2. Aerogel - Wikipedia

   en.wikipedia.org/wiki/Aerogel

   The best radiation wavelengths to use are X-rays and neutrons. Aerogel is also an open porous network: the difference between an open porous network and a closed porous network is that in the open network, gases can enter and leave the substance without any limitation, while a closed porous network traps the gases within the material forcing ...

3. Waterproofing - Wikipedia

   en.wikipedia.org/wiki/Waterproofing

   In construction, a building or structure is waterproofed with the use of membranes and coatings to protect contents and structural integrity. The waterproofing of the building envelope in construction specifications is listed under 07 - Thermal and Moisture Protection within MasterFormat 2004, by the Construction Specifications Institute, and includes roofing and waterproofing materials.

4. Hydrogel dressing - Wikipedia

   en.wikipedia.org/wiki/Hydrogel_dressing

   Hydrogel dressing is a medical dressing based on hydrogels, three-dimensional hydrophilic structure. [1] The insoluble hydrophilic structures absorb polar wound exudates and allow oxygen diffusion at the wound bed to accelerate healing. [2]

5. Sympatex - Wikipedia

   Sympatex is a type of fabric that is branded as waterproof but "breathable", made or licensed by Sympatex Technologies GmbH a company founded in 1986. [ 2 ] [ 1 ] The fabric features a waterproof, windproof and breatheable membrane that is laminated to fabrics either on its inner surface or sandwiched between two fabric layers (often marketed ...

6. Adhesive bandage - Wikipedia

   en.wikipedia.org/wiki/Adhesive_bandage

   The adhesive sheet is usually a woven fabric, plastic (PVC, polyethylene or polyurethane), or latex strip. It may or may not be waterproof; if it is airtight, the bandage is an occlusive dressing. The adhesive is commonly an acrylate, including methacrylates and epoxy diacrylates (which are also known as vinyl resins). [2]

7. Superabsorbent polymer - Wikipedia

   en.wikipedia.org/wiki/Superabsorbent_polymer

   Superabsorbent polymer powder. A superabsorbent polymer (SAP) (also called slush powder) is a water-absorbing hydrophilic homopolymers or copolymers [1] that can absorb and retain extremely large amounts of a liquid relative to its own mass.

8. Membrane roofing - Wikipedia

   en.wikipedia.org/wiki/Membrane_roofing

   Membrane roofing is a type of roofing system for buildings, RVs, ponds, and, in some cases, tanks. It is used to create a watertight covering to protect the interior of a building. Membrane roofs are most commonly made from synthetic rubber, thermoplastic (PVC or similar material), or modified bitumen. Membrane roofs are most commonly used in ...

9. Hydrophobic silica - Wikipedia

   en.wikipedia.org/wiki/Hydrophobic_silica

   Hydrophobic silica displays water resistant properties because of its nanostructure and chemical properties. When applied to a surface of a material, the nanoparticles adhere to the host material and prevent liquids from permeating the rough texture.
