Gore-Tex Gore-Tex is a waterproof, breathable fabric membrane and registered trademark of W. L. Gore and Associates. Invented in 1969, Gore-Tex is able to repel liquid water while allowing water vapor to pass through, and is designed to be a lightweight, waterproof fabric for all-weather use. It is composed of stretched polytetrafluoroethylene (PTFE), which is more commonly known as the generic trademark Teflon.

- Gore-Tex is a water-proofing material, a chemically inert form of expanded polytetrafluoroethylene (PTFE, or Teflon). Gore-tex is one of the most versatile waterproofing lamin…ates used for clothing and shoes. When the outside gets wet, the inside will stay dry due to the breathable Gore-Tex lining.

Enclosure materials High impact-resistant polystyrene (PS) enclosures are available to order. Polycarbonate is an amorphous thermal plastic material whose high heat resistance and excellent physical properties make it an ideal material for enclosures. Polycarbonate can withstand a wide range of temperature fluctuations and its good electrical properties are unaffected by humidity.

- Current Gore-Tex fabrics are constructed in this manner (Gore-Tex XCR® uses an extremely thin PU membrane). 3. PU-only membrane (hydrophilic monolithic) Waterproof-breathable fabrics can also be made without the PTFE layer because the PU membrane is essentially responsible for the bulk of moisture transmission.

The GORE-TEXÂ® MembraneThe heart of all GORE-TEXÂ® products The heart of all GORE-TEX® products. The pores are 700 times larger than a water vapor molecule which means perspiration passes right through. This is what makes the. membrane breathable. The microscopic pores of the membrane are 20,000 times smaller than a water droplet, which means that no rain can penetrate it. This is what makes the GORE-TEX® membrane waterproof. The membrane's structure is similar to that of a hedge. The wind is caught up entirely in the branching and thus averted from the body. This is what makes the GORE-TEX® membrane windproof.

- That said, most people still refer to the entire wp/br category as “Gore-Tex”, however, not all waterproof / breathable fabrics & rain wear is Gore-Tex – just like not all cars are Hondas and not all coffee is Starbucks.

How Does Rainwear Work? Laminates (which include Gore-Tex and eVent) are formed when a WP/BR membrane is bonded to the underside of a garment's face fabric, as if wallpaper was applied to a wall—in other words, membrane (wallpaper) + fabric (wall) = a laminate.
