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.Learn More
Examples of reversible changes include melting chocolate and changing it back into a solid by cooling it, and melting candle wax by heating it and solidifying the wax by cooling it. Reversible changes are changes that can be reversed. They are also known as physical changes.Full Answer >
Energy transformation is the change of energy from one form to another. For example, a ball dropped from a height is an example of a change of energy from potential to kinetic energy.Full Answer >
The best thermal conductors are generally metals and take the shape of pans, appliances, pipes and other commercial and residential fixtures. Thermal conductors are essentially items that transport heat from one place to another. Heat is a type of thermal energy, which is transferred through several methods, including convection, radiation and conduction.Full Answer >
Thermoplastics are a subset of plastics that can be re-shaped with the application of pressure and heat multiple times. Different types of thermoplastics have additional properties that make them especially well-suited to different jobs, but all thermoplastics share the same characteristic of flexibility when exposed to heat and force.Full Answer >
