Temperature impacts the life of a rubber seal. The temperature range in which it operates is critical to its life expectancy, and how well it performs. It is important that the rubber seal used in an application with extreme temperatures must be designed for that temperature range. Rubber is made up of several chemical bonds that keep the material flexible. Each bond has a different length, which means the rubber will change shape when you apply force to it. Heat and pressure cause those chemical bonds to break, which results in lost elasticity. Overall, rubber seals that are exposed to thermal stress will lose their flexibility and elasticity over time.
Rubber, like most other materials, has a temperature range in which it works the best. These temperatures vary by the type of rubber material used in the seal. Some have working ranges as low as -40 degrees and others can go as high as 150 degrees. When the temperature range is exceeded, the rubber will become brittle and lose its flexibility. The seal will no longer be able to fulfill its intended purpose, and thus demand replacement.
Choosing the Right Material is Crucial
There are different types of rubber seals and they each have their own unique characteristics. For example, there are natural rubber seals, silicone rubber seals, and nitrile rubber seals. Silicone rubber seals are the most durable and heat resistant of the three. They have a high resistance to heat and will not crack or break down over time. The selection of the right material and seal design is critical in order to ensure that they can resist temperature variations and last over a long period of time. The following are a few amongst the most popularly used rubber materials for making seals that get exposed to varying temperature ranges.
With that being said, it is very important for industrial rubber seal manufacturers to understand how temperature differences affect the performance of rubber seals. It is also crucial for them to know how temperature changes will affect the life of their seals. Hence, in order to get the rightly manufactured rubber seals for your applications, it is highly recommended to get them done from expert seal manufacturer like SSP Seals. With several years of experience in the field, the team at SSP Seals is aware of the properties and behaviors of rubber materials they are working on. With such an expert in hand, you would be able to get the best performing rubber seals for high-temperature applications.
