    Is there anyone, that can explan why the melting and crystallization peak of a plastic don not have same position in DSC scan?

    Hi there
    Well i don`t know if it is the same for plastic as for metals but for metals this a normal effect if you mean that it crystalizes at a lower temperature then it melts.

    I don`t know the physical reason for it perfectly but it has to do with the state of lowest energy. Thought it can be influenced by some parameters like cooling rate and such.
