OUR MEMBRANE TECHNOLOGIES

MICROPOROUS

Our microporous technology is based on a unique structure comprised of a highly regular pore structure with interconnects in the sub micron range. The membrane is hydrophobic (water hating) and repels water droplets, even under high pressure. At the same time the membrane breathes by allowing the passage of water vapour molecules through interconnecting pores < 0.02 µm in diameter.

HYDROPHILIC

Our hydrophilic (water-loving) membrane has a solid structure. It is manufactured by a novel process that ensures we can produce a membrane with a very uniform structure which is key to the consistency of its properties in performance. The solid structure stops penetration of water droplets but then breathes by absorbing water molecules in the vapour phase. The mechanism for breathability is assisted by chemical groups built within the polymer chemistry that have a high affinity for water molecules.

PTFE BICOMPONENT

Our PTFE bicomponent membrane is a hybrid structure combing a hydrophobic microporous PTFE layer coated with a solid, breathable hydrophilic PU layer. The two layers work in synergy to define the overall performance. The PTFE layer is the backbone on which the basic properties are built, while the hydrophilic layer modifies the final performance properties of the membrane. We modify the chemistry of the PU coating layer to achieve a range of properties tailored to the end use.
