How to Select Thermoplastics and Thermoplastic Materials Thermoplastics and thermoplastic materials are polymers that turn to liquid when heated and turn solid when cooled. They can be repeatedly remelted and remolded, allowing parts and scraps to be reprocessed. In most cases they are also very recyclable. Types of Thermoplastic Chemical Systems Thermoplastics are based upon a variety of chemical systems listed in the GlobalSpec SpecSearch Database. The most important ones include polyvinyl...
