PEI-CF05 Material Overview

PEI-CF05 is an advanced, high-performance thermoplastic reinforced with 5% carbon fiber, designed for applications requiring a balanced combination of mechanical strength, dimensional stability, and chemical resistance. The low carbon fiber content enhances stiffness and wear resistance without significantly altering the intrinsic thermal and chemical properties of pure PEI. This makes PEI-CF05 a versatile material for industries where moderate strength, stability, and chemical resistance are key requirements.

Mechanical Properties

PEI-CF05 offers good mechanical performance for applications where moderate strength and wear resistance are required, compared to higher reinforcement levels like PEI-CF10. With 5% carbon fiber reinforcement, PEI-CF05 provides enhanced stiffness and dimensional stability for environments requiring durability without excessive reinforcement.

Tensile Strength: ≥ 95 MPa

Flexural Strength: ≥ 150 MPa

Impact Strength: ≥ 1.5 kJ/m²

With 5% carbon fiber reinforcement, PEI-CF05 delivers improved stiffness and resistance to deformation, making it suitable for light to moderate stress applications.

Thermal and Chemical Resistance

PEI-CF05 maintains the excellent thermal and chemical resistance properties of pure PEI, with minimal effect from the low carbon fiber content. This ensures dependable performance in moderate-temperature environments and against chemicals encountered in everyday industrial applications.

Heat Deflection Temperature (HDT): Approx. 170°C

Long-Term Service Temperature: Up to 170°C

Chemical Resistance: Excellent against oils, fuels, solvents, and a wide range of chemicals

PEI-CF05 is especially suited for applications where reliable performance is required under moderate temperatures and exposure to a variety of chemicals.

Wear Resistance and Processing

Although the carbon fiber content is low, PEI-CF05 offers enhanced wear resistance, making it ideal for applications where moderate friction or abrasive conditions are encountered. The material remains highly processable and easy to fabricate using standard methods.

Wear Resistance: Good under moderate friction and stress

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

PEI-CF05 is a durable, processable material suited for general industrial applications that require light to moderate wear resistance and long term stability.

Environmental Adaptability

PEI-CF05 demonstrates low moisture absorption and excellent dimensional stability, ensuring reliable performance even under varying temperature and humidity conditions.

Water Absorption: Low

Dimensional Stability: Good, even under fluctuating temperature and humidity

Applications

PEI-CF05 is designed for moderate duty applications requiring reliable mechanical strength, chemical resistance, and wear resistance. Common applications include:

Automotive: Components exposed to moderate mechanical loads and temperatures.

Industrial Manufacturing: Parts such as bearings, bushings, and electrical components exposed to light wear.

Aerospace: Low-weight, moderately strong components for aircraft requiring good dimensional stability.

Electronics: Housings, connectors, and enclosures exposed to moderate mechanical stress.

Medical Devices: Biocompatible components that require chemical resistance and stability under sterilization processes.
