Packaging, Storage and Safety instructions

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, sparkand 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.


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.
