PPS-CF20 Material Overview

PPS-CF20 (Polyphenylene Sulfide with 20% Carbon Fiber) is a high-performance engineering plastic that combines the exceptional properties of PPS with 20% carbon fiber reinforcement. This increased carbon fiber content results in even greater strength, stiffness, and dimensional stability, while maintaining excellent chemical resistance and thermal stability. PPS-CF20 is specifically designed for demanding industrial applications that require high load-bearing capacity and long-term durability, making it an ideal material for extreme environments where performance is critical.

Mechanical Properties

PPS-CF20 is tailored for applications that require outstanding stiffness and strength, as well as excellent chemical resistance and dimensional stability. With double the carbon fiber content compared to PPS-CF10, it delivers superior mechanical performance for high-load and high-stress applications.

• Tensile Strength: ≥ 150 MPa
• Flexural Strength: ≥ 300 MPa
• Impact Strength: ≥ 50 kJ/m²

The 20% carbon fiber content greatly enhances the material’s rigidity, making PPS-CF20 perfect for structural components under extreme mechanical stress.

Thermal and Chemical Resistance

PPS-CF20 excels in high-temperature and chemically aggressive environments, ensuring long-term stability and reliable performance under the most demanding conditions.

• Heat Deflection Temperature (HDT): Approx. 300°C
• Long-Term Service Temperature: Up to 250°C
• Chemical Resistance: Outstanding resistance to oils, solvents, acids, alkalis, and other aggressive chemicals.

The higher carbon fiber content further enhances the material’s strength and dimensional stability, while maintaining its excellent resistance to chemicals, making it suitable for the toughest industrial environments.

Wear Resistance and Processing Characteristics

PPS-CF20 provides superior wear resistance compared to lower carbon fiber reinforced versions, making it ideal for components exposed to heavy abrasion or repetitive motion.

• Wear Resistance: Exceptional performance under high friction conditions.
• Processing Methods: Compatible with injection molding, extrusion, and other typical thermoplastic processing methods. Due to the higher carbon fiber content, processing temperatures are slightly higher than for PPS-CF10 but still within manageable limits for PPS-based materials.

The increased rigidity from the 20% carbon fiber reinforcement allows PPS-CF20 to maintain excellent durability while performing exceptionally well in challenging applications.

Environmental Adaptability

PPS-CF20 performs excellently in various environmental conditions, with minimal water absorption and outstanding dimensional stability. It remains highly reliable even in humid, outdoor, or chemically aggressive environments.

Applications

PPS-CF20 is ideal for demanding, high-duty applications that require superior mechanical properties, exceptional chemical resistance, and outstanding thermal stability:

• Automotive Industry: High-performance components like gaskets, seals, and connectors exposed to extreme stress.
• Industrial Manufacturing: Heavy-duty gears, bushings, and components subjected to high mechanical loads and harsh chemicals.
• Electronics: Structural parts for devices requiring top-tier chemical, thermal, and wear resistance.
• Aerospace: Critical components requiring high strength, dimensional stability, and performance under extreme thermal conditions.
