01 / Why choose this material
Properties and uses
of PPS.
Thermoplastic for components exposed to chemical agents and high temperatures. It features low moisture absorption and good dimensional stability.
PPS (phenylsulfone polymer) is a high-performance thermoplastic with low moisture absorption. It is used when dimensional stability and chemical resistance are critical. The grade and reinforcements determine thermal and mechanical performance.

Chemical equipment parts
Parts for chemical process equipment.
02 / A choice based on usage
Choose PPS
based on your part.
These criteria help define the material, geometry, and working conditions before manufacturing.
01
Unreinforced PPS
Family reference for machining. Confirm properties of the supply grade.
02
PPS + 30% GF
Glass fiber reinforcement changes stiffness and properties. Fiber orientation influences the part.
03
Agents and temperature
Specify fluid, concentration, temperature, and exposure. No universal thermal range is assigned to all PPS grades.
The part's function is the starting point.
Indicate loads, temperature, environment, and appearance needed. If the drawing requires a specific grade, include it in the request.
03 / Finishing also counts
Finishes and appearance
of PPS.
Material and process define the surface. These are the key factors for specifying your part's appearance.
Machining finish
The part retains machining marks. Indicate adjustment surfaces and visible faces on the drawing.
Geometry and surfaces
For functional surfaces, define roughness and tolerances in the drawing. Feasibility is reviewed based on grade and geometry.
Your part requirements
Include the expected appearance and usage conditions in your request to confirm the quote.
04 / From design to quote
CNC machining
of PPS.
Milling and turning allow manufacturing PPS parts from a block, plate, or bar. The tool removes material to obtain faces, cavities, drilled holes, and contours according to the design.
Send a 3D model per part in STEP or a native supported format: SLDPRT, X_T, X_B, IPT, CATPART, PRT, SAT, or 3DM. Attach a PDF drawing for threads, inserts, or specific tolerances. STL is accepted only for 3D printing.
Upload your file and request a quotePart tolerances
For dimensions without a specific tolerance, Proto&Go! applies ISO 2768-m. With a drawing, equivalent tolerances to IT11 can be assessed, depending on the geometry and requested dimensions. Attach the drawing and mark the functional surfaces.
Calculate a tolerance ↗Quantity and cost per part
In CNC, setup costs are distributed across the batch units. The final reduction depends on machining time and material.

Frequently asked questions
Before manufacturing
in PPS.
Properties, applications, and manufacturing: answers to prepare your request.
What is PPS and what properties does it have?
Thermoplastic for components exposed to chemical agents and high temperatures. It presents low moisture absorption and good dimensional stability. Continuous temperature must be confirmed for the specific grade, load, and duration. Fiber-reinforced variants have other properties. The added values are references from the published PDF; the supply grade and test may change them.
What parts can be manufactured in PPS?
We can manufacture valve components, insulators, and connectors, machined gaskets, and chemical equipment parts. CNC machining allows adapting the geometry to your 3D file. Define the loads, the environment, and the finish so we can review the application.
What data do I need to select a machined PPS grade?
Define working temperature, loads, and contact chemical agents. Indicate if the drawing requires unreinforced PPS or glass fiber. The specific grade and semi-finished product allow confirming properties for component calculations.
What changes between PPS and PPS with glass fiber?
Glass fiber modifies stiffness and dimensional stability, as well as other properties. A PPS GF30 should not be calculated using values from unreinforced PPS. Use the datasheet of the semi-finished product to be machined.
Can I choose PPS for a valve working in hot conditions?
It can be an option if the grade is compatible with the fluid, pressure, and temperature. Also indicate load, duration, and sealing requirements. The name PPS alone does not fix the admissible valve temperature.
How much does it cost to machine a PPS part?
The price of machining PPS depends on geometry, grade, tolerances, finish, and quantity. It includes material, preparation, and machining. Upload the 3D file to the Proto&Go! platform to receive a quote with cost and lead time.
What tolerances can I request for a PPS part?
For dimensions without a specific tolerance, Proto&Go! applies ISO 2768-m. With a drawing, equivalent tolerances to IT11 can be assessed, depending on the geometry and requested dimensions. Attach the drawing and mark the functional surfaces.
What file do I need to manufacture a PPS part?
Send a 3D model per part in STEP or a native supported format: SLDPRT, X_T, X_B, IPT, CATPART, PRT, SAT, or 3DM. Attach a PDF drawing for threads, inserts, or specific tolerances. STL is accepted only for 3D printing.
