PPA-CF20 Material Overview

PPA-CF20 is a high-performance engineering plastic developed for the most demanding industrial applications requiring exceptional mechanical strength, superior thermal stability, and excellent chemical resistance. With 20% carbon fiber reinforcement, PPA-CF20 offers significantly increased stiffness, strength, and dimensional stability compared to lower reinforcement grades, while maintaining good processability. This material is ideal for applications exposed to extremely high mechanical loads, elevated temperatures, and aggressive chemical environments.

Mechanical Properties

PPA-CF20 delivers outstanding mechanical performance, with significantly improved strength and stiffness, while maintaining processability. It is designed for high-load applications where maximum strength and dimensional stability are essential.

• Tensile Strength: ≥ 180 MPa (Enhanced by 20% carbon fiber reinforcement)
• Flexural Strength: ≥ 250 MPa
• Impact Strength: ≥ 15 kJ/m² (Improved over lower reinforced grades)

The 20% carbon fiber content offers substantial stiffness and strength, making PPA-CF20 suitable for the most demanding mechanical environments.

Thermal and Chemical Resistance

PPA-CF20 excels in extreme thermal and chemical environments, offering outstanding heat resistance and chemical stability.

• Heat Deflection Temperature (HDT): Approx. 280°C
• Long-Term Service Temperature: Up to 250°C
• Chemical Resistance: Excellent resistance to oils, fuels, solvents, and aggressive industrial chemicals

The higher carbon fiber content greatly enhances its heat resistance and stability, making PPA CF20 ideal for high temperature and chemically aggressive conditions.

Wear Resistance and Processing Characteristics

PPA-CF20 is well-suited for applications demanding exceptional wear resistance, especially under heavy friction or repetitive motion. Its higher carbon fiber content improves wear properties while maintaining manageable processing temperatures.

• Wear Resistance: Excellent under heavy friction and continuous motion
• Processing Methods: Suitable for injection molding and extrusion, with slightly higher processing temperatures than unreinforced PPA, but still within typical thermoplastic ranges

PPA-CF20 offers excellent durability and rigidity, perfect for applications requiring both wear resistance and ease of processing.

Environmental Adaptability

PPA-CF20 provides excellent environmental stability with very low water absorption, high dimensional stability, and reliable performance in both humid and chemically aggressive environments.

Applications

PPA-CF20 is designed for ultra-high-performance applications that require superior mechanical strength, thermal stability, and chemical resistance. Typical applications include:

• Automotive Industry: Engine components, high-strength housings, and structural parts exposed to extreme conditions.
• Industrial Manufacturing: Heavy-duty gears, bearings, structural components, and parts subjected to high mechanical loads and harsh chemicals.
• Aerospace: Critical components requiring high strength, lightweight properties, and high thermal resistance.
• Electronics: Enclosures and housings requiring superior strength, heat resistance, and dimensional stability.
• Consumer Goods: Durable parts for tools, appliances, and machinery exposed to high mechanical stress and chemicals.
