Extruder plastic and plastic tri-state of melt-blown cloth machine

There are two major types of plastics: thermosetting and thermoplastic. After the thermosetting plastic is formed and solidified, it cannot be heated and melted. The thermoplastic molded products can be heated and melted to form other products.

With the change of temperature, thermoplastics produce three states of glass state, high elastic state and viscous flow state. With the repeated changes of temperature, the three states produce repeated changes.
