PPS-CF 750g filament by Qidi tech PPS-CF is a composite material made from carbon fiber-reinforced polyphenylene sulfide (PPS). The combination of PPS resin with carbon fiber imparts excellent properties to PPS-CF, including outstanding solvent resistance, corrosion resistance, heat resistance, and flame retardancy. Additionally, higher printing temperatures enhance the strength, rigidity, and dimensional stability of PPS-CF. When paired with the QIDI Plus4, it becomes a specialty engineering plastic capable of meeting the demands of unique and challenging applications.
