Suction cups and other rubber products

• Handling
• Storing
• Life expectancy

 
The following guidelines specify suitable conditions for handling and storage of suction cups and other rubber products. By applying these guidelines, the durability and properties of the suction cups or rubber products will be optimized for a long lifetime. Other conditions may increase the risk of premature deterioration like excess hardening, softening, permanent deformation or other surface damage. For most parts the guidelines are based on ISO 2230.

Handling
For sensitive applications, avoid contact with dirt or grease. Wear gloves and clean the products before putting them into operation.

Cleaning
For cleaning, use a mild detergent and lukewarm water.

Blooming
"Bloom" refers to a whitish layer on the surface of the rubber products, which is entirely normal and acts as a protection. The function of the rubber is not affected, and it is therefore not considered a defect. However, if not acceptable wash with water and a mild detergent.

Deformation
Products shall be stored in a relaxed condition, free from superimposed tensions and compressive stresses etc.

Storing
Temperature: The products should preferable be stored between 15 °C to 25 °C [59 °F to 77 °F]. If suction cups are taken from low temperature storage the temperature should be raised to ambient temperature.
Humidity: The relative humidity should be below 65 % and condensation should not occur. Very moist or very dry conditions should be avoided
Light: Store preferably dark or avoid direct sunlight or artificial light having a high ultra-violet content
Ozone and radiation: Ozone is particularly harmful to rubber, therefore avoid storing rubber in the same room as equipment capable of generating ozone, such as mercury vapour lamps or high-voltage electrical equipment. In addition, the product must also be protected from ionizing radiation

Rotation of stock
Apply FIFO (First In First Out) so that remaining items in stock are those of most recent delivery.

Life expectancy
Rubber is naturally aging which means that the material degrades over time. To obtain the expected functionality of the products, long storage time should be avoided. It is recommended that the products are used within 24 months.
