PEEK-LCF50 Material Overview
PEEK-LCF50 is an advanced high performance thermoplastic that is reinforced with 50% long carbon fiber, designed for extreme applications that demand unparalleled mechanical strength, exceptional dimensional stability, and outstanding chemical resistance. The higher carbon fiber content provides superior stiffness, enhanced wear resistance, and greater mechanical strength, all while preserving the outstanding thermal and chemical properties of pure PEEK.
Mechanical Properties
PEEK-LCF50 offers superior mechanical performance compared to PEEK-LCF40, making it the ideal choice for applications requiring even higher strength, wear resistance, and dimensional stability under the most demanding conditions.
Tensile Strength: ≥ 350 MPa
Flexural Strength: ≥ 600 MPa
Impact Strength: ≥ 2.8 kJ/m²
With a 50% long carbon fiber reinforcement, PEEK-LCF50 delivers exceptional stiffness, fatigue resistance, and dimensional stability, making it perfect for high stress applications and environments where extreme durability is crucial.
Thermal and Chemical Resistance
PEEK-LCF50 retains the outstanding thermal and chemical resistance characteristics of pure PEEK, with minimal effect from the higher carbon fiber content. This ensures reliable performance in harsh chemical environments and under extreme temperature conditions.
Heat Deflection Temperature (HDT): Approx. 370°C
Long-Term Service Temperature: Up to 280°C
Chemical Resistance: Excellent against oils, fuels, solvents, and aggressive chemicals
PEEK-LCF50 is particularly suited for industrial, automotive, and aerospace applications where both high thermal stability and resistance to aggressive chemicals are critical.
Wear Resistance and Processing
The 50% carbon fiber reinforcement greatly enhances wear resistance, making PEEK-LCF50 highly effective in applications exposed to high friction, abrasive environments, and stress. Despite its high reinforcement level, the material retains reasonable processability.
Wear Resistance: Superior under high friction and stress
Processing Methods: Suitable for injection molding and extrusion at temperatures slightly higher than for PEEK-LCF40
PEEK-LCF50 is an extremely durable material ideal for demanding high performance applications that require exceptional wear resistance and long term reliability.
Environmental Adaptability
PEEK-LCF50 exhibits low moisture absorption and exceptional dimensional stability, ensuring it performs reliably even in fluctuating temperature and humidity conditions.
Water Absorption: Low
Dimensional Stability: Excellent, even under varying temperature and humidity environments
Applications
PEEK-LCF50 is perfectly suited for demanding applications where superior mechanical strength, high thermal stability, and exceptional wear resistance are required, including:
Automotive: Structural components exposed to extreme mechanical loads, high temperatures, and aggressive chemicals.
Industrial Manufacturing: High performance components like gears, bearings, bushings, and seals subjected to intense wear and stress.
Aerospace: Lightweight, high strength components for aircraft and spacecraft requiring 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.
