O-rings are round rings made of natural rubber or synthetic rubber elastic compounds. O-rings are widely used in industrial sectors from automotive to fluid power to semiconductor processing. Commonly used for automotive, construction equipment, heavy trucks, refrigeration and air conditioning components, commercial and military aircraft, pharmaceutical, oil and gas rigs, kitchen and bathroom fixtures, surgical instruments, fuel handling equipment and drug delivery equipment and more applications. The semiconductor production environment can represent some of the worst environments that O-ring seals may encounter, and the process can be varied from high temperature, corrosive plasma, unstable chemicals, etc. Semiconductor O- Rings are standard or custom made in traditional or premium recipes. Semiconductor O Rings and seals require high reliability, high purity, and must be highly resistant to chemical and thermal degradation. To solve unique problems, many seals have been developed by manufacturers in the semiconductor industry. Whether it\'s liquid or air flow, semiconductor O- The ring is very effective in making the seal efficient. The quality of the seals plays a vital role, and manufacturers must be extra careful when choosing raw materials and production processes. With high-tech solutions and advanced methods, the sealing devices available today are very satisfactory, offering ideal results every time the product is used for a wide range of industrial uses. Many critical manufacturing environments, such as semiconductor manufacturing and pharmaceutical processing, require sealed products with higher purity than standard industrial O-rings. Sealed products designed with strict UHP or ultra-high purity processes are ideal for such applications. UHP or ultra-high purity can reduce pollution, thus improving the normal operation time and performance of the equipment. The UHP process is carried out in a separate manufacturing unit, using equipment dedicated to the manufacture of high-quality fluorine rubber. This state-of-the- Art cell prevents contamination of materials from dust, mold spray, foreign matter, handling and other typical sources. From material formulation to final product packaging, measurement, evaluation, and statistical process control are carried out at every step of the UHP manufacturing process. The result is a product like a semiconductor o ring with unparalleled purity and consistency. Semiconductor O The ring is designed for use in harsh operating environments where excellent thermal stability, chemical resistance and ultra-high purity are required.
