Since 2006, Focus on rubber seals

O-ring storage conditions and storage life

by:ORK      2022-11-20
O-ring storage conditions O ring manufactures are affected by various external environmental factors, such as: distortion, oxygen, ozone, light, heat, humidity, oil, or chemical solvents, etc. O ring manufactures may be affected by physical and chemical change in nature and fail. The storage, cleaning and maintenance of rubber seals seals are basically stipulated in DIN7716, ISO2230, DIN9088 and other standards. 1: 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. 2: Humidity: The relative humidity of the warehouse should be less than 70%, avoid too humid or too dry, and no condensation. 3: Lighting: Avoid sunlight and strong artificial light sources containing ultraviolet rays. UV-resistant bags provide optimum protection. Red or orange paint or film is recommended for warehouse windows. 4 Radiation: Avoid ionizing radiation damage to seals. 5. Oxygen and ozone: The rubber material 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. 6 Deformation: The rubber parts should be placed in a free state as much as possible to avoid tension, compression or other deformation. 7. Contact with liquid or semi-solid materials: Do not contact with solvents, oils, greases or other semi-solid materials. 8. Contact with metallic or non-metallic materials: Contact with magnetic materials, cast iron, copper and its alloys is not allowed, or materials containing materials that will damage rubber. Seals should not be packaged with PVC material. Seals of different materials cannot be mixed. 9 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 the seal The shelf life of the seal is determined by the material type and storage conditions of the rubber. Under the recommended storage conditions, the shelf life of each material seal is as follows: 1 Polyurethane, thermoplastic material 4 years 2 Nitrile rubber, hydrogenated nitrile rubber, neoprene 6 years 3 Ethylene propylene rubber 8 years 4 Fluorine rubber, silicone rubber , 10 years for fluorosilicone rubber, 5 years for perfluorinated rubber, 20 years for perfluoro rubber, 6 years for polytetrafluoroethylene. After the above period is exceeded indefinitely, the characteristics of the rubber parts should be checked before use, or it can be used for a period of time.
