Polyethylene, polypropylene, polyvinyl chloride, polystyrene, polybenzimidazole, acrylic, nylon and Teflon are examples of thermoplastics. Thermo-softening plastic, or thermoplastic, becomes soft and flexible at a certain temperatures and solidifies on cooling.
Thermoplastics can be drawn into fibers, films or packaging. Polyethylene is the thermoplastic used in Ziploc storage bags. Styrofoam is made by heating polystyrene and blowing air through the mixture. Polyvinyl chloride is used in pipes and plumbing and is known for its durability. Teflon is strong, stable and heat-resistant; it is used in cookware, plumbing tape, waterproof coatings, films and bearings. Polypropylene is used in bottles, tubes, filaments, bags, battery cases and car trim.
