Viscose

Other Names: Sometimes referred to as rayon viscose by converting cellulose to the soluble xanthate, which can be spun into fibers and then reconverted to cellulose by treatment with acid. Wood pulp is steeped in caustic soda and then shredded and aged. It is then treated with carbon disulfide of cellulose xanthate. After filtration and deareation, the remaining solution is known as viscose.

Viscosity: Ranges from 5,500 cPs. to 55,000 cPs. with the most normal range being 5,500 cPs. to 11,000 cPs.

Remarks: Much of the viscose ends up as cellophane or rayon fibers.

Pump Notes: Cast iron construction is satisfactory. Pumps are normally supplied with shaft packing.
