Chemical formula [C6H7О2(OH)2ОCH2COONa]n

main prorerties and fiels of usage

Commercial grade sodium-carboxymethylcellulose (Na CMC) is the mixture of fibrous-grainy or powder-like material from the white to the cream color.

Na CMC is applied in oil-refining industry, natural gas industry and geology, in the production of synthetic detergents, in the mining and chemical industry, in the paper making industry, in the building industry, as different adhesive compositions.

Commercial grade Na CMC does not have a toxic and irritating effect, does not educe any toxic substances to the environment and does not influence at a human body during direct contact.

Notes:

  1. Index «fineness of grinding» is rated only for powder-like product and defined on consumer’s request.
  2. NaCMC production with fraction of total water mass not more than 40% for pulp and paper enterprises is allowed according to agreement with consumer.

package

Product is packed into the polyethylene or polypropylene laminated bags.

Na CMC with the moisture content of more than 20 % is packed into the polyethylene bags. The mass of product in the bags must be 15-30 kg with the permissible deviation of ± 1%.

It is transported by all modes of covered transportation means. During the transportation-unloading the product must be protected from the action of atmospheric precipitations.

 GUARANTEE STORAGE LIFE

1 year from the date of manufacturing.
