PEEK-LCF20 Material Overview
PEEK-LCF20 is a high-performance thermoplastic reinforced with 20% long carbon fiber, designed for applications that require higher mechanical strength, dimensional stability, and chemical resistance. The increased long carbon fiber content enhances stiffness, wear resistance, and mechanical strength, while still retaining the excellent thermal and chemical properties of pure PEEK.
Mechanical Properties
PEEK-LCF20 offers superior mechanical performance compared to PEEK LCF10, making it suitable for applications that require higher strength and wear resistance, especially in more demanding environments.
Tensile Strength: ≥ 250 MPa
Flexural Strength: ≥ 450 MPa
Impact Strength: ≥ 4.0 kJ/m²
With 20% long carbon fiber reinforcement, PEEK LCF20 provides significantly improved stiffness, fatigue resistance, and dimensional stability compared to pure PEEK, making it ideal for high stress applications.
Thermal and Chemical Resistance
PEEK-LCF20 retains the excellent thermal and chemical resistance properties of pure PEEK, performing reliably under a wide range of temperatures and chemical exposures. The increased carbon fiber content has minimal impact on these key characteristics.
Heat Deflection Temperature (HDT): Approx. 340°C
Long-Term Service Temperature: Up to 270°C
Chemical Resistance: Excellent against oils, fuels, solvents, and aggressive chemicals
PEEK-LCF20 is ideal for industrial and automotive applications where both thermal and chemical resistance are crucial.
Wear Resistance and Processing
The 20% carbon fiber reinforcement further enhances wear resistance, making PEEK LCF20 suitable for applications with higher friction and stress. It also allows for more demanding mechanical environments while still offering reasonable processability.
Wear Resistance: Excellent under high friction and stress
Processing Methods: Suitable for injection molding and extrusion at temperatures similar to or slightly higher than those for PEEK LCF10
PEEK-LCF20 offers improved durability and wear resistance over pure PEEK, making it well suited for high performance applications.
Environmental Adaptability
PEEK-LCF20 exhibits low moisture absorption and excellent dimensional stability, ensuring reliable performance even under fluctuating temperature and humidity conditions.
Water Absorption: Low
Dimensional Stability: Excellent, even under varying temperature and humidity environments
Applications
PEEK-LCF20 is ideal for applications where high mechanical strength, thermal stability, and superior wear resistance are required, including:
Automotive: Structural components exposed to high mechanical loads, temperatures, and chemical environments
Industrial Manufacturing: High performance components like gears, bearings, bushings, and seals under intense wear and stress
Aerospace: Lightweight, high strength components for aircraft and spacecraft with high temperature resistance and dimensional stability
Electronics: Durable housings, connectors, and enclosures exposed to high mechanical stresses
Medical Devices: Biocompatible components requiring exceptional durability and resistance to sterilization processes
