Study on the Properties and Applications of Thermoplastic

Abstract

Hot-applied thermoplastic is prepared for road deposition in a melting apparatus where the granular or block material is introduced and heated until it liquefies at temperatures exceeding 400F. When applied on asphaltic concrete, thermoplastic material develops a thermal bond via heat- fusion. A thermoplastic is a material, usually a plastic polymer, which becomes soft when heated and hard when cooled. Thermoplastic materials can be cooled and heated several times without any change in their chemistry or mechanical properties. When thermoplastics are heated, they melt to a liquid. A thermoplastic, or thermosoftening plastic, is a plastic material, a polymer, which becomes pliable or moldable above a specific temperature and solidifies upon cooling. Most thermoplastics have a high molecular weight. Thus, thermoplastics may be reshaped by heating and are typically used to produce parts by various polymer processing techniques such as injection molding, compression molding, calendaring, and extrusion. They are useful for a variety of applications, including consumer goods, machine parts, medical equipment and packaging and storage materials. Each type of material offers different properties, benefits and strengths; and today, we are going to focus on the importance of thermoplastic materials.
