PPA-LCF40 Material Overview

PPA-LCF40 is a high-performance engineering plastic designed for demanding industrial applications that require exceptional mechanical strength, thermal stability, and chemical resistance. With 40% carbon fiber reinforcement, PPA-LCF40 offers significantly improved stiffness, strength, and dimensional stability compared to lower carbon fiber grades. This material is ideal for applications subjected to heavy mechanical loads, elevated temperatures, and harsh chemical environments.

Mechanical Properties

PPA-LCF40 provides superior mechanical performance, with enhanced strength and stiffness, making it ideal for heavy-duty industrial applications. The 40% carbon fiber reinforcement offers a substantial improvement over lower carbon fiber content grades, ensuring high reliability under demanding conditions.

• Tensile Strength: ≥ 400 MPa (Enhanced by 40% carbon fiber reinforcement)
• Flexural Strength: ≥ 600 MPa
• Impact Strength: ≥ 4.0 kJ/m² (Optimized for higher reinforcement levels)

The 40% carbon fiber content significantly increases the material’s stiffness and strength, making PPA LCF40 suitable for applications where robust mechanical performance is essential.

Thermal and Chemical Resistance

PPA LCF40 exhibits excellent thermal and chemical stability, capable of withstanding more extreme operating conditions than materials with lower fiber content. Its enhanced properties make it well suited for high-temperature and chemically aggressive environments.

Heat Deflection Temperature (HDT): Approx. 300°C

Long-Term Service Temperature: Up to 250°C

Chemical Resistance: Excellent resistance to oils, fuels, solvents, and many aggressive industrial chemicals

The 40% carbon fiber content further enhances the material’s heat resistance, dimensional stability, and chemical resilience, making it ideal for high performance applications in challenging environments.

Wear Resistance and Processing Characteristics

PPA LCF40 offers enhanced wear resistance, especially for components subjected to high friction, continuous motion, or long term stress. The increased carbon fiber reinforcement improves wear resistance while maintaining processability at higher temperatures than non reinforced grades.

Wear Resistance: Excellent under high friction and continuous motion

Processing Methods: Suitable for injection molding and extrusion, with processing temperatures higher than non reinforced grades but still manageable within typical thermoplastic processing ranges

PPA LCF40 is ideal for applications requiring high wear resistance and durability, coupled with ease of processing.

Environmental Adaptability

PPA LCF40 offers excellent environmental stability, with minimal water absorption, exceptional dimensional stability, and reliable performance in high humidity and chemically aggressive environments.
