Rubber Rings Manufacturers Introduce The Storage Method Of High-pressure Seals

Update:15 Aug 2022

High-pressure seals and supports are often stored as spare parts for extended periods of time. The physical properties of most rubber materials will change during storage and eventually can no longer be used, such as too hard, too soft, cracks and cracks, or other forms of surface aging. These changes are the result of a particular factor or a combination of factors, such as deformation, oxygen, ozone, light, heat, humidity, or oils and solvents. The shelf life of these products can be greatly extended if some simple measures are taken. Points for storage, cleaning, and maintenance of elastomeric sealing elements are set out in international standards. Shelf life recommendations for different material grades of elastomers in the standard. Rubber Rings Manufacturers Introduce In order to maintain optimum physical and chemical properties of parts, the following rules should be followed:

1. Heat, the ideal storage temperature is +5°C to +25°C, and direct contact with heat sources, such as boilers, radiators, and direct sunlight should be avoided. If the temperature is below +5°C, the seal may be stiff and should be handled with care, allowing the temperature of the seal to return to around 25°C before use.

2. Humidity, the relative humidity of the storage room should be less than 70%. Too wet or too dry should be avoided.

3. Light, like rubber seals should be stored away from light, especially not in sunlight or artificial lights containing ultraviolet components. Parts should be individually packaged in UV-resistant packaging. It is recommended to cover the storage room windows with red or orange curtains.

4. Radiation, in the case of electronic radiation, special protection should be taken to prevent parts from being damaged.

5. Oxygen and ozone, if possible, elastomers should be packaged and stored in airtight containers free from air. Since ozone can damage elastomers, equipment that may generate ozone such as UV lamps, high voltage equipment, electric motors, spark sources or static discharges should not be placed on the premises where elastomers are stored. Combustion gases and organic vapors are also generated by photochemical action Ozone, so these gases cannot be present in the storage room either.
