  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. 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 ...

  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]

  5. 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 ...

  6. Plastic extrusion - Wikipedia

    en.wikipedia.org/wiki/Plastic_extrusion

    A common post-extrusion process for plastic sheet stock is thermoforming, where the sheet is heated until soft (plastic), and formed via a mold into a new shape. When vacuum is used, this is often described as vacuum forming. Orientation (i.e. ability/ available density of the sheet to be drawn to the mold which can vary in depths from 1 to 36 ...

  7. Polymer solution casting - Wikipedia

    en.wikipedia.org/wiki/Polymer_solution_casting

    The most notable attribute of this thin-film process technology is the ability to alternate the material properties (i.e. strength, durometer, color, lubricity) amongst the individual layers or even down the length of the part, resulting in a feature-rich single-piece construction. This process also allows other components to be incorporated ...

  9. Polymer concrete - Wikipedia

    en.wikipedia.org/wiki/Polymer_concrete

    The exact properties depend on the mixture, polymer, aggregate used etc. [6] Generally speaking with mixtures used: The binder is more expensive than cement; Significantly greater tensile strength than unreinforced Portland concrete (since polymer plastic is 'stickier' than cement and has reasonable tensile strength) [1]
