POLYESTER
SQUEEGEE
Often times there are advantages to using a Polyester Squeegee Blade over the
more conventional Stainless Steel Squeegee. Most notably, the Polyester Squeegee
will not pit, rust, corrode, or delaminate. The Polyester blade will reduce
the wear on rolls and screens by virtue of the fact that the squeegee is softer
and more flexible than stainless. This allows the polyester blade to be run
with less pressure minimizing the friction and thus, the wear that occurs. Polyester
Squeegee is also compatible with the majority of solvents, coatings, lacquers,
varnishes, water, and alcohol based inks commonly used in flexographic, gravure,
and Rotary Screen Printing. (Please see the accompanying list.)
The general blade sizes used in Rotary Screen Printing are as follows: 40mm
x 0.61mm, 40mm x 0.39mm, 4mm x 0.50mm, 55mm x 0.61mm, and 55mm x 1.00mm. (Other
sizes and samples are available upon request.)
These sizes have evolved as the most popular as squeegee blades typically are
used in a "trailing" technique at approximately a 65° angle to the
roll or screen.
This technique involves a scraping action that forms a wedge of ink in the angle
between the squeegee and the screen or roller surface. It is at this angle
that solid particles can become trapped, causing damage to both the screen and
squeegee. For this reason, a high standard of ink filtration and cleanliness
is
essential when using either the Polyester or Stainless Squeegee.
