| 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's Poro-Tex can 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, making it ideal for high-performance
filtration applications.
