Polymaker Fiberon™ PPS-GF20 1.75 mm / 500g / Grey

• Industrial-grade strength
• high heat resistance
• V0 FR for the best insulation

Fiberon™ PPS-GF20 is a 20% glass fiber-reinforced polyphenylene sulfide filament engineered to deliver enhanced mechanical strength and dimensional stability. This advanced material maintains electrical insulation properties while achieving UL94 V0 Flame Retardance (1.5mm). Its inherent chemical resistance ensures reliable performance in demanding automotive, electronics, and industrial applications.

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.

Printing Requirements

• All-metal hotend 310˚C+
• Hardened nozzle
• Annealing post printing
• You may need a filament dryer depending on the humidity of your environment. Keep dry when not in use.
