Cost-Effective PPS Alternative to PEEK for Durable Industrial Components
Designed for applications requiring chemical resistance, dimensional stability, and improved durability at a lower cost than PEEK.
Unfilled PPS offers reliable machining performance and stable mechanical properties for demanding industrial environments where ultra-high temperature capability is not required.

What Unfilled PPS Offers
Performance characteristics that make Unfilled PPS suitable for chemically aggressive and high-temperature applications.
Improved Durability and Toughness
Enhanced toughness helps reduce brittleness and improve resistance to cracking, chipping, and handling damage compared to standard PPS.
Cost-Effective Alternative to PEEK
Provides many of the dimensional stability and chemical resistance benefits associated with high-performance polymers while offering a lower-cost solution for industrial applications that do not require PEEK-level temperature capability.
Excellent Chemical Resistance
Performs reliably in chemically aggressive environments exposed to fuels, oils, solvents, acids, and industrial process chemicals.
Reliable Machining Performance
Designed for stable machining behavior with improved resistance to edge chipping and cracking compared to more brittle PPS formulations.
Strong Dimensional Stability
Low moisture absorption and thermal stability help maintain tolerances during machining and operation.

Frequently Asked Questions
Choose PPS IM when chemical resistance and ease of machining are more important than maximum stiffness or load-bearing capability.
Unfilled PPS can serve as a cost-effective alternative to PEEK in applications where the higher continuous operating temperature capability of PEEK is not required.
No. Impact modification improves toughness and durability, but slightly reduces stiffness and rigidity compared to standard PPS or heavily glass-filled PPS grades
