Dextrins(yellow & White)

DEXTRINS


Dextrins are starch converted products which find applications in textiles,
adhesives, dyes, foundries and other industries.

Advantages:



Dextrin providesExcellent adhesive propertiesHigh strength films.Wide range of water solubilities.



Description:






Dextrins
are partially hydrolysed starches that are prepared by heating or
dry roasting in the presence of a catalyst. This dextrinization
reduces the larger starch molecules into smaller dextrin
components. The dextrinization process is controlled to result in
several different grades of white and yellow dextrins.





Common
to all these grades of
Dextrins, however is their
ready solubility in water, almost wholly or partially. The
controlled processing of Dextrins
gives them varying physical
properties such as decreased tendency of aqueous suspension to form
gel and low viscosity of solutions which can form a continuous and
uniformly thin film on drying. Dextrin films have greater elasticity
and strength than mere starch films with equal thickness.

Applications:Applications
of Dextrins
in various industries are outlined below:







Textile
Industry.





White Dextrins
are ideally suitable for textile industry due to their high adhesive
property and increased penetration. In textile printing, Dextrins
are used as thickners.









Adhesive
Industry





Because
of their greater adhesive strength and fluidity, Dextrins
are widely used in the machine labelling of tins, cartons, packages,
envelopes, etc. In book-binding, carton sealing, cigarette pasting,
match-head & match box making, and in the manufacture of spiral
and convolute tubes, Dextrins
are increasingly used.





Dyes
Industry


Dextrins
in dyestuff industry are
used as a diluent to standardise the dyes with respect to the ranges
of colours.





Foundry
Industry


Yellow
Dextrins serve
as an excellent binding agent for sand cores in foundry operations.
They give high green bond strength necessary for the mould to remain
intact during handling. Depending
on the properties required by the customers, a specific grade of
Dextrins can be offered.











Availabity:50 Kg bags. Other
packing requirements may be catered to on the request of
the customers.
