Bambu Lab PPS-CF Filament 1.75mm 750g

Description

PPS-CF is a composite material made from carbon fibre-reinforced polyphenylene sulfide. The combination of PPS resin and carbon fibre 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 specialised engineering plastic that meets the demands of unique and challenging applications.

Ultra-High Heat Resistance

PPS-CF boasts a heat deflection temperature of up to 264C under 0.45 MPa and can continuously operate at temperatures exceeding 200C. This significantly outperforms normal PA-CF materials, which have maximum temperatures around 190C and 120C. Its exceptional heat resistance ensures outstanding creep resistance, making PPS-CF ideal for demanding industrial environments and applications.

Heat Deflection Temperature / (0.45 MPa)	57	87	117	184	186	205	227	264

Superior Flame Retardancy

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.

Unmatched Mechanical Properties

Combining the stiffness of PPS polymers with the reinforcing power of carbon fibre, 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%

Solvent and Chemical Resistance

PPS-CF offers outstanding solvent and chemical resistance, second only to PTFE (Teflon). It remains virtually insoluble in any solvent below 200C 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.

Ultra-Low Water Absorption

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.
