Best for
Unfilled
- Wafer-polishing retaining rings
- Circuit-board inspection fixtures
- Chemical valves and nozzles
- Under-hood fluid ducts
Carbon-filled
- Packaging-line gripper bodies
- Hot-air intake connectors
- Ride-height sensor brackets
Glass-filled
- Plasma-torch insulators
- Circuit-board carrier frames
- Insulating bushings
It also suits:
- Parts wetted by solvents
- Insulating parts in the glass-filled grade
Not the right choice for
- Impact or shock loads in the glass-filled grade
- Hot, loaded parts in the unfilled grade
- Contact with nitric or hydrochloric acid, chlorine, bromine or peroxide
PPS as a printed part
The quiet specialist. PPS resists almost every solvent, and unlike the nylons it barely absorbs water, so it keeps its dimensions in a damp environment.
Key properties
| Tensile strength | 50 MPa unfilled, 47 to 87 MPa carbon-filled, 57 to 64 MPa glass-filled |
|---|---|
| Heat deflection | 90 C at 0.45 MPa unfilled; 230 to 264 C at 0.45 MPa, 104 to 235 C at 1.80 MPa carbon-filled; 236 to 249 C at 0.45 MPa, 126 to 220 C at 1.80 MPa glass-filled, annealed |
| Flammability | UL94 V-0 at 1.5 mm |
| Water uptake | 0.03 to 0.11 percent |
What to use instead
- PPA (high-temp nylon) when the part sits at 150 C or below.
- PEEK when the requirement is above what PPS can hold.
- Polypropylene (PP) when chemical resistance at room temperature is the whole requirement.
The FDM material selector narrows the whole range by operating temperature, load, chemical exposure, and budget.
