ABOUT US Parsian Zist Company has been started its activities since 2008 in the import and distribution of laboratory equipments and consumables in the field of genetic engineering, cell biology, molecular, cell culture, immunology, biochemistry, materials and

Polymeric gas-separation membranes were commercialized 30 years ago. The interest on these systems is increasing because of the simplicity of concept and low-energy consumption. In the refinery, gas separation is needed in many processes such as natural gas treatment, carbon dioxide capture, hydrogen purification, and hydrocarbons separations. In these processes, the membranes have proven to

2020/9/1 · The SBS membrane showed better salt rejection of 99.97%, higher surface hydrophobicity and superior mechanical strength of 132 and 525 K Pa, respectively than them observed with PTFE membrane (117 ,345 K Pa) due to the high thickness and large pore).

2021/6/28 · The membranes can be used in petrochemicals, aerospace, nuclear, carbon-free energy, and medicine. The latest results of research into the physical and chemical properties and biocompatibility of the membranes obtained are published in the Journal of Fluorochemistry (IF: 2,332; Q1).

Chemical resistance ECTFE. ECTFE, also known as Halar®, is often chosen for applications requiring excellent barrier resistant properties. Products out of ECTFE have excellent mechanical, electrical and chemical properties. Note: The chemical resistance of each polymer is mainly determined by the chemical structure of the material and the

Membrane Filters – Liquid Filtration; Absolute rated membrane filters provide precise, repeatable, sub-micron level filtration. Absolute rated, PTFE membrane pleated filter cartridges High surface area, integrity tested polyethersulfone membrane filter cartridges for

PTFE compound coated EPDM membranes are available from multiple sources. premium EPDM. product must be a premium EPDM as PTFE coating on poor quality EPDM is not effective. Cost to employ PTFE coated rubber is a premium of about 100%. Typical 9” disc membrane. cost of $3 - $5 while PTFE coated would be $6 - $10 each.

2020/5/1 · We have developed novel Teflon AF2400/polyethylene (PE) membranes for organic solvent nanofiltration. It has high pure solvent permeances of 3–8 L/m 2 -h-bar for ethyl acetate, toluene and hexane. Fabrication of the membranes is greatly simplified because it does not require cross-linking or pore preserving agents.

2009/11/1 · Abstract. Pervaporation is the most promising technology in the molecular-scale liquid/liquid separations existing in biorefinery, petrochemical, pharmaceutical industries, etc. for being highly selective, economical, safe and ecofriendly. However, the inadequacy of the existing polymeric membranes hinders the full exploitation of the

PTFE Unlaminated Membrane Filters, Hydrophobic, 3 Micron, 47mm, 100/Pk Product code T300A047A Q. What is the difference between nominal and absolute pore size ratings? Nominal pore size ratings are provided as a general indication of filter retention.

TECHLINK built and installed a new membrane filtration system for the purification of brine at a large chlor-alkali facility in Thailand. The system uses a state-of-the-art porous PTFE membrane technology licensed by Profilco B.V of The Netherlands. It will allow the recovery of waste brine produced by the traditional brine purification system.

2021/6/29 · PTFE is known to be the most stable existent polymer. According to the scientists, it is a simple, affordable and easily scalable method, which will allow obtaining chemically stable membranes in industrial-scale production. The membranes can be used in petrochemical, aerospace, nuclear industries, carbon-free energy and medicine.

MS®PTFE membrane is made from e-PTFE by using the unique technology. And there are more than 1400 million holes per square centimeters,so it has high porosity. The membrane can be laminated with a great variety of fabric and paper,and used for filtration
