Porous PTFE membranes are chemically not affected and therefore suitable in aggressive environments. Partly due to the hydrophobic property, suitable for the laboratory analysis of samples. Most suitable for the measurement of chemicals and solvents. Pore size and porosity volume can be obtained as desired.
PTFE diaphragms, also referred to as membranes, are air-tight seals between two spaces with product and pressure, which typically differ from each other. Commonly used in pumps for the chemical and petrochemical industry, food and beverage industry and the pharmaceutical industry. This type of diaphragm or membrane is manufactured according customer specification. Applications include flow meters, pressure regulators, valves.
There are two common models. PTFE diaphragms for pumps (usually round) and PTFE diaphragms for valves (usually square and combined with an elastomer).
