As we all know, the buttons are made of a variety of materials, one of which is the resin buttons. Then, what kind of resin can be divided into? The following is a description of the related classification of resin by the China Button Industry Network Xiaobian. I hope to bring you convenience and help.
1. According to the classification of resin synthesis reaction According to this method, the resin can be divided into addition polymer and polycondensate. Addition polymer refers to a polymer obtained by addition polymerization reaction. The chemical structure of the chain segment structure is the same as that of the monomer, such as polyethylene, polystyrene, polytetrafluoroethylene, and the like.
The polycondensate refers to a polymer obtained by a condensation polymerization reaction. The chemical formula of the structural unit is different from the molecular formula of the monomer, such as a phenolic resin, a polyester resin, a polyamide resin, and the like.
2, according to the resin composition of the main chain composition According to this method, the resin can be divided into carbon chain polymer, hetero-chain polymer and elemental organic polymer.
The carbon chain polymer refers to a polymer in which the main chain is entirely composed of carbon atoms, such as polyethylene, polystyrene, and the like.
Heterochain polymers are polymers in which the main chain consists of carbon and oxygen, nitrogen, sulfur, and other two or more elements, such as polyoxymethylene, polyamide, polysulfone, polyether, and the like. The elemental organic polymer means that the main chain does not necessarily contain carbon atoms and is mainly composed of atoms such as silicon, oxygen, aluminum, titanium, boron, sulfur, and phosphorus, such as organic silicon.
The above is about the classification of resin materials, I believe you have a new understanding of resin buttons.
