... PLASTICS are synthetic polymer resins capable of being formed into load-bearing shapes. Thermoplastic materials can be thermal cycled a limited number of times without undergoing irreversible chemical changes. At elevated temperatures, thermoplastics soften and can be molded or extruded into shape...
