2. Bituminous waterproofing - Wikipedia

   en.wikipedia.org/wiki/Bituminous_waterproofing

   Replacing the roofing felt on a Scout hall in Wales. Bituminous waterproofing systems are designed to protect residential and commercial buildings.Bitumen (asphalt or coal-tar pitch) is a material made up of organic liquids that are highly sticky, viscous, and waterproof. [1]

3. Self-amalgamating tape - Wikipedia

   en.wikipedia.org/wiki/Self-amalgamating_tape

   Self-amalgamating tape is a non-tacky silicone rubber tape that when stretched and wrapped around cables, electrical joints, hoses, and pipes combines or unites itself into a strong, seamless, rubbery, waterproof, and electrically insulating layer. [1] [2] Unlike many other polymers and fibers, it is heat-, sunlight-, and weather-resistant.

4. Polycarbonate - Wikipedia

   en.wikipedia.org/wiki/Polycarbonate

   Polycarbonate is commonly used in eye protection, as well as in other projectile-resistant viewing and lighting applications that would normally indicate the use of glass, but require much higher impact-resistance. Polycarbonate lenses also protect the eye from UV light.

5. Thermoplastic elastomer - Wikipedia

   en.wikipedia.org/wiki/Thermoplastic_elastomer

   Thermoplastic olefins (TPO) are increasingly used as a roofing material. [8] TPEs are also widely used for catheters where nylon block copolymers offer a range of softness ideal for patients. Thermoplastic silicone and olefin blends are used for extrusion of glass run and dynamic weatherstripping car profiles. Styrene block copolymers are used ...

6. Poly(methyl methacrylate) - Wikipedia

   en.wikipedia.org/wiki/Poly(methyl_methacrylate)

   A solution consisting of the polymer in a solvent is used to spin coat silicon and other semiconducting and semi-insulating wafers with a thin film. Patterns on this can be made by an electron beam (using an electron microscope ), deep UV light (shorter wavelength than the standard photolithography process), or X-rays .

7. Butyl rubber - Wikipedia

   en.wikipedia.org/wiki/Butyl_rubber

   It is a harder and less porous material than other elastomers, such as natural rubber or silicone, but still has enough elasticity to form an airtight seal. While butyl rubber will break down when exposed to agents such as NH 3 ( ammonia ) or certain solvents, it breaks down more slowly than comparable elastomers.
