Product Details
- 20% Glass Fiber Reinforced PPS: Fiberon PPS-GF20 combines polyphenylene sulfide with 20 wt% glass fiber for high rigidity, mechanical strength and dimensional stability. Designed for electrical housings, sensor enclosures, brackets, fixtures and industrial functional parts.
- High Heat Performance After Annealing: Printed specimens achieve an HDT of 236.3°C at 0.45 MPa and 125.8°C at 1.8 MPa after annealing at 130°C for 10 hours. Actual part performance varies with load, geometry, print settings and annealing conditions.
- Electrical Insulation and Chemical Resistance: Unlike carbon fiber composites, PPS-GF20 maintains electrically insulating properties, with a typical dielectric strength of 6.05 kV/mm. Its PPS base material is suitable for parts exposed to demanding chemical and industrial environments.
- High-Temperature Printing Requirements: Use an all-metal hotend capable of 310–350°C, an 80–90°C build plate and a wear-resistant nozzle. Keep the cooling fan off. A heated chamber is not required, and speeds up to 250 mm/s may be possible after calibration.
- Drying and Post-Processing: If the filament has absorbed moisture, dry it at 100°C for 10 hours and keep it below 20% relative humidity during storage and printing. Anneal printed parts at 130°C for 10 hours to obtain the stated heat performance. Keep the filament path smooth and direct.

Nozzle Compatibility
Glass fiber is abrasive and wears brass (and stainless) nozzles out of round, sometimes within a single spool. Use hardened steel or another wear resistant nozzle such as ruby or tungsten carbide. With hardened steel, start about 5 to 10°C hotter than you would with brass.
