Polymaker Fiberon PPS-GF20

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 Lab AMS systems. Low moisture absorption (0.11%， 70%RH, 23°C) ensures reliable print quality, even in humid environments.
