3. Package, storage and transportation:
(2). Fluoroelastomer should bestored in clean, dry and cool warehouse. It can be transported as non-hazardous chemicals and should be far away from pollution sources, sunshine as well aswater during transportation.
(3). It is suggested that fluoroelastomer storing time limit should be one year after production. If exceeding one year, these products should be retested, they could be used continuously after being retested up to grade.
