The allowable continuous operating temperature of a finished component depends on mechanical load, chemical exposure, pressure, service duration and component geometry.
JUTAIPPS® NA has very low water absorption, helping machined components maintain dimensional accuracy in humid, wet and chemically exposed environments.
This makes PPS suitable for precision components where moisture-related swelling must be minimized.
PPS combines:
• Low moisture absorption
• Good creep resistance
• Low molding shrinkage
• Stable electrical properties
• Relatively low thermal expansion
• Reliable performance during thermal cycling
For tight-tolerance components, controlled annealing and staged machining may improve final dimensional stability.
Unfilled PPS provides high volume resistivity, good dielectric strength and stable electrical insulation performance across a wide temperature range.
It is suitable for insulating bushings, electrical supports, connector components, sensor parts and high-temperature electrical assemblies.
PPS is inherently flame-resistant and can achieve UL94 V-0 performance under applicable grade and thickness conditions.
The final flame rating must be confirmed according to the selected resin, product thickness and finished component requirements.
PPS rod can be machined by:
• CNC turning
• Milling
• Drilling
• Grinding
• Threading
• Boring
• Cut-to-length processing
Sharp tools, stable clamping and suitable cooling should be used to minimize cutting heat and dimensional movement.
