HANDLING & STORAGE
Sheltered and temperature controlled storage conditions (temperature <25°C). No stacking of pallets. Remove the plastic film protection after transport once in good storage conditions.
6 months in flaked form and 12 months in block form. As this product is sensible to gradual oxidation and to compaction, appropriate storage and a strict inventory control is to be followed (oldest material used first), especially during hot periods. Be aware that temperature, time and pressure is of influence on the re-massing phenomena.
Block form in cardboard drums of 200 kg on pallets of 800 kg. Pastillated form in 25 kg paper bags on wrapped pallets of 1000 kg net weight.
