CYANOETHYL CUCROSE
Cyanoethyl
sucrose is a high polymer compound ,nonpoisonous.It
is a glass state viscous liquid,tastes
bitter,strong adhesion,unsolvable in
water,easily soluble in the organic solvent
of acctone and methylene dichloride etc.It
has excellent electric properties,especially
is special high dielectric constant up to
35-38 ,none of the general high polymers
have which higher than it ,is an outstanding
dielectric material.
This product is used in the dielectric
material of making the electroluminescent
image display screen, can enhance shining
lightness,may extent service life,also is
used as an impregnant of the large capacity
energy storage capacitor,to enhance its
capacitance,in order to reduce volume of
parts and to lighten weight of the
product,still is used in the high polymer
material as inner plasticity agent,to
enhance toughness,as well dielectric
material of other electronic component.
Chenical Formula(C12H14O3COCH2CH2CN)nNote
The product is a non-easy flammable,non-easy
explosive goods.When it is stored , care
should be taken to avoid strictly the
sunlight and seal tightly,and to avoid
absorption of moisture and water.
Original package goods has shelf life for 5
years.
