Description
A polymer that can be melted with heat then molded multiple times. Thermoplastic polymers are typically soluble in various organic solvents. Examples of thermoplastic polymers are Vinyl resins, Acrylics, Polyethylene, Polystyrene, Cellulose acetate, Polyamides along with some Polyesters and Polyurethanes. Polymers that cannot be melted are called thermosets.
