Chemically Resistant �?Supplies great chemical resistance in a number of applications that require tough process conditions
H2o entry force (WEP): the level of h2o tension required to have h2o split with the membrane. This is a critical evaluate when creating a drinking water-resistant venting or filtering membrane.
What ever your industry, our professional regional complex experts are keen to be aware of your special item requirements. Allow us to enable you to discover The best filter media Answer for your application.
Generally, absolute pore size scores, Particularly those depending on microbial retention, are similar from producer to manufacturer. There is certainly much more uncertainty for absolute pore sizing scores dependant on particle retention scientific tests, specifically for pore measurement ratings The Advantec unlaminated PTFE hydrophilic membrane filters are not completely hydrophilic. When wetted, they are going to turn out to be hydrophobic if allowed to dry. Also, they are going to grow to be hydrophobic if autoclave sterilized or in any other case subjected to temperatures >a hundred°C.
Porex Virtek PTFE water-resistant membrane is The most chemically resistant components accessible out there.
Ein großes Trouble dieser langkettigen poly- und perfluorierten Chemikalien ist, dass diese chemisch und thermisch sehr stabil sind und sich nur unter extrem hohem Energieaufwand wieder lösen lassen. Folglich werden diese durch die Umwelt nicht abgebaut.
When incorporating a PTFE membrane into your products, it’s critical to grasp the Bodily Homes impacting the components and performance from the part including:
Innovation
PTFE Membranes are extremely hydrophobic and show top-quality chemical compatability with agressive methods.

Hydrophilic membrane filters are usually applied with h2o and aqueous options. They will also be applied with suitable non-aqueous fluids.
Hydrophobic membrane filters are occasionally utilized with drinking water or aqueous answers; and, in these purposes, they need to initially be prewet by using a low floor rigidity, here drinking water miscible fluid prior to use.
Mentioned membranes also are made use of as vents to permit air to pass through when holding out drinking water and also other liquids. This is particularly beneficial in electronic devices, in which stress changes can destruction inner factors.
Once every one of the air during the pores is displaced, there are no more time any floor pressure forces and drinking water can certainly enter the pores, displace the minimal floor rigidity fluid, and go through the membrane. The membrane will then permit bulk movement of drinking water for so long as the pore stay water stuffed. If your membrane is permitted to dry (i.e. air enters the pores), then it needs to be pre-soaked with a low surface stress fluid once more before use with water.
