PPS
PPS is a semi-crystalline high-performance plastic for heat- and chemical-resistant components.
Select around heat, chemicals and the loaded features
Explain the working environment and the features carrying load when discussing PPS with Aria. Our material review can cover grade and reinforcement alongside the molded geometry and critical dimensions. Keep the specified formulation with the drawing; unfilled and reinforced PPS property values are not interchangeable.

Compatible manufacturing processes
Selection requirements
- CNC Milling Services · Injection molding · Precision CNC machining · CNC turning
Injection molding after drying, with supplied reference melt temperatures around 300–320°C and mold temperatures above 130°C. Limited CNC work is possible in suitable stock. Use appropriate reinforced grades for loaded components. Unfilled and reinforced HDT values differ substantially, so keep grade and load attached to each value.
Advantages and considerations
Advantages
Low moisture uptake, dimensional stability and chemical resistance. Suitable grades provide flame resistance and prolonged high-temperature performance.
Material limitations
Unfilled PPS is brittle. Natural colors tend toward brown, processing temperatures are high and cost exceeds general-purpose plastics.
How Aria supports your project
Help choosing a material
Compare materials for the loads, temperature and environment your part will face.
Design feedback before production
We review tool access, geometry and material choice before manufacturing.
Inspection to your drawing
Dimensional checks and inspection reports for the critical features on your drawing.
Compatible surface finishes
Selection requirements
- Laser engraving
Use appropriate reinforced grades for loaded components. Unfilled and reinforced HDT values differ substantially, so keep grade and load attached to each value. Laser marking and plasma treatment. Electroplating is generally unsuitable.
Applications
Typical applications
Heat-resistant automotive and electronic components, connectors, pump and valve parts, chemical-handling parts and precision structures.
Design considerations
Processing options
Injection molding after drying, with supplied reference melt temperatures around 300–320°C and mold temperatures above 130°C. Limited CNC work is possible in suitable stock.
Finishing options
Laser marking and plasma treatment. Electroplating is generally unsuitable.
Grade and finish combinations
Use appropriate reinforced grades for loaded components. Unfilled and reinforced HDT values differ substantially, so keep grade and load attached to each value.
Color and grade options
Natural light brown to brown. Black and other dark colors; light colors are limited.
Unfilled and glass-filled PPS
PPS grades are available for sustained high-temperature applications. Celanese describes Fortron continuous-use capability extending toward 240°C, but the allowable temperature depends on grade, loading, exposure and required lifetime. Fortron 1140L4 is a 40% glass-fiber-reinforced example; its stiffness and heat-deflection behavior must not be inferred from the unfilled 0205 data shown here. A heat-deflection result above 260°C for a reinforced grade is not a continuous-use rating.
