PTFE Micropore Surface Coating. The PTFE has a micropore surface coating on PTFE-basis showing marked advantages for the separation of agglomerating, strongly adhesive, or tacky dusts. The advantages of the PTFE coating are due to two essential effects: The filter-active coating begins to separate the dust on the surface area.

Hydrophobic PTFE • PTFE membrane supported on a non-fiber releasing. polypropylene backing • Enhanced chemical resistance • Selected types may be in-line steam sterilized (126°C, 30 min) or autoclaved (121°C, 30 min) APPLICATIONS • Filtration of photo resists and organic solvents • Uses in the electronics industry and in chemical
The hydrophobic PTFE membrane is ideally suited for filtering acids, bases and solvents. In addition, the hydrophobic membrane provides superior flow and pressure drop characteristics per unit area for gas filtration and tank venting applications, fermentation feed air.
Micro-porous membranes are generally made from the polymers 27 PTFE, polyurethane (PU), polyolefins, polyamides, polyester, polyether and polyether based copolymers, with the first two mentioned (i.e. PTFE and PU) being the most popular. In most cases they can be cast directly onto the fabric (i.e. coated) or formed into a membrane and then laminated to the fabric.

Aug 07, 2018 · Polytetrafluoroethylene (PTFE) Membrane. Hydrophobic, highly inert, and durable, PTFE is a popular material with a wide operating temperature range and resistance to the damaging effect of many chemicals. When should you use it? DO USE: for filtering solvents and other aggressive chemicals, such as acetone and DMSO.
All Micropore membranes are Triton-free. except Nylon • Thin membranes with high porosity: Uniformly thin. membranes (typically 150 μm) with high porosity (about. 80%) provide high gas and liquid flow per unit area. High. porosity also provides high surface area for adsorption or. binding • Thermostable: All Micropore membranes can be sterilized
Cationic surfactant (CS+) in urban river water and sediment was extracted and determined spectrophotometrically with 2 membrane filters. The CS+ in the water samples, mostly in the form of an ion associate with the coexisting anionic surfactant (AS), was collected on a polytetrafluoroethylene (PTFE) membrane filter and eluted with methanol.
Hydrophilic PTFE membranes are typically used in filtering aqueous solutions, while hydrophobic PTFE membranes are typically used for filtering organic solvents and gases as well as particle monitoring. Polyvinylidene chloride (PVC) filters are preferentially used with gravimetric analysis to quantify silica, carbon black, or quartz air particulates. Millipore® PVC membrane filters are produced from high-quality PVC and have been developed for use with ASTM, NIOSH, and OSHA air monitoring
