* The Most Solvent Resistonce
of Polyurethane Elastomer *
A.
Characteristic:
The properties of this special
polyurethane elastomers give our squeegee a number of major
advantage:
◎
Excellent resistance and minimum swell to a wide
range of pastes, inks and
solvents
◎
High
resistance to wear and tear better elasticity
resulting in prints of uniformly high
quality material.
◎
Low compression set and wide range flexible can be
speedy change by the printing screen's
embossed
and intaglio.
◎
The sharp processed and various of shapes can be
printing of uniformly high quality
material.
◎
The hardness of squeegee is covered from 55 to 95
Shore A for meeting many kind of
different
requirements.
◎
There are 4 types squeegee: super solvent
resistance, solvent resistance,
abrasion-resistance
and anti-static at your free choice.
◎
The squeegees
meet RoHS requirement.
B.
Grade:
1. UP
type : Super solvent resistance squeegee It made of
special
polyester polyol, MDI and an extender
with a
linear, symmetrical diol incorporating an
aromatic
ring under strict control by our
development
team for several years long in
testing the
different solvents and then success.
It can resist
for kinds of high- top ink solvent, its
excellent
properties are more better than many
European &
America’s PU squeegees and
Vulkollan’s.
Our hardness of Shore 75A, in
MEK and
Toluene for 24 hours, the weight
increased is
21% & 13% only, and the others
are 40% &
30%., The main usages are precision
PCB (print
Circuit Board) and FPD (Flat Panel
Display),
Ceramic condensers and the other
high top
quality solvent screen printing.
2. AP
type : Solvent resistance squeegee
The properties and solvent resistance is not so
better as the
UP type’s squeegee, but the
testing of
weight increased and change of
hardness is
nearly as UP type. It also can be
used in
general PCB, FPD and the other screen
printing.
3. BP
type : Abrasion resistance squeegee
The solvent resistance is not so good as the UP
and AP types.
Its’ solvent resistance not only
better than
general PU squeegee but also better
in the
abrasion and mechanical properties. It
can be used
in graphics multi-purpose and
textile
printing.
4. UP-AS
type : Anti-static squeegee
By the use of special formula, the electric
resistance will reduce from
1.2×10Ω13/cm2 to
1.0×10Ω9/cm2.,
this improved electrical
conductive AS squeegee will avoid to powder
and impure
particle. This AS squeegee is
special used
for glass and tint printing.
