Polymaker Fiberon PPS-GF20 Filament Grey 1.75mm 3KG Spool — Open-Box, 58% Off

Built for Extreme Heat: Withstands temps over 230 °C (HDT @0.45MPa), making it ideal for automotive, aerospace, and high-voltage enclosures exposed to continuous heat. Outperforms PA6-GF in thermal stability.

Electrically Insulating & Safe: Engineered with 20% glass fiber, PPS-GF20 delivers 6.05 kV/mm dielectric strength—making it perfect for housings, insulators, and ADAS components that require non-conductive materials.

Flame Retardant & Reliable: UL94 V0 certified at 1.5 mm with excellent mechanical retention after annealing. Ideal for applications where flame resistance is non-negotiable, including fan housings and control boxes.

Strong and Reliable: Reinforced with glass fiber to boost strength and rigidity. Achieves over 4,000 MPa bending modulus and 100+ MPa flexural strength—perfect for brackets, structural parts, and enclosures.

Exceptional Chemical Resistance: PPS-GF20 resists strong acids, bases, oils, and solvents—ideal for labs, industrial plants, aerospace fixtures and automotive parts exposed to harsh environments.

Print-Ready for Professionals: Supports speeds up to 250 mm/s with hardened nozzles. Easy to print on industrial machines like Bambu X1E or QIDI Plus4. Great for users upgrading from CF-based materials.

Excellent Dimensional Accuracy: Retains form after annealing—91.8 °C unannealed HDT becomes 236.3 °C after 130 °C/10h cycle. Minimal shrinkage, ideal for precision applications like sensor housings or mountings.

AMS-Compatible & Moisture Free: Vacuum-sealed and neatly wound for smooth feeding. Low moisture absorption (0.11%, 70%RH, 23°C) reduces warping, making it perfect for high-precision automated workflows.

Multiple Sizes for Scalable Production: Available in 0.5kg and 3kg spools to fit everything from trial runs to full-scale manufacturing—maximize throughput while reducing cost per part.

Trusted by Industrial Leaders: From aerospace fixtures to automotive radar housings and high-temp antenna mounts—PPS-GF20 delivers consistent results in mission-critical applications.

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 130°C 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 you're building functional prototypes or end-use parts, Fiberon PPS-GF20 combines strength and precision for the toughest industrial applications.
