• Material Properties of Labyrinth Seal PEEK Material

• 
  
• Labyrinth seal PEEK material typically starts as a black powder and undergoes a special forming process. This unique material has a diverse range of outstanding properties that make it highly suitable for demanding sealing applications.

• I. Density - A Key Consideration

• 
  
• The density of PEEK carbon fiber reinforced plastic, which is an important variant in the PEEK family for labyrinth seals, is around 1.4 - 1.6 g/cm³. When carbon fibers are incorporated into PEEK, the density is slightly adjusted compared to pure PEEK. This density range of about 5% increase (when compared to some baseline PEEK materials) is a result of the high - density carbon fibers. The addition of carbon fibers not only modifies the density but also significantly enhances other properties. This optimized density contributes to the material's overall performance in labyrinth seal applications, providing a balance between weight and mechanical strength.

• Exceptional Wear Resistance

• PEEK carbon fiber reinforced plastic has outstanding wear - resistant characteristics. In labyrinth seal operations, where the seal is constantly in contact with moving components, this property is of utmost importance. The carbon fibers within the PEEK matrix act as reinforcement, reducing the rate of material removal during friction. This high wear resistance ensures that the seal can maintain its shape and function over long periods, minimizing the need for frequent replacements. For example, in high - speed rotating machinery, the PEEK carbon fiber - reinforced labyrinth seal can withstand the continuous rubbing against shafts, providing reliable sealing for extended service intervals.

• Superior Scratch Resistance

• The material also offers excellent scratch - resistant properties. Scratches on the surface of a labyrinth seal can disrupt the sealing mechanism and lead to leakage. The combination of PEEK's inherent toughness and the reinforcing effect of carbon fibers makes the material highly resistant to scratching. Even in environments where there may be small abrasive particles present, the PEEK carbon fiber - reinforced plastic can maintain a smooth surface, ensuring the integrity of the seal and preventing premature failure.
