These monomers are then polymerized into chains called polymers, or plastic resin, such as polyethylene and polypropylene, in their most basic forms. The major types of thermoplastics include polyethylene, polyvinyl chloride, polypropylene, polystyrene, polyester and a range of specialized engineering resins. Global Business Director, Polypropylene, The Dow Chemical Company, May 2007 to March 2008.

Available in North America, injection-moldable reSound™ R VX TPEs utilize 25% (PCR) and up to 40 percent (PIR) recycled content, and both grades can be overmolded onto polypropylene (PP). This masterbatch was necessary for the manufacture of melt-blown non-woven polypropylene used to make the protective face masks with long-lasting filtration properties.
