Polymaker Fiberon PPS-GF20 Glass Fiber-Reinforced PPS Filament Print Electrically Insulative, Flame-Retardant Parts with Fiberon™ PPS-GF20Designed 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 MattersFiberon 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 HeatEngineered 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 StrengthWith 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 ResistantUL94 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-ReadySupports 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 FreeDelivered 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. Have a different application in mind?
