PPS-Solvay Ryton CF30
Sustaining extreme dynamic wear resistance, mechanical stiffness, and chemical inertness in harsh industrial and aerospace environments without adding weight requires a premier structural composite, which Syensqo’s Ryton CF30 (formerly Solvay) delivers through its 30% carbon fiber reinforced polyphenylene sulfide (PPS) matrix. Featuring an optimized density of 1.45 g/cm³ and a heat deflection temperature (HDT) of 265°C, this high-performance grade provides a massive tensile modulus of 21,000 MPa alongside inherent electrostatic dissipation (ESD). Jucheng Precision, under IATF 16949 and ISO 9001 frameworks, specializes in precision molding of Ryton CF30. Utilizing 5-axis CNC-machined S136 stainless steel toolings, we control its anisotropic shrink variables (0.1%-0.3%) to deliver dynamic sliding components verified by Zeiss CMM.

PPS-Solvay Ryton CF30 Tooling & Friction Control Guide
Molding an ultra-high performance carbon-fiber reinforced PPS like Ryton CF30 requires strict thermal boundaries and advanced PM-hardened molds to prevent wear:
Powder Metallurgy Hardened Tool Steel
30% short carbon fibers act as an aggressive grinding agent under high injection pressures and melt viscosity. Jucheng’s tooling division prevents gate and cavity erosion by using premium CPM powder metallurgy tool steels or hardened H13/S136 steel (HRC 54–56) with PVD ceramic coatings.
Managing Anisotropic Shrinkage & Warpage
Ryton CF30 shrinks exceptionally low along the flow (typically 0.10%) but higher perpendicular to the flow (0.30%). We conduct detailed Moldflow analysis during DFM to locate gates, ensuring uniform fiber orientation to prevent structural warping.
Pressurized Oil Mold Temperature Control
We maintain mold temperatures at 135°C–150°C (266°F to 302°F) using pressurized water heaters. High mold temperatures maximize surface gloss, reduce weld lines, and prevent surface carbon-fibers from floating, ensuring a smooth and non-fibrous finish.
Desiccant Drying Protocol (Hydrolysis Prevention)
PPS is highly sensitive to moisture at high melt temperatures. Wet molding results in rapid hydrolytic chain cleavage, causing severe splay, gas bubbles, and a major drop in impact strength. We desiccant dry Ryton CF30 resin at 120°C–140°C (248°F–284°F) for 3–4 hours, keeping moisture below 0.02%.
Key Application Fields for PPS-Solvay Ryton CF30
