PEI-CF30 Material Overview

PEI-CF30 is an advanced high-performance thermoplastic reinforced with 30% carbon fiber, designed for applications that demand exceptional mechanical strength, extraordinary dimensional stability, and superior chemical resistance. The higher carbon fiber content significantly improves stiffness, wear resistance, and structural integrity, making PEI-CF30 ideal for the most extreme, high-stress applications. This reinforced material delivers unparalleled durability, while preserving the excellent thermal and chemical properties of pure PEI.

Mechanical Properties

PEI-CF30 is engineered for extreme mechanical performance and wear resistance. With 30% carbon fiber reinforcement, it provides exceptional stiffness, tensile strength, and flexural strength, making it suitable for applications subjected to extremely high mechanical loads.

Tensile Strength: ≥ 170 MPa

Flexural Strength: ≥ 300 MPa

Impact Strength: ≥ 4.5 kJ/m²

The high carbon fiber content in PEI-CF30 ensures outstanding resistance to deformation, making it ideal for high load, high stress applications that require superior mechanical performance.

Thermal and Chemical Resistance

PEI-CF30 retains the superior thermal and chemical resistance properties of pure PEI, with minimal impact from the carbon fiber reinforcement. It performs exceptionally well in environments exposed to extreme temperatures and aggressive chemicals.

 Heat Deflection Temperature (HDT): Approx. 270°C

Long-Term Service Temperature: Up to 270°C

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

PEI-CF30 is perfect for high-temperature and chemically demanding environments where durability and stability are critical.

Wear Resistance and Processing

The 30% carbon fiber content in PEI-CF30 significantly enhances its wear resistance, making it suitable for applications exposed to extreme friction or abrasive conditions. Despite the higher reinforcement, it remains highly processable through standard thermoplastic processing methods.

Wear Resistance: Outstanding under very high friction and stress

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

PEI-CF30 offers long-lasting durability without sacrificing ease of processing, making it ideal for demanding industrial applications.

Environmental Adaptability

PEI-CF30 exhibits minimal moisture absorption and excellent dimensional stability, even in the most extreme environmental conditions, including temperature and humidity fluctuations.

Water Absorption: Extremely low

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

This ensures reliable performance in a variety of challenging environmental conditions.

Applications

PEI-CF30 is designed for extreme-duty applications that require top tier mechanical strength, wear resistance, and chemical resistance. Typical applications include:

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

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

Aerospace: Lightweight, ultra-strong 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 needing superior chemical resistance, high stability under sterilization, and outstanding mechanical performance.
