Plastic classification of plastic mold injection

  •  

    According to the molecular structure and characteristics of synthetic resins, it is divided into thermoplastics and thermosetting plastics.Plastic Manufacturers , Thermoplastics: The molecular structure of synthetic resins in these types of plastics is linear or branched.

     

    Thermoset Plastics: The molecular structure of the resin in this type of plastic is ultimately a bulk structure. It has a linear structure at the beginning of heating. Therefore, it is malleable and soluble, and can be molded into shaped plastic parts.

     

    When the heating is continued, chemical bonds (ie, cross-links) are formed between the main chains of the linear molecules, and the molecules become a network structure. When the temperature reaches a certain value, the cross-linking reaction further develops, and the molecule finally becomes a bulk structure. Non-melting and non-melting, the shape of plastic parts is fixed.
