Although PMMA is often called simply "acrylic", acrylic can also refer to other polymers or copolymers containing polyacrylonitrile. Notable trade names include Acrylite, Lucite, R-Cast, Plexiglas, Optix, Perspex, Oroglas, Altuglas, Cyrolite, and Sumipex.
PC is commonly used for plastic lenses in eyewear, in medical devices, automotive components, protective gear, greenhouses, Digital Disks (CDs, DVDs, and Blu-ray), and exterior lighting fixtures. Polycarbonate also has very good heat resistance and can be combined with flame retardant materials without significant material degradation.
Polylactic Acid is principally made through two different processes: condensation and polymerization. The most common polymerization technique is known as ring-opening polymerization. This is a process that utilizes metal catalysts in combination with lactide to create the larger PLA molecules.
Polypropylene vs PVCA brief look at some environmental issues. There are significant intrinsic differences between polyvinyl chloride (PVC) and polypropylene (PP). Polypropylene is one of the most neutral plastics, containing only two elements: carbon (C) and hydrogen (H).
Polystyrene is commonly injection molded, vacuum formed, or extruded, while expanded polystyrene is either extruded or molded in a special process. Polystyrene copolymers are also produced; these contain one or more other monomers in addition to styrene.
