Structure and Properties of Crystalline and Non - crystalline Polymers in Plastic Molds

Now the weather is the summer Mayday, Dongguan Plastic mold factory of the majority of your colleagues in your production workshop hot, I believe that all colleagues want their work environment cool and cool it, the editor also said that a good working environment is able to greatly Improve efficiency. Today will introduce the plastic mold in the crystalline and non-crystalline polymer structure and performance.


(A) the definition of crystallization


     Crystallization refers to the polymer from the molten state to the condensation, the molecules from the independent movement, completely in an orderly state into a molecular stop free movement, to obtain a slightly fixed position, and have a tendency to make themselves a regular model of the tendency of a Phenomenon.


(B) the definition of crystalline and non-crystalline


  1, crystal type


     Polymer from the high temperature melt to low temperature solid state transition process, if the molecular chain can be stable and regular arrangement, known as the crystal type.


  2, the polymer from high temperature melt to low temperature solid state transition process, if the molecular chain can not get a regular arrangement, known as non-crystalline type.
