PPS in CNC Machining
Polyphenylene Sulfide (PPS) is a high-performance thermoplastic. Its exceptional mechanical properties, chemical resistance, and thermal stability make PPS a preferred material for CNC machining applications. PPS’s robustness and ability to withstand harsh environments enable the creation of reliable and durable components. Its resistance to chemicals and high temperatures, coupled with excellent dimensional stability, allows for precision in manufacturing complex parts. Additionally, PPS’s electrical insulating properties make it an ideal choice for electronic components, while its low moisture absorption ensures consistent performance over time.

Surface Finishing Options for PPS Machined Parts
RapidDirect offers a wide range of surface finishing options to enhance the functionality and aesthetics of your CNC machined PPS parts. Our finishes ensure that your components meet all necessary specifications and performance criteria.
As machined
PPS has a naturally smooth, clean finish right off the CNC machine, making it ready for use without additional finishing in many cases.
Sand Blasting
Effective for creating a matte texture, sandblasting can give PPS a uniform appearance, especially when a non-glossy finish is desired.
Tumbling
Suitable for removing small burrs and smoothing edges, tumbling enhances the aesthetic without compromising PPS’s durability.
Teflon Coating
Teflon can be applied for low-friction or non-stick properties, which is beneficial in high-wear or sliding applications, with proper surface prep.
Painting
PPS can be painted for color customization or added surface protection, provided there’s careful surface preparation.

FAQs
PPS is a semi-crystalline high-performance engineering thermoplastic known for its exceptional chemical resistance, thermal stability, and mechanical strength. It is commonly used in demanding applications that require durability and reliability under harsh conditions. PPS is particularly valued for its ability to maintain its properties at elevated temperatures and in chemically aggressive environments.
Machining PPS differs significantly from machining metals due to its lower density and different mechanical properties. PPS requires specialized tools and techniques to achieve precise results without damaging the material. Compared to injection molding, CNC machining PPS offers greater flexibility for producing complex geometries and low-volume parts without the need for expensive molds. Unlike 3D printing, CNC machining provides superior surface finishes and dimensional accuracy for PPS components.
PPS is considered suitable for machining due to its high strength, thermal stability, and excellent chemical resistance. These properties make it ideal for producing components that must withstand extreme environments and rigorous use. Additionally, PPS’s low moisture absorption and dimensional stability ensure consistent performance, making it a reliable choice for precision parts. Its electrical insulating properties further enhance its suitability for electronic and electrical applications.
