2021/4/27 · ISO 1 is an international test standard for air filters that from 1 July 2018 has replaced EN 779. ISO 1 classifies air filters based on particulate matter (PM), which makes it possible to directly see connections to our health and air pollutants.
2021/3/31 · Today, the predominant polymers used are PTFE (polytetrafluoroethylene), polypropylene, PVDF (polyvinylidene difluoride), and acrylic copolymer. All of these polymers can be treated in order to obtain specific surface characteristics that can be both hydrophobic and oleophobic (repelling liquids with low surface tensions, such as multivitamin infusions, lipids, surfactants, oils, and organic solvents).
(USDA) has accepted Teflon® PTFE, FEP, and PFA fluoropolymer resins that comply with 21 CFR 177.1550 as components of materials in direct contact with meat or poultry food products prepared under Federal inspection. Resins that comply with 3-A Teflon®

ASTM F2101-01 is a standard using an aerosol of Staphylococcus aureus (S. aureus) to evaluate the BFE of face-mask materials. Other types on bacterial organisms may be used, however they may give different results because of differences in shape and size. S. aureus has an approximate diameter of 0.8 microns.
Standard Specification for Implantable Polytetrafluoroethylene (PTFE) Sheet, Tube, and Rod Shapes Fabricated from Granular Molding Powders F755 - 19 Standard Specification for Selection of Porous Polyethylene for Use in Surgical Implants
Teflon PTFE is FDA Food Grade compliant. PTFE resins have an upper service temperature of 500º F (260 C) and is one of the most widely used fluoroplastic material. PTFE mechanical properties are low compared to other advanced engineering plastics, but its properties remain useful over a temperature range of -400° F to 400° F forming its broad operating range suitable for many applications.
SAMP2LCRB. This 33 mm syringe filter with a Hydrophilic PTFE membrane, for non-sterile filtration on the Samplicity G2 system, has a 0.45 µm pore size used in preparation of aqueous & organic solutions prior to chromatography or other instrument analyses. Millipore. pricing.
PTFE, or polytetrafluoroethylene, is a coated woven fiberglass membrane that is extremely durable and tolerant of even the most extreme weather elements. The woven fiberglass gives PTFE coated glass fiber its mechanical strength and providing the membrane with maximum flexibility. A range of PTFE material types is available that include PTFE-coated
