The PEEK raw materials for sealing, especially those tailored for pump and valve applications, are of great significance in ensuring efficient and reliable operation in industrial settings. The special PEEK raw material for pump and valve seals is a key player in this domain.
The PEEK sealing raw materials, in the form of black particles, serve as the building blocks for creating high - performance seals. These particles are processed using transfer molding technology. This manufacturing method is crucial as it enables the transformation of the PEEK raw materials for sealing into large - sized thick - walled pipes. Transfer molding allows for precise shaping, ensuring that the final product meets the exacting requirements of pump and valve seal applications. The density of the PEEK raw materials for sealing, which is around 1.4 - 1.6 g/cm³, is maintained during this process. This density, which may show a slight variation of about 5% depending on factors like the specific grade and any additives, contributes to the material's overall performance. The relatively high density of these PEEK sealing raw materials is beneficial as it provides a balance between weight and mechanical strength, which is essential for seals that need to withstand mechanical stress.
Exceptional Strength and Rigidity
The PEEK raw materials for sealing exhibit outstanding mechanical properties. They possess a high tensile strength, enabling them to endure substantial mechanical loads. In pump and valve operations, where seals are often subjected to pressure differentials and mechanical stresses, this strength is vital. For example, in high - pressure pumps, the PEEK seal made from these raw materials needs to maintain its integrity under the force exerted by the fluid passing through the pump. The rigidity of the PEEK sealing raw materials also contributes to its ability to resist deformation, ensuring a precise fit and effective long - term performance. The density of the material plays a role here, as the closely - packed molecular structure associated with its density helps in providing this strength and rigidity.
Superior Wear Resistance
Wear resistance is one of the remarkable characteristics of the PEEK raw materials for sealing. In pumps and valves, the seals are in constant contact with moving parts or fluids that may contain abrasive particles. The PEEK sealing raw materials' wear resistance allows them to withstand these frictional forces without significant degradation. This property significantly extends the service life of the seals, reducing the frequency of replacements and minimizing downtime in industrial processes. For instance, in a slurry pump handling abrasive fluids, the PEEK seal made from these raw materials can withstand the continuous abrasion better than many other materials, maintaining its sealing performance. The density - related structure of the PEEK also contributes to its wear - resistant nature, as it can resist the abrasive forces more effectively.
Resistance to Corrosion
The PEEK sealing raw materials show excellent corrosion resistance. Pumps and valves are often used in environments where they come into contact with a wide range of chemicals, including acids, alkalis, and solvents. The molecular structure of PEEK, which is related to its density and overall composition, is highly stable, protecting it from chemical attack. This resistance to corrosion ensures that the seals made from PEEK do not deteriorate when exposed to these aggressive substances, making them suitable for use in industries such as chemical processing, petrochemicals, and pharmaceuticals.
High Temperature Resistance
PEEK is well - known for its high - temperature resistance, and the PEEK sealing raw materials used in pump and valve applications are no exception. In many pump and valve operations, the operating temperatures can be quite high. The PEEK sealing raw materials can maintain their mechanical and chemical properties even at elevated temperatures, up to around 260 °C continuously. This high - temperature resistance allows the seals to function effectively in applications such as hot oil pumps or high - temperature chemical reactors, where other materials might fail due to thermal degradation. The density - related properties of the PEEK raw materials for sealing also play a role in its thermal stability, as the dense molecular packing can help in maintaining the material's structure at high temperatures.
