Encapsulated O-Ring, as a sealing solution commonly used in industrial fields, has excellent sealing performance and durability.
1. Definition:
Encapsulated O-ring, referred to as Encapsulated O-Ring, is a high-performance O-ring whose surface is wrapped in polymer material to provide an additional layer of protection to improve its wear resistance, chemical corrosion resistance and High temperature resistance.
2. Structure:
Encapsulated O-rings usually consist of two parts: a polymer outer layer and an O-ring core. The polymer outer layer can be made of different materials, such as polytetrafluoroethylene (PTFE), polyethylene (PE), etc., to adapt to different application environments. The core of the O-ring seal is generally made of elastic materials that are resistant to high temperatures and chemical corrosion, such as fluororubber (FKM) or silicone rubber (VMQ).
3. Material selection:
The material selection of encapsulated O-ring seals critically affects its performance and scope of application. According to the operating temperature, medium environment and stress conditions required by the sealing ring, a combination of different materials can be selected to achieve the best sealing performance and durability.
4. Application fields:
Encapsulated O-rings are widely used in various industries and fields, including chemical industry, petroleum, food processing, pharmaceuticals, semiconductors, aerospace, etc. Its excellent corrosion resistance, high temperature resistance and sealing performance make it a key sealing component.
5. Advantages:
1. Good sealing performance: The structural design and material selection of the encapsulated O-ring seal give it excellent sealing ability, ensuring that gas, liquid or solid media will not leak or penetrate.
2. Chemical corrosion and wear resistance: The polymer outer layer provides additional chemical corrosion and wear resistance, increasing the service life and reliability of the encapsulated O-ring seal.
3. High temperature resistance: The core material of the encapsulated O-ring seal has excellent high temperature resistance and can maintain good sealing performance in high temperature environments.
4. Reduce friction and wear: The polymer material in the outer layer of the sealing ring reduces the contact pressure and friction with the accessories, thereby reducing wear and the risk of damage to the sealing ring.
