An
Ideal Laminate for Filtration and
Venting Application |
At
DeWAL, we have focused our experience in precision polymer
films to create new laminates combining Poro-Tex with several
other substrates. When your filtration and venting applications
demand the fine pore size of ePTFE but assembly operations
require the strength of other materials, turn to us. DeWAL
Poro-Tex con be bonded to virtually any surface, such as
Uni-Pore (UHMW-PE) polypropylene, polyethylene, polyester,
Kevlar® and glass fabric, among others.
Uni-Pore
has a planar surface ideal for use as backing in a laminate.
It will not pierce the ePTFE membrane, as nonwoven spun
bound materials can. In addition, DeWAL has developed
the technology needed to manufacture laminates without
adhesives, thereby enhancing chemical resistance and eliminating
added extractables.
The
composite of Poro-Tex and Uni-Pore withstands the rigors
of handling and die cutting. With its Uni-Pore backer,
the laminate is pleatable, it ideal for high-performance
filtration applications.
