  2. Plastic compounding - Wikipedia

    en.wikipedia.org/wiki/Plastic_compounding

    Co-kneaders and twin screws (co- and counter rotating) as well internal mixers are the most common used compounders in the plastic industry. [3] The extrudate, which look like long plastic strands, are then cooled in a water bath, or by spraying as the conveyor belt moves it to the granulator. The granulator breaks the strands into the desired ...

  3. Polymer chemistry - Wikipedia

    en.wikipedia.org/wiki/Polymer_chemistry

    Polymer chemistry is a sub-discipline of chemistry that focuses on the structures of chemicals, chemical synthesis, and chemical and physical properties of polymers and macromolecules. The principles and methods used within polymer chemistry are also applicable through a wide range of other chemistry sub-disciplines like organic chemistry ...

  4. Polymer engineering - Wikipedia

    en.wikipedia.org/wiki/Polymer_engineering

    Polymer engineering is generally an engineering field that designs, analyses, and modifies polymer materials. Polymer engineering covers aspects of the petrochemical industry, polymerization, structure and characterization of polymers, properties of polymers, compounding and processing of polymers and description of major polymers, structure property relations and applications.

  5. Polymer science - Wikipedia

    en.wikipedia.org/wiki/Polymer_science

    Polymer science or macromolecular science is a subfield of materials science concerned with polymers, primarily synthetic polymers such as plastics and elastomers. The field of polymer science includes researchers in multiple disciplines including chemistry , physics , and engineering .

  6. Masterbatch - Wikipedia

    en.wikipedia.org/wiki/Masterbatch

    The additives in a masterbatch are chosen to impart desired physical property changes to a final plastic product. They can increase volumetric output due to thermal conductivity and volumetric expansion at a given temperature as well as potentially increasing the toughness, flexural stiffness, adhesion, and printability of a final product. [6]

  7. Polymer nanocomposite - Wikipedia

    en.wikipedia.org/wiki/Polymer_nanocomposite

    Polymer nanostructured fibers, core–shell fibers, hollow fibers, and nanorods and nanotubes provide a platform for a broad range of applications both in material science as well as in life science. Biological objects of different complexity and synthetic objects carrying specific functions can be incorporated into such nanostructured polymer ...

  8. Styrene maleic anhydride - Wikipedia

    en.wikipedia.org/wiki/Styrene_maleic_anhydride

    SMA polymers with a high molecular weight are widely used in engineering plastic applications, normally in the impact modified and optional glass fibre filled variants. Alternatively, SMA is applied using its transparency in combination with other transparent materials like PMMA or the heat resistance to heat-boost other polymers materials like ...

  9. Polymer stabilizer - Wikipedia

    en.wikipedia.org/wiki/Polymer_stabilizer

    Stabilizers are used at all stages of the polymer life-cycle. They allow plastic items to be produced faster and with fewer defects, extend their useful lifespan, and facilitate their recycling. [1] However they also continue to stabilise waste plastic, causing it to remain in the environment for longer. Many different types of plastic exist ...
