  2. 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.

  3. Plastics in the construction industry - Wikipedia

    en.wikipedia.org/wiki/Plastics_in_the...

    Plastic is the generic name for a family of synthetic materials derived from petrochemicals.It is often product of two or more components. There are many families of plastics and polymers being used in construction industry, such as acrylics, composites, expanded polystyrene, polycarbonates, polyethylene, polypropylene, and polyvinyl chloride.

  4. Twinwall plastic - Wikipedia

    en.wikipedia.org/wiki/Twinwall_plastic

    Twinwall plastic most commonly refers to two exterior plastic sheets that are connected with a plastic support layer to create parallel channels. This design adds both impact toughness and the ability to support weight. Twinwall plastic may also be used to describe a pipe that has a smooth interior with exterior air filled ridges. [3]

    T-beams are similar to double tees but can be used for span ranging from 30 feet (9.1 m) to 100 feet (30 m). Joists and planks are combination of using prestressed joists with prestressed planks. Keystone-shape joists can be used for up to 36-foot (11 m) spans and tee-shape joists can be used for up to 60-foot (18 m) span.

  7. Plastic optical fiber - Wikipedia

    en.wikipedia.org/wiki/Plastic_optical_fiber

    Plastic optical fiber (POF) or polymer optical fiber is an optical fiber that is made out of polymer. Similar to glass optical fiber, POF transmits light (for illumination or data) through the core of the fiber. Its chief advantage over the glass product, other aspect being equal, is its robustness under bending and stretching.

  8. Polymer concrete - Wikipedia

    en.wikipedia.org/wiki/Polymer_concrete

    In polymer concrete, thermoplastic polymers are often used, [2] but more typically thermosetting resins are used as the principal polymer component due to their high thermal stability and resistance to a wide variety of chemicals. Polymer concrete is also composed of aggregates that include silica, quartz, granite, limestone, or other material.

  9. Superplasticizer - Wikipedia

    en.wikipedia.org/wiki/Superplasticizer

    The polymers used as plasticizers exhibit surfactant properties. They are often ionomers bearing negatively charged groups ( sulfonates , carboxylates , or phosphonates ...). They function as dispersants to minimize particles segregation in fresh concrete (separation of the cement slurry and water from the coarse and fine aggregates such as ...
