| Trifluoride ethylene resin | Polyarylsulfone | ・Thermosetting resin : Heated at 80 °C, it becomes sticky paste with fluidity. Then it is injected into the mold under pressure. Once hardened, the plastics does not get soft owing |

Polyethylene ・Thermoplastic resin : As temperature rises, this resin becomes soft → gammy → fluidity liquid. For example, polystyrene (PS) is like glass at normal temperature. From 80°C and higher its elastic modules decreases, from 110°C it becomes gammy, and higher than 170°C, it becomes sticky paste.
