How Much Is The Melting Point Of A Plastic Triangle
Plastic products are organic, non crystal, not suitable for the definition of melting point, so there is no melting point.
The melting point is the temperature that the solid transforms its state from the solid to the liquid. The temperature of the opposite action, which is turned from the liquid to the solid, is called the freezing point. Unlike the boiling point, the melting point is less affected by the pressure.
