POLY(VINYL ALCOHOL)-β-CYANOETHYL
ETHER
The
poly(vinyl alcohol)-β-cyanoethyl ether is a
high polymer compound,non poisonous,and
slightly yellow glass state solid.It is
strong adhesion,unsolvable in water,easily
soluble in the organic solvent of acetone
and methylene dichloride etc.It has better
electric properties,higher dielectric
constant normally up to 15-16,is a excellent
dielectric material.
This product mainly is used in the
dielectric materials of making the
electroluminescent image display screen,can
enhance shining lightness,increase
adhesion,enbance using reliability,and as a
adhesive of ceramics and glass article.
