Polymaker Fiberon PPS-GF20 Filament – Glass Fibre Reinforced PPS 1.75mm
Polymaker Fiberon PPS-GF20 is a high-performance engineering-grade 3D printing filament made from polyphenylene sulfide (PPS) reinforced with 20% glass fibre. Designed for industrial and mission-critical applications, it combines exceptional heat resistance, electrical insulation, chemical resistance, flame retardancy, and dimensional stability in a material that remains surprisingly easy to print compared to many other ultra-high-performance polymers.
Key Benefits
Industrial-Grade Strength & Stiffness
20% glass fibre reinforcement delivers excellent rigidity, dimensional stability, and mechanical performance for structural and load-bearing applications. maintains its structural integrity in environments where most engineering plastics fail.
Excellent Electrical Insulation
Offers excellent dielectric strength and low electrical conductivity, making it ideal for electronic housings, sensor enclosures, electrical insulation components, and other applications where electrical safety and reliability are critical.
Outstanding Chemical Resistance
Resistant to oils, fuels, solvents, acids, and bases, making it well-suited for demanding industrial, automotive, and chemical-processing environments.
Low Moisture Absorption
PPS-GF20 absorbs very little moisture from the environment, helping maintain dimensional accuracy, mechanical properties, and print consistency over time.
Exceptional Dimensional Stability
The glass fibre reinforcement minimizes shrinkage and warping, ensuring precise, dimensionally stable parts even in demanding operating conditions.
Industrial-Grade Heat Resistance
Capable of continuous operation at elevated temperatures while maintaining mechanical strength and structural integrity, making it suitable for high-temperature applications.
Optimized for High-Speed Printing
Despite its advanced engineering properties, Fiberon™ PPS-GF20 can be printed at speeds of up to 250 mm/s, making it more manageable than many other high-temperature engineering materials.
