Unipore® and Porotex Products
RELY ON THE UNIFORMITY AND STRENGTH OF UNI-PORE ™ POROUS UHMW-PE
Through a proprietary process, DeWAL produces thin porous films
of ultrahigh-molecular-weight polyethylene (UHMW-PE). These Uni-Pore
films uniform pore sizes in
 all
three axes. The pore size distribution is very uniform, with
nomial values from 50.0 microns to 2.5 microns. The torturous
path through the film creates an efficient filter medium, and
the high chemical resistance of UHMW-PE allows filtration of
most liquids and gases.
Uni-Pore provides excellent chemical and abrasion resistance
with superior mechanical strength. The material is easily
pleatable and die-cuts cleanly, making it ideal for filter and
diagnostic applications. Uni-Pore is recommended for use at
temperatures below 250°F for diagnostics, filtration, flow
control and frit applications.
A naturally hydrophobic and oleophobic material, Uni-Pore
aggressively absorbs oil, even from oil-water dispersions.
Through a proprietary process, DeWAL can render the material
hydrophilic or oleophobic.
