PPS-CF is a composite material made from carbon fiber-reinforced polyphenylene sulfide. The combination of PPS resin and carbon fiber gives PPS-CF exceptional properties, including excellent resistance to solvents, corrosion, heat, and flames. Additionally, it offers superior strength, stiffness, and dimensional stability, making it a specialized engineering plastic that meets the demands of unique and challenging applications.
PPS-CF boasts a heat deflection temperature of up to 264°C under 0.45 MPa and can continuously operate at temperatures exceeding 200°C. This significantly outperforms normal PA-CF materials, which have maximum temperatures around 190°C and 120°C. Its exceptional heat resistance ensures outstanding creep resistance, making PPS-CF ideal for demanding industrial environments and applications.

PPS-CF achieves a UL-94 V-0 flame retardant rating, offering superior safety and reliability in critical areas such as electronics and automotive components. PPS-CF provides long-lasting durability and peace of mind even in the most demanding environments.
Combining the stiffness of PPS polymers with the reinforcing power of carbon fiber, PPS-CF offers exceptional stiffness, bending strength, and tensile strength. Its superior dimensional stability and resistance to warping ensure that large-scale prints maintain precision and avoid deformation during the printing process, making it perfect for high-precision applications.
| PET-CF | PPS-CF | Improved % | |
| Stiffness (Bending Modulus - XY, Dry State) | 5320 MPa | 7160 MPa | 34.59% |
| Strength (Bending Strength - XY, Dry State) | 131 MPa | 142 MPa | 8.40% |
PPS-CF offers outstanding solvent and chemical resistance, second only to PTFE (Teflon). It remains virtually insoluble in any solvent below 200°C and exhibits exceptional resistance to acids, bases, and salts under normal conditions. This makes PPS-CF the ideal choice for challenging environments where chemical stability is critical.
With an extremely low moisture absorption rate of just 0.05%, PPS-CF ensures that its mechanical and thermal properties remain stable even in humid conditions. Unlike normal PA-CF, which can soften and degrade when exposed to moisture, PPS-CF maintains its strength and durability, making it the superior option for applications requiring high moisture resistance.

Bambu PPS-CF Printing Guidelines:
Drying Recommendations:
In a blast drying oven: 100°C to 140°C for 8 to 12 hours.
On an X1 printer's heatbed: 110°C to 120°C for 10 to 12 hours (less effective than a blast drying oven).
