Cellulose ethers constitute a dust explosion hazard. Dust formation and deposits must be kept to a minimum to avoid ignitable dust/air mixtures. Ignition sources such as naked flames, hot surfaces, sparks, and static electricity should be avoided. CELOPRO starts to decompose at about 200°C, with an ignition temperature of >360°C. It burns easily, and the fire may spread.
Packed in 25 kg multilayer paper sacks with polyethylene intermediate layers and inner P.E. bags. 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. For high viscosity grades, a slow loss of viscosity may occur after lengthy storage (>1 year). CELOPRO absorbs moisture from the air. Once opened, the container must be resealed and kept tightly closed.
