MICROPOROUS PU

 

A hydrophobic (water hating) membrane with a unique structure, comprising of highly regular pores with interconnects in the sub-micron range. Allowing the membrane to repel water droplets, even under high pressure. While maintaining its breathable abilities by allowing the passage of water vapour molecules through interconnecting pores < 0.02 µm in diameter.

HYDROPHILIC PU

 

Our hydrophilic (water-loving) membrane has a solid structure. Manufactured by a novel process that ensures 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.

BICOMPONENT PTFE

 

A hybrid structure of 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 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.
