Rubber products are affected by various external environmental factors. Such as: distortion, oxygen, ozone, light, heat, moisture, oil, or the influence of chemical solvents, etc., may fail due to changes in physical and chemical properties. In ISO2230, DIN9088 and other standards, basic regulations are made on the storage, cleaning and maintenance of rubber seals.

Temperature: 5-25℃ is the ideal storage temperature. Avoid exposure to heat and sunlight. Seals taken out from low temperature storage should be placed in an environment of 20°C before use.

Humidity: The relative humidity of the warehouse should not be less than 70%, avoid too wet or too dry, and no condensation.

Lighting: Avoid sunlight and strong artificial light sources containing ultraviolet light. UV-resistant bags provide optimum protection. Red or orange paint or film is recommended for warehouse windows.

Keep in original carton or airtight container to prevent oxidation.

Radiation: Avoid ionizing radiation damage to seals.

Oxygen and Ozone: Rubber materials should avoid exposure to circulating air. This can be accomplished by packaging, wrapping, storing in an air-tight container, or other suitable methods. Ozone is harmful to most elastomers. Avoid the following equipment in the warehouse: mercury vapor lamps, high-voltage electrical equipment, motors and other equipment.

Deformation: Rubber parts should be placed as freely as possible to avoid tension, compression or other deformation.

Contact with liquid or semi-solid materials: Do not come into contact with solvents, oils, greases or other semi-solid materials.

Contact with metallic or non-metallic materials: Contact with magnetic materials, cast iron, copper and its alloys, or materials that contain rubber damage is not allowed. Seals should not be packaged with PVC material. Seals of different materials cannot be mixed.

Cleaning: As needed, the seals can be cleaned with soap and water. However, water should not come into contact with fiber reinforced seals, rubber-to-metal bonded seals, and AU material seals. Disinfectants, organic solvents and tools with sharp edges should not be used. Cleaned seals should be air-dried at room temperature away from heat sources.

The shelf life of seals is determined by the material type and storage conditions of the rubber. Under the recommended storage conditions. The shelf life of each material seal recommended by Domit is as follows:

Polyurethane, thermoplastic material 4 years

Nitrile rubber, hydrogenated nitrile rubber 6 years

Ethylene propylene rubber 10 years

Fluorine rubber, silicone rubber, fluorosilicone rubber 15 years

Perfluoroelastomer 20 years

PTFE Unlimited

After the above period is exceeded, the characteristics of the rubber parts should be checked before use. If the characteristics are good, it can be used for a period of time.

The company's seals should be used within the specified application parameters!
