PPS-CF40 Material Overview

PPS-CF40 (Polyphenylene Sulfide with 40% Carbon Fiber) is an advanced high-performance engineering plastic designed to meet the most demanding industrial needs. With 40% carbon fiber reinforcement, PPS-CF40 offers superior mechanical properties, including enhanced strength, stiffness, and dimensional stability. This material is specifically engineered for high-load, high-stress environments where durability, chemical resistance, and thermal stability are critical. PPS-CF40 excels in extreme conditions, making it ideal for applications in industries that require exceptional mechanical performance.

Mechanical Properties

PPS-CF40 is engineered for applications that require exceptional strength and stiffness, coupled with outstanding chemical resistance and dimensional stability. The 40% carbon fiber reinforcement elevates the mechanical performance, particularly in environments with high loads and stresses.

• Tensile Strength: ≥ 200 MPa
• Flexural Strength: ≥ 400 MPa
• Impact Strength: ≥ 50 kJ/m²

The higher carbon fiber content significantly improves rigidity, making PPS-CF40 suitable for structural components that are subjected to extreme mechanical stresses.

Thermal and Chemical Resistance

PPS CF40 is specifically designed to perform in high-temperature and chemically aggressive environments. It retains its stability and outstanding performance even under the most challenging conditions.

• Heat Deflection Temperature (HDT): Approx. 340°C
• Long-Term Service Temperature: Up to 280°C
• Chemical Resistance: Exceptional resistance to oils, solvents, acids, alkalis, and other aggressive chemicals.

The 40% carbon fiber content not only enhances mechanical strength but also ensures that PPS CF40 maintains excellent chemical resistance and dimensional stability under extreme temperatures and harsh chemical exposures.

Wear Resistance and Processing Characteristics

With the 40% carbon fiber content, PPS-CF40 offers excellent wear resistance, especially in applications involving high friction or repetitive motion. This material excels in conditions where wear and tear are critical factors.

• Wear Resistance: Superior performance under high friction conditions.
• Processing Methods: Compatible with injection molding, extrusion, and other thermoplastic processing techniques. Processing temperatures for PPS CF40 are higher than those for lower carbon fiber content grades but remain manageable within the range of PPS-based materials.

The carbon fiber reinforcement contributes to the material’s enhanced durability and rigidity, ensuring long-term performance in high-stress, high-abrasion applications.

Environmental Adaptability

PPS CF40 is ideal for a wide range of environmental conditions. It has minimal water absorption, excellent dimensional stability, and maintains its mechanical properties in outdoor, humid, or chemically aggressive environments.

Applications

PPS CF40 is suitable for a wide range of demanding applications requiring superior mechanical properties, thermal stability, and chemical resistance. These include:

• Automotive Industry: Components such as gaskets, seals, connectors, and structural parts exposed to extreme mechanical stress.
• Industrial Manufacturing: Heavy-duty gears, bushings, bearings, and other components subjected to high mechanical stress, high temperatures, and exposure to aggressive chemicals.
• Electronics: Structural parts for devices that require high chemical and thermal resistance, such as enclosures and housings.
• Aerospace: Critical components that need to withstand high temperatures, mechanical stress, and harsh chemical environments while maintaining dimensional stability.
