Thermoplastic (Thermo plastics): refers to melt when heated, can flow to the mold cooling, heat will melt the plastic; use of heating and cooling, to produce irreversible changes (← → liquid solid), is called a physical change. Common thermoplastics their continuous working temperature: 100 ℃ below, polyethylene, PVC, polypropylene, polystyrene and known as the four common plastics. Thermoplastic plastics and hydrocarbons, polarity gene-containing vinyl, engineering, cellulose and other types. Time-variant soft heated, cooling time-varying, and cyclic softening and hardening and keep a certain shape. Soluble in certain solvents, which can melt properties of soluble. Thermoplastics with excellent electrical insulation, especially polytetrafluoroethylene (PTFE), polystyrene (PS), polyethylene (PE), polypropylene (PP) has a very low dielectric constant and dielectric loss, suitable for high frequency and high voltage insulation materials.
