Eryone PPS-CF10 Carbon Fiber 0.5KG

Description

One of the Highest-Performance FDM Filaments Available

Eryone PPS-CF10 is a 10% carbon fibre reinforced polyphenylene sulphide filament built for applications where standard engineering filaments can’t survive. With a heat deflection temperature of 238°C at 0.45 MPa (post-annealing), inherent chemical resistance to fuels, solvents, and acids, and UL94 V-0 flame retardancy, PPS-CF10 produces production-grade parts that perform in environments that would destroy PETG, nylon, or ABS.

This is not an everyday filament. It requires a printer capable of 300°C+ nozzle temperatures, a heated bed at 100–120°C, and ideally an enclosed chamber. But if your application demands it, nothing else in the FDM filament range comes close.

Why PPS-CF Over Other Engineering Filaments?

Every engineering filament has trade-offs. PPS-CF10 sits at the top of the FDM performance ladder because it combines properties that no single alternative can match.

Compared to PA-CF (nylon carbon fibre): PPS-CF10 has far higher heat resistance, inherent chemical resistance without coatings, significantly lower moisture absorption, and does not require the same level of drying vigilance.

Compared to PETG-CF: PPS-CF10 operates at temperatures more than three times higher and resists chemicals that would dissolve PETG.

Compared to PC-CF (polycarbonate carbon fibre): PPS-CF10 offers superior chemical resistance and flame retardancy, with comparable mechanical stiffness.

The carbon fibre reinforcement adds stiffness, reduces thermal expansion, and produces a professional matte finish.

Key Properties

Heat deflection temperature: 238°C at 0.45 MPa (post-annealing)
Flame retardancy: UL94 V-0 rated
Chemical resistance: inherently resistant to fuels, solvents, acids, and alkalis
Moisture absorption: extremely low — minimal drying issues compared to nylon
Dimensional stability: excellent — low shrinkage and low coefficient of thermal expansion
Surface finish: matte carbon fibre texture

Applications

PPS-CF10 is suited to high-stress, high-temperature end-use parts where other filaments would fail. Common applications include automotive under-bonnet components — brackets, ducting, sensor housings, and heat shields that operate near engines and exhaust systems. Aerospace jigs, fixtures, and tooling that need dimensional stability at elevated temperatures. Chemical-resistant enclosures and housings for industrial equipment. Electrical and electronic components requiring UL94 V-0 flame retardancy. Functional prototypes that must survive real-world thermal and chemical exposure during testing.

Print Settings

PPS-CF10 is an advanced material that requires specific printer capabilities and careful setup.

Nozzle temperature: 300–320°C — requires a printer with an all-metal hotend rated for these temperatures
Bed temperature: 100–120°C — PEI or garolite bed surface recommended for adhesion
Enclosure: strongly recommended to prevent warping and layer delamination
Nozzle: hardened steel, 0.4 mm minimum, 0.6 mm recommended — carbon fibre will rapidly destroy brass nozzles
Print speed: 30–60 mm/s for best results
Drying: 80°C for 4–6 hours before printing — store in an airtight container with desiccant when not in use

Post-Print Annealing

PPS-CF10 reaches its maximum heat performance after annealing — a controlled heat treatment process that increases crystallinity and raises the heat deflection temperature to 238°C. Without annealing, the heat deflection temperature is lower. Annealing conditions vary by part geometry and wall thickness — start at 200°C for 1–2 hours and adjust based on results. Parts may experience slight dimensional changes during annealing, so account for this in your design.
