PEI-CF20 Material Overview

PEI-CF20 is a high-performance thermoplastic reinforced with 20% carbon fiber, designed for applications requiring exceptional mechanical strength, superior dimensional stability, and outstanding chemical resistance. The increased carbon fiber content significantly enhances stiffness, wear resistance, and structural integrity, making PEI-CF20 ideal for the most demanding, high stress applications. This high reinforcement level delivers exceptional durability, while retaining the excellent thermal and chemical properties of pure PEI.

Mechanical Properties

PEI-CF20 is engineered for extreme mechanical performance and wear resistance. The 20% carbon fiber reinforcement offers superior stiffness, tensile strength, and flexural strength, making it suitable for applications exposed to very high mechanical loads.

Tensile Strength: ≥ 150 MPa

Flexural Strength: ≥ 250 MPa

Impact Strength: ≥ 3.5 kJ/m²

With its higher carbon fiber content, PEI CF20 provides excellent resistance to deformation, making it ideal for high load, high stress applications.

Thermal and Chemical Resistance

PEI CF20 retains the superior thermal and chemical resistance properties of pure PEI, with minimal impact from the carbon fiber reinforcement. This material is highly suited for environments exposed to extreme temperatures and aggressive chemicals, ensuring reliable performance in harsh industrial applications.

Heat Deflection Temperature (HDT): Approx. 250°C

Long-Term Service Temperature: Up to 250°C

Chemical Resistance: Excellent resistance to oils, fuels, solvents, and a broad range of chemicals.

PEI-CF20 is ideal for use in high-temperature and chemically challenging environments.

Wear Resistance and Processing

The 20% carbon fiber reinforcement in PEI CF20 offers superior wear resistance, making it suitable for applications exposed to intense friction or abrasive conditions. Despite its higher reinforcement, PEI CF20 remains highly processable using standard thermoplastic processing methods.

Wear Resistance: Exceptional under high friction and stress

Processing Methods: Suitable for injection molding and extrusion at temperatures similar to those used for pure PEI.

PEI-CF20 provides long-lasting durability without compromising ease of processing.

Environmental Adaptability

PEI-CF20 exhibits minimal moisture absorption and excellent dimensional stability, even in extreme environmental conditions such as varying temperature and humidity.

Water Absorption: Very low

Dimensional Stability: Excellent, even under fluctuating temperature and humidity.

This makes PEI CF20 a reliable material for use in a variety of environmental conditions, maintaining performance over time.

Applications

PEI-CF20 is designed for high duty, extreme performance applications that require superior mechanical strength, wear resistance, and chemical resistance. Common applications include:

Automotive: High performance components exposed to severe mechanical loads, vibrations, and high temperatures.

Industrial Manufacturing: Critical parts such as bearings, bushings, and electrical components exposed to extreme wear and stress.

Aerospace: Lightweight, high strength components for aircraft requiring excellent dimensional stability and high temperature performance.

Electronics: Housings, connectors, and enclosures exposed to significant mechanical stress and extreme thermal cycling.

Medical Devices: Biocompatible components requiring exceptional chemical resistance, stability under sterilization processes, and outstanding mechanical performance.
