Thermoplastic molding below melting point
WebbMelting Points and Crystallinity of Molded EPP Samples at Fixed and Moving Mold Surfaces under Different Processing Conditions of Pure Steam and Steam with Hot Air … WebbOverview. Polymers go through several distinct phase transition points at particular temperatures. These transitions induce changes to their specific volume, mechanical properties, and physical state. The most significant thermal transition points include melting (thermoplastics only), and glass transition temperature.
