Product Details
 

Feature and applications:

Sodium lignosulfonate as dye dispersant Grade-1 is made from raw material sulfite pulping of  selecting high quality wood through introduction of sophisticated production equipment, advanced production technology, by experienced technical personnel and skilled workers carefully prepared.  Sodium lignosulfonate is a natural polymer poly composition, also is an environmentally friendly "green" dye dispersant.

 

Sodium lignin dye dispersant Grade-1 is a soluble brown powder, high molecular weight, high sulfonation, a phenolic hydroxyl group content. Insoluble substance content is very low, low calcium and magnesium content and low mineral content.  

Sodium lignin dye dispersant Grade-1 is mainly used for disperse dyes, processing of vat dyes, with good grinding effect, the lower Azo dye reduction, high heat stability and good high-temperature dispersibility .

 

Environmental conditions:

Sodium lignin dye dispersant Grade-1 with features of non-toxic, harmless, readily biodegradable.

 

Packing:

1.     packing by 25kgs/composite waterproof paper bag,

2.     packing by 25kgs/ plastic woven bag lined with plastic flim

3.     packing in tonnage bag

 

Storage life:

Sodium lignin dye dispersant Grade-1 can be stored for more than two years under the condition of ventilation drying.
