Packaging, Storage and Safety instructions

Packed in 25 kg multilayer paper sack with polyethylene intermediate layer and inner P.E. bag.

When stored in closed containers, or in its original packaging in a dry place at room temperature, CELOPRO can be kept for a long time. In the case of high viscosity grades, a slow loss of viscosity can be measured after lengthy storage (>1 year). CELOPRO absorbs water from moist air. Once opened, container must be resealed and kept tightly closed.

Cellulose ethers constitute a dust explosion hazard. Dust formation and deposits must be kept to a minimum so that no ignitable dust/air mixtures can form. Ignition sources such as naked flames, hot surfaces, spark and static electricity should be avoided. CELOPRO starts to decompose at about 200° C. Its ignition temperature is >360° C. It burns easily and the fire may spread.
