Storage guidelines for elastomers

The life of elastic materials is not unlimited. Sometimes we feel the need to keep elastomeric components for a long time to ensure its availability in case of an urgent technical service. 

We highly recommended to follow these storage guidelines for products made of elastomeric materials to make sure that they maintain their initial properties.

These storage guidelines are not exclusive to O-rings, they can also be used for any other product such as hydraulic seals, pneumatic seals or flat gaskets, among others. In the case of products manufactured with additional components, such as metals, it is advisable to check whether the metal is free of rust or any other observable defect.

Storage times for elastic materials

Considerations for the storage of elastic materials

The storage period of elastic materials can be extended after the time indicated in the table above if the product is subjected to a proper inspection. Similarly, the life of an elastomer may be affected before the stated storage times expire if stored incorrectly. In this sense, we refer to the recommendations of DIN 7716.

All these values should be taken with the utmost caution. Elastic materials derived from rubber (elastomers) need to have their optimum quality properties. This is especially relevant if they are to be used under harsh conditions, such as with aggressive chemicals, in demanding applications, in high or low temperature environments or under high pressures or vacuum systems.

Some general lines to follow to achieve the maximum shelf life:

1. The storage space should be dry, cool, as dust-free as possible.
2. Temperature should not exceed -10°C to +15°C. In any case, the upper limit may be exceeded up to +25 °C. 
3. The articles must be protected from the source of heat and condensation. the ideal relative humidity is less than 65%. 
4. Store your rubber components in hermetically sealed packaging to protect them from UV and ozone. 
5. Do not store rubber close to flammable and corrosive products such as fuels, lubricants, acids, disinfectants, solvents or other harmful chemicals.
