2. Bituminous waterproofing - Wikipedia

   en.wikipedia.org/wiki/Bituminous_waterproofing

   Bitumen (asphalt or coal-tar pitch) is a material made up of organic liquids that are highly sticky, viscous, and waterproof. [1] Systems incorporating bituminous-based substrates are sometimes used to construct roofs , in the form of "roofing felt " or "roll roofing" products.

3. Flashing (weatherproofing) - Wikipedia

   en.wikipedia.org/wiki/Flashing_(weatherproofing)

   Types of flexible flashing products are rubberized asphalt, butyl rubber, polyvinylidene fluoride (sometimes known as kylar or hylar), and acrylic. [9] The different types have different application temperature ranges, material adhesion compatibility, chemical compatibility, levels of volatile organic compounds , and resistance to ultraviolet ...

4. Butyl rubber - Wikipedia

   Rubberized asphalt concrete (RAC), also known as asphalt rubber or just rubberized asphalt, is noise reducing pavement material that consists of regular asphalt concrete mixed with crumb rubber made from recycled tires. Asphalt rubber is the largest single market for ground rubber in the United States, consuming an estimated 220,000,000 pounds ...

6. Acrylate polymer - Wikipedia

   en.wikipedia.org/wiki/Acrylate_polymer

   Acrylic elastomer is a general term for a type of synthetic rubber whose primary component is acrylic acid alkyl ester (ethyl or butyl ester). [3] Acrylic elastomer possesses characteristics of heat and oil resistance, with the ability to withstand temperatures of 170–180 °C. It is used primarily for producing oil seals and packaging related ...

7. Bitumen - Wikipedia

   en.wikipedia.org/wiki/Bitumen

   Mastic asphalt is a type of asphalt that differs from dense graded asphalt (asphalt concrete) in that it has a higher bitumen content, usually around 7–10% of the whole aggregate mix, as opposed to rolled asphalt concrete, which has only around 5% asphalt. This thermoplastic substance is widely used in the building industry for waterproofing ...
