¿Cómo afectan las temperaturas extremas en las juntas de caucho?

The sealing elements in a circuit or in machinery are very important elements to ensure the correct operation of the elements that make up a circuit that needs to be watertight. Moreover, in many installations, they become even more important, as they are essential elements for the safety of workers and operators who may be in the vicinity.

It is crucial to choose the correct type of gasket for each installation, as the properties of different types of gaskets can vary greatly and choosing the wrong type of gasket will result in a malfunction of the gasket, with the associated dangers and likelihood of accidents.

This is especially relevant in relation to installations where the rubber gasket will be subjected to extreme temperatures, as such situations can have a major impact on the behaviour of the gasket, as well as affecting its durability and strength.

Extreme temperatures and rubber gaskets

Any installation that is subjected to extreme temperatures requires specific rubber gaskets, given that its environment will have very adverse conditions and, therefore, they must be prepared to withstand them.

One of the most damaging factors for rubber gaskets under extreme temperatures is the expansion factor. Materials subjected to high temperatures tend to expand and expand, so a gasket that is not suitable to withstand high temperatures will be deformed and lose its sealing properties, putting the installation at risk.

The other key factor is the degradation of the materials that make up the rubber gasket. If the installed gasket is not made of materials resistant to extreme temperatures, it will eventually degrade to a point where its sealing properties drop or it reaches the point of rupture, which can be very dangerous.
