PPS-CF is a carbon-fiber-reinforced polyphenylene sulfide engineered for high stiffness, dimensional stability, chemical resistance, and exceptional thermal performance. It is suited to specialized functional components operating in corrosive, high-temperature, or flame-exposure environments.
Design Advantages
High stiffness and dimensional stability for precision structural components
Exceptional heat-deflection and softening temperatures for extreme service
Very low water absorption for stable performance in humid environments
Broad resistance to acids, alkalis, solvents, oils, and greases

Design and Validation Considerations
Design for anisotropy: published strength, elongation, and impact performance are lower in the Z direction than in X/Y.
Use X/Y-oriented load paths where maximum strength, ductility, and impact performance are important.
Dry and store material below 20% RH with desiccant; moisture can affect extrusion quality and finished-part performance.
Higher chamber and nozzle temperatures can improve properties, especially in Z; validate the selected process window.
Annealing at 180 to 220 C for 6 to 12 h may change properties and can reduce toughness or cause deformation; validate the specific geometry and process.
Confirm chemical compatibility, sustained-temperature behavior, creep, flammability, and safety-critical loads in the intended service environment.
Published Data and Qualification
The values in this sheet are based on standardized specimen testing documented by the material source and are provided for design reference and material comparison. Lucent Additive has not independently generated every published value. Final-part performance can differ because of geometry, orientation, processing, moisture conditioning, and service environment. This document does not create a material warranty or replace qualification of the customer’s finished component.
