A CDE Definition
A polymer-based liquid or powder that becomes solid when heated, placed under pressure, treated with a chemical or via radiation. The curing process creates a chemical bond that, unlike a thermoplastic, prevents the material from being remelted. See thermoplastic.
A polymer material that becomes pliable with heat, and with sufficient temperature, a liquid. When cooled, thermoplastics return to solid. There are more than 40 types, including acrylic, polypropylene, polycarbonate and polyethylene. Dating back to the mid-1800s, celluloid was the first thermoplastic, which remained popular until the mid-1900s. See thermoset and 3D printing.
