Viscosity

  Most exiting characteristic of CMC is the range of viscosity that could be achieved when
it is dissolved in water. High viscosity CMC types are prepared from cotton linters and
medium viscosity types are made of wood pulp. If very low viscosity levels are
necessary, chemical oxidants will be used in preparation.
  CMC solutions are non-Newtonian. The rate of flow does not vary directly with applied
force. There are many viscosimeters used to measure viscosity of CMC solutions
e.g.;Brookfield, Hoppler, Engler. Technical specifications of UGUR CMC are declared by
using brookfield Viscosimeter. If data of various viscosimeters are to be compared, an
expert opinion should be asked.

Particle Size :

UGUR CMCis delivered in two major particle size; Granules, Powder. Operation conditions
differ among users of CMC and these different particle sizes will facilitate handling,
transportation, solution and other conditions.


Screen Analysis for UGUR CMC :

Granules:
P>710µ                 4.5 %            bigger than 25 mesh*
710µ>p>335µ           85.5 %          from 25 mesh through 45 mesh
355µ>p150µ            10 %            from 45 mesh through 100 mesh

Powder:
150µ>p>75µ               37 %          from 100mesh through 200mesh
75 µ>p                    63 %         through 200 mesh
( P: represents particle size,*: ASTM mesh)

Fine tuning of particle size is also possible. We can further process CMC in order to
decrease particle size and very fine powder can be obtained. Please contact us for
additional requirements.

Moisture :

CMC absorbs moisture from the air. Absorption rate will depend on the temprature and
humidity of surrounding air. UGUR CMC has max. 10 % (by weight) moisture when it is
packed. Once the package is opened it could absorb moisture. Therefore, while weighting
the proper amount of CMC one should take into consideration the moisture level of CMC
in torn pack.

pH:

pH of UGUR CMC is between 6.5 - 8.5 for 1 % solution.

Degree of Substitution(DS):

Cellulose is completely insoluble in water. To achieve a water soluble product, hydroxyl
groups are etherified and converted into carboxymethyl groups by reacting them with
sodium hydroxide and MCA. In etherification the degree of substitution(DS) varies from
0.4 to 3.0 the theoretical maximum, depending on the amount of sodium carboxymethyl

groups added.
Main commercial types has the DS of 0.55 through 1.35. Most of the CMC applications
require a DS value lower than 1.0.UGUR CMC offer DS of 0.65 through 1.35. For various
viscosity levels and purification grades we can offer normally etherified and highly
etherified CMC.
.
Active Content:


UGUR CMC is available in three major grades:

*Food Grade or Pharmaceutical Grade:                 Min. CMC Content % 99.5
*Purified Grade:                                     Min. CMC Content % 97
*Technical Grade:                                    Min. CMC Content % 65


  Although these grades are standard, any level of purification degree can be achieved
according to the needs of the customer.
