Application of food grade PEEK sealing rings in the food infusion industry
our mold design and injection service
1. the safety of food grade peek material
-Food grade PEEK sealing rings are made of PEEK material that meets food contact safety standards. This material has the characteristics of being non-toxic and odorless, and will not release harmful substances into food, meeting strict food safety regulations. Our food grade PEEK material has been certified according to FDA (US Food and Drug Administration) regulations for food contact materials, ensuring safety during the food infusion process.
2. Chemical corrosion resistance
-In the food infusion industry, sealing rings come into contact with various chemical substances such as food ingredients, additives, and cleaning disinfectants. PEEK sealing rings have excellent chemical corrosion resistance and can withstand most acidic, alkaline, and organic solvents. For example, when pouring fruit juice (acidic), dairy products (containing various components such as protein), and cleaning equipment with disinfectants, PEEK sealing rings can maintain good chemical stability and prevent corrosion and failure.
3. High temperature resistance performance
-During the process of food infusion, high-temperature treatment is often required, such as pasteurization, high-temperature sterilization, etc. PEEK sealing rings can maintain stable performance at high temperatures, and their long-term use temperature can reach around 260 ℃. In these high-temperature process steps, PEEK sealing rings will not soften or deform, ensuring the sealing performance of the equipment and effectively preventing food leakage and the entry of external impurities.
4. Mechanical performance and sealing effect
-PEEK material has good mechanical properties, including high strength and elastic modulus. This enables food grade PEEK sealing rings to maintain good elastic recovery ability when subjected to pressure and mechanical vibration from infusion equipment, ensuring sealing effectiveness. Its compression permanent deformation rate is relatively low, generally below 30%, which can maintain a sealed state for a long time and reduce the frequency of equipment maintenance and seal ring replacement.
5. Wear resistance and service life
-Due to the relative motion and friction between the sealing ring and the sealing surface of the food infusion equipment during operation, the wear resistance of PEEK sealing rings is particularly important. It has good wear resistance and can reduce material loss caused by friction, thereby extending its service life. Usually, under normal operating conditions of infusion equipment, the service life of food grade PEEK seals can reach several times that of ordinary rubber seals, reducing production costs and equipment downtime.
6. Example of application scenarios
-In the beverage infusion production line, food grade PEEK sealing rings are widely used in key parts such as valves and pipeline connections of filling machines to ensure the sealing and hygiene of beverages during the infusion process. In the infusion equipment of food sauces (such as tomato sauce, jam, etc.), PEEK sealing rings can also effectively resist the corrosion of sauces, ensuring precise infusion of sauces and clean maintenance of equipment.
