Storage & Handling

+
Storage

Inside storage is recommended. Flaked, pelletized or pastillated forms of this product may remass under the following conditions:

  • If stored near sources of heat
  • Upon prolonged storage above 30 deg C (86 deg F)
  • With pressure (e.g., stacking pallets two or more high)

 

Remassing has no influence on the physical properties of the finished product. However, it is strongly recommended that strict control of stored inventory be observed at all times, taking care that the oldest material is used first.
