Can extruded rubber profiles be used in vacuum applications?
Can extruded rubber profiles be used in vacuum applications? This is a question that frequently arises in various industries where precise environmental controls and reliable component performance are paramount. In my role as a supplier of extruded rubber profiles, I've encountered this query numerous times, and I'm eager to share an in - depth analysis of the topic.
Understanding Extruded Rubber Profiles
Extruded rubber profiles are made through a process called extrusion, which involves forcing a rubber compound through a shaping die to create a continuous length of a specific cross - sectional shape. This manufacturing technique allows for the production of complex shapes with consistent dimensions, providing a high level of customization. There are various types of rubber materials used in the extrusion process, including natural rubber, neoprene, silicone, and fluorosilicone rubber. Each type of rubber has its unique properties that make it suitable for different applications.
When it comes to selecting a rubber profile for vacuum applications, the properties of the rubber material are of utmost importance. Vacuum conditions present a set of challenges that the rubber must withstand, such as low pressures, temperature variations, and potential exposure to chemicals or gases.
Challenges in Vacuum Applications
Vacuum environments can impose several stringent demands on rubber components. One of the most critical issues is outgassing. Outgassing occurs when volatile substances within the rubber material are released into the vacuum. These volatile substances can contaminate the vacuum chamber, deposit on sensitive equipment surfaces, and even affect the performance and integrity of the overall system.
Another challenge is the mechanical stress that the rubber profiles may experience under vacuum conditions. The difference in pressure between the inside of the rubber and the vacuum environment can cause the rubber to expand or contract, which may lead to deformation, cracking, or failure of the component over time. Additionally, in some high - vacuum applications, the rubber may be exposed to extreme temperatures, both high and low, which can further impact its physical and chemical properties.
Rubber Materials for Vacuum Applications
Fluorosilicone Rubber
Among the various rubber materials available, fluorosilicone rubber stands out as an excellent choice for vacuum applications. Fluorosilicone rubber offers a combination of properties that make it well - suited to handle the challenges of vacuum environments.
Fluorosilicone rubber has extremely low outgassing characteristics. It has a tight molecular structure that reduces the amount of volatile substances trapped within the material. As a result, when exposed to vacuum conditions, the amount of outgassing is minimal, which is crucial for applications where contamination can significantly impact the process or equipment.
Moreover, fluorosilicone rubber exhibits excellent resistance to temperature extremes. It can maintain its elasticity and flexibility over a wide range of temperatures, from - 55°C to 200°C. This makes it suitable for applications that involve both cold and hot vacuum processes.
Fluorosilicone rubber also has good chemical resistance, which is important in vacuum applications where the rubber may come into contact with various chemicals or gases. It can resist the effects of many solvents, fuels, and oils, ensuring the long - term durability of the rubber profile in harsh environments.

Other Rubbers
While fluorosilicone rubber is a top - performer, other rubber materials such as natural rubber or neoprene may have limited applications in vacuum environments. Natural rubber, for example, generally has a higher outgassing rate compared to fluorosilicone rubber, which makes it less suitable for high - vacuum applications. Neoprene also has its limitations, particularly in terms of temperature resistance and chemical compatibility.
Performance of Extruded Fluorosilicone Rubber Profiles in Vacuum
Extruded fluorosilicone rubber profiles have demonstrated outstanding performance in vacuum applications. Through advanced extrusion techniques, these profiles can be manufactured with precise dimensions and consistent properties, ensuring a reliable and leak - free seal in the vacuum chamber.
The low outgassing properties of fluorosilicone rubber prevent contamination of the vacuum system, which is essential for processes such as semiconductor manufacturing, aerospace applications, and particle accelerators. In semiconductor manufacturing, for instance, any contamination can result in defective chips or reduced yield, making the use of low - outgassing materials like extruded fluorosilicone rubber crucial.
In addition, the mechanical stability of extruded fluorosilicone rubber profiles under vacuum conditions is remarkable. The material's ability to maintain its shape and physical integrity despite the pressure differential provides a long - lasting solution for the vacuum system. The rubber's resistance to temperature variations also adds to the reliability of the profiles in applications where temperature cycling is common.
