Polymaker Fiberon PPS-GF20 Filament 1.75mm 0.5kg Spool, Extreme Heat Resistance, Electrically Insulating, UL94 V0 Flame Retardan

Industrial Strength Meets Electrical Insulation: Fiberon PPS-GF20 Fiberon PPS-GF20 is a high-performance 3D printing filament engineered for professionals who demand durability, precision, and reliability under extreme conditions. Reinforced with 20% glass fiber, it delivers enhanced mechanical strength, electrical insulation, and chemical resistance-all while maintaining excellent printability. Designed for mission-critical applications, PPS-GF20 is ideal for electronic housings, high-temperature fixtures, and automotive components. With a Heat Deflection Temperature (HDT) of up to 236.3 C (after 130C annealing), it withstands intense thermal loads without deforming. Unlike carbon fiber blends, this material is electrically insulating, making it a safer choice for use in enclosures, connectors, and insulation environments. Engineered for stability, this filament holds dimensional accuracy even in humid or corrosive environments. Its UL94 V0 flame retardancy, low dielectric constant (2.71 @1MHz), and moderate dielectric strength (6.05 kV/mm) make it suitable for high-frequency signal components such as radar housings, RF modules, and 5G base station insulators. Professionals in aerospace, automotive, and electronics manufacturing trust PPS-GF20 for its exceptional creep resistance, rigid structure, and superior surface finish. Whether youre building functional prototypes or end-use parts, Fiberon PPS-GF20 combines strength and precision for the toughest industrial applications.
