Breathable and Waterproof Membrane

Porelle® sport is a range of hydrophilic membranes that are lightweight, quiet, flexible and durable, and available in different thickness options of 12 - 40 µm.

Porelle® sport differs from TPU films. It is not an extruded or blown film, but produced using a novel coating process designed and developed in-house. It remains consistently waterproof in use due to its unique uniform structure. It is a soft tactile membrane that lacks the crinkle effect often associated with other films.

Porelle-Hydrophilic

It has been proven to be extremely easy to handle in adhesive or flame bonding lamination processes ensuring high productivity yields.

 

Performance Benefits

Porelle® sport is designed for use in active apparel. Each membrane offers a number of performance benefits, but are also tailored to meet enhanced requirements for specific apparel applications:

  • 12 or 18 μm: lightweight and highly breathable for use in garments

  • 25 μm: low noise and extremely waterproof for use in gloves

  • 25 µm: durable and extremely waterproof for use in footwear

  • 25 µm: low noise and very soft for use in hats

 

Waterproof

When laminated to a fabric porelle® sport can achieve waterproofness levels in water column tests in excess of 10,000 mm. It will retain this performance after multiple wash cycles.

Porelle® sport has a solid structure that physically stops water-droplets and wind passing through the garment. Rain, snow, or wind. The membranes waterproofness does not however, impede its ability to control the microclimate within the garment and allows water which accumulates as sweat, to escape the garment leaving the user dry whilst retaining temperature control.

Breathable

When we work hard, we sweat. This creates a micro-climate inside the garment. If the sweat becomes trapped inside the garment it can quickly form a wet layer leaving you feeling clammy and hot when you’re working hard, then becoming cold as you cool-down.

Porelle® sport controls the micro-climate inside the garment by absorbing and dissipating sweat through the diffusion of water vapour molecules. When you work hard porelle® sport breathes, keeping you comfortable.
