WebThermoplastic. A thermoplastic is a material, usually a plastic polymer, which becomes more soft when heated and hard when cooled. Thermoplastic materials can be cooled and heated several times without any change in their chemical or mechanical properties. When thermoplastics are heated to their melting point, they melt to a liquid. WebPMMA, polymethyl-methacrylate, is a thermoplastic acrylic linear polymer, the mer of which is illustrated in the diagram. PMMA is transparent, with a refractive index of 1.49, and easily formed into optical components. It is also used as a photoresist material in the fabrication of semiconducting devices.
