  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. Photo-oxidation of polymers - Wikipedia

    en.wikipedia.org/wiki/Photo-oxidation_of_polymers

    Photo-oxidation causes the polymer chains to break (chain scission), resulting in the material becoming increasingly brittle. This leads to mechanical failure and, at an advanced stage, the formation of microplastics. In textiles, the process is called phototendering. Technologies have been developed to both accelerate and inhibit this process.

  4. List of materials properties - Wikipedia

    en.wikipedia.org/wiki/List_of_materials_properties

    A material property is an intensive property of a material, i.e., a physical property or chemical property that does not depend on the amount of the material. These quantitative properties may be used as a metric by which the benefits of one material versus another can be compared, thereby aiding in materials selection.

  5. Crystallization of polymers - Wikipedia

    en.wikipedia.org/wiki/Crystallization_of_polymers

    As done in crystalline materials, particles can be added to semi-crystalline polymers to change the mechanical properties. In crystalline materials the addition of particles works to impede dislocation motion and strengthen the material. However, for many semi-crystalline polymers particle fillers weaken the material.

  6. Twinwall plastic - Wikipedia

    en.wikipedia.org/wiki/Twinwall_plastic

    Twin-wall plastic, specifically twin-wall polycarbonate, is an extruded multi-wall polymer product created for applications where its strength, thermally insulative properties, and moderate cost are ideal. [1] Polycarbonate, which is most commonly formed through the reaction of Bisphenol A and Carbonyl Chloride, is an extremely versatile ...

  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.

  8. Poly(trimethylene carbonate) - Wikipedia

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

    Low molecular weight PTMC is a rubbery polymer with poor dimensional stability, tackiness, and inadequate mechanical properties. Nevertheless, high molecular weight amorphous PTMC (over 100,000) is very flexible, with a relatively low elastic modulus (5–7 MPa) at room temperature, tough and it presents excellent ultimate mechanical properties.

  9. Polymer matrix composite - Wikipedia

    en.wikipedia.org/wiki/Polymer_matrix_composite

    In particular carbon nanotubes have some of the highest measured tensile stiffnesses and strengths of any material due to the strong covalent sp 2 bonds between carbon atoms. However, in order to take advantage of the exceptional mechanical properties of the nanotubes, the load transfer between the nanotubes and matrix must be very large.
