Thermosetting Plastics

When thermoset plastic is heated for the first time, it can soften and flow, and when heated to a certain temperature, a chemical reaction occurs and cross-chain curing becomes hard. This change is irreversible. After that, when heated again, it can no longer become soft and flow. It is with this characteristic that the molding process is carried out, and the plasticizing flow during the first heating is used to fill the cavity under pressure, and then solidify into a product of defined shape and size. This material is called thermoset plastic. The basic components of thermosetting plastics are polymers of body structure, so they are generally rigid and mostly contain fillers. Industrially important varieties are phenolic plastics, amino plastics, epoxy plastics, unsaturated polyester plastics and silicone plastics, etc.

    Except for the excellent mixing features, both Co-Kneader and twin screw can open the barrel, this is a great advantage to make the thermosetting materials such as BMC, EMC, Melamine, Phenolic Aldehyde and Formaldehyde compounds.
