Print Electrically Insulative, Flame-Retardant Parts with Fiberon™ PPS-GF20
Designed for engineers who demand the best in thermal resistance, dimensional stability, and dielectric insulation. This glass fiber–reinforced PPS filament is the go-to choice for high-performance applications across electronics, aerospace, and industrial environments.
Insulation Where It Matters
Fiberon PPS-GF20 offers 6.05 kV/mm dielectric strength and a low dielectric constant (2.71 @ 1MHz), making it perfect for electrical housings, ADAS sensor enclosures, and structural components in 5G base stations.
Built to Withstand Extreme Heat
Engineered to maintain structural integrity in temperatures up to 236.3 °C (HDT @ 0.45 MPa after annealing). Whether you're building parts for high-temp enclosures, hot-air equipment, or vehicle under-hood use, this filament won’t warp under pressure.
Glass Fiber–Reinforced for Strength
With 20% glass fiber reinforcement, PPS-GF20 delivers exceptional strength and stiffness—up to 4552 MPa Young’s modulus and 102 MPa bending strength in XY—ideal for brackets, antenna mounts, and chemically exposed parts.
Flame-Retardant & Chemically Resistant
UL94 V0 certified at 1.5mm and resistant to acids, bases, oils, and solvents. A trusted option for mission-critical environments such as chemical labs, factory floors, and automotive housings.
Precise, Reliable, Print-Ready
Supports high-speed printing (up to 250 mm/s) with minimal warping and stable Z-axis strength. Recommended for hardened steel nozzles. Available in neutral gray for reduced heat absorption and post-processing flexibility.
AMS Compatible, Moisture & Tangle Free
Delivered vacuum-sealed and neatly wound, this filament is compatible with Bambu AMS systems. Low moisture absorption (0.11%， 70%RH, 23°C) ensures reliable print quality, even in humid environments.

Technical Specifications
Everything you need before you hit print
- Use a high-temperature hotend capable of 310-350°C and a wear-resistant nozzle, such as hardened steel or ruby, because the reinforcement is abrasive.
- Keep the filament path free of sharp bends or tight turns because the filament may snap.
- Store and print under dry conditions (relative humidity below 20%); dry at 100°C for 10 hours if the filament is damp or surface moisture is present.
- Keep the cooling fan OFF and the chamber at room temperature. Reduce print speed within the recommended range of up to 250 mm/s for better print quality
- Anneal at 130°C for 10 hours when the annealed mechanical and thermal performance stated in the TDS is required.
- PolySupport for PA12 is the support material recommended for Fiberon PPS-GF20.

Like everything Polymaker makes, this glass fill PPS is top notch stuff. Arguably prints better than its CF equivalent.
In our compression tests done on a lock stand fixture,
Polymaker PPS-GF20 did better by 18% than PPS-CF10.
Parts were printed at 340noz, 110bed, 65chmbr. 100% infill and salt annealed with the (high load), gradual rise, hold, fall method. 230c peak hold for 2.5 hours.
These parts withstood 650lbs for 15 seconds with less than .2mm of deflection!
When we tested the parts under heat at 130c we felt so comfortable with the results that we're now saving over $2000/month by switching to 3d printed PPS-GF20 parts over the brass machined versions. Just wished I could print this material at 100c! With 20% GF I bet I could produce and even stronger tensile strength part for another application. Polymaker hit a home run with this. Very impressed!
