POREFLON™ is porous membrane made of PTFE. PTFE stands for P oly T etra F luoro E thylene, it is a kind of fluororesin. It features chemical resistance, heat resistance, water repellency, high retention of very small particles and high flow capability. Pore size ：0.03～10μm. Thickness：10～100μm. Porosity ：25～95%.
Sep 07, 2005 · Furthermore, PTFE resists bacterial growth and every known chemical agent or solvent at low and high temperatures (PTFE melting point = 327°C, useful temperature up to 260°C). [12] The sampling device used for extracting dissolved gases in natural water consists of a PTFE tube connected to a glass sample holder with two stopcocks ( Figure 1 ).
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.
PTFE Membrane innovation expert. PTFE membrane (Polytetrafluoroethylene) technology uses patented and proprietary processes to sinter then skive PTFE into rolled membrane materials that can then be converted into numerous other forms. Our controlled processes enable us to manufacture a unique porous PTFE membrane with unmatched properties.
Introduction to PTFE Membranes. Classic Filters first introduced PTFE membranes in 2002. They are most commonly used in sample systems to protect expensive and sensitive analytical equipment. Because they are hydrophobic water is repelled from the surface and pores of the membrane and cannot pass through.
The high titer reduction and water intrusion pressures allow the membrane to repel high surface tension liquids while venting gases. PTFE membranes are used in a variety of healthcare applications such as vents on IV filters and spike vents, protecting equipment and sensors from fluids and contamination. Material characteristics include broad
Weldable Membranes. Venting membranes made from porous PTFE can be excellently welded on plastic parts, thermally or using ultrasonic technology. Welding enables a highly durable connection between the membrane and the component, even under harshest conditions. The membranes ensure reliable venting and protect the housing against penetrating
SunGod is the worldwide first and only expanded PTFE membrane manufacturer licensed to use Chemours Teflon fluoroplastic logo. This waterproof, windproof, and heat-resistant PTFE micro porous membrane is ideal for firefighter clothing, sports and leisure clothing, and military equipment material.
PTFE membrane filters are naturally hydrophobic with excellent chemical resistance, making them the ideal choice for sterile venting of gases*, non-aqueous solvents, acids, and aggressive fluids. Thin, highly porous membrane filter. Behaves as an absolute retentive membrane. Inert to most agressive solvents, including strong acids and bases.
PTFE has a high molecular weight and is generally an unreactive substance due to the highly stable nature of the fluorine and carbon bonds in its structure. Furthermore, the high electronegativity of the fluorine atoms gives the plastic an extremely water repellent surface and outstanding non-stick properties (Fig. 4.21).
FORBLUE™ Membranes for Chemical Separation. AGC launched the FORBLUE™ family in 2017 as a new brand of membrane products for separating various chemicals. The family includes membranes for electrochemistry, chlor-alkali electrolysis, electro/diffusion dialysis and gas humidification.
