Storage of Sheet Rubber Products

Rubber products in storage can be adversely affected by the following items:

The warehousing area should be relatively cool, dark and free from dampness and mildew. All items should be stored on a first-in, first-out basis, since even under these conditions, an unusual length of shelf life could deteriorate certain products.

The ideal storage temperature for rubber products of 50 to 70 degrees F with a maximum limit of 100 degrees F. If stored below 32 degrees F, some products may become stiff and should be warmed before being placed into service.

Rubber products should not be stored near sources of heat, such as radiators and base heaters. Rubber products should not be stored under conditions of high or low humidity.

To protect against the adverse affects of ozone, rubber products should not be stored near electrical equipment that may generate ozone and should not be stored for any lengthy period in geographical areas of known high ozone.

Conditions of direct and reflected sunlight should also be avoided. Whenever feasible, rubber products should be stored in their original shipping containers, especially when such containers are wooden crates or cardboard cartons, since this will provide protection against the deteriorating effects of oils, solvents, and corrosive liquids; and will also afford some protection against sunlight.

Certain rodents and insects thrive on rubber products, so adequate protection should be provided from them.
