Clear multi-sized flakes of polycellulose, with an average size of 9.5mm (3/8″). Cellophane is used in oilfield applications and cementing applications as lost circulation material. In non-oilfield applications Cellophane is used as a sealing agent supplement to other lost circulation material.
Cellophane works with low and normal density slurries and has excellent bridging properties. It is non-toxic, biodegradable, chemically inert and environmentally safe. Cellophane does not affect the compressive strength of the material.
