Polymaker Fiberon™ PPS-GF20 Grey Filament

Fiberon™ PPS-GF20 Grey is a high-performance engineering filament based on polyphenylene sulfide (PPS), reinforced with 20% glass fiber. This advanced material delivers excellent mechanical strength, high thermal resistance, and outstanding chemical resistance, making it ideal for demanding industrial applications requiring precision and durability.

Key features

• 20% glass fiber reinforcement: Enhances stiffness, strength, and dimensional stability.
• High heat resistance: Suitable for applications exceeding 200 °C.
• Excellent chemical resistance: Resistant to fuels, solvents, acids, and bases.
• Low warping: Minimal shrinkage for high dimensional accuracy.
• Flame retardant: UL94 V0 rating (typical at thin wall thickness).
• Low moisture sensitivity: More stable than many other engineering polymers.

Technical specifications

Applications

Fiberon™ PPS-GF20 Grey is ideal for functional end-use parts, automotive components, electrical housings, tooling, and applications exposed to harsh chemicals or high temperatures. Its combination of strength, thermal resistance, and dimensional stability makes it suitable for demanding industrial use.

Note: The abrasive nature of glass fiber will wear standard nozzles quickly; a hardened nozzle is strongly recommended.
