According to the sources of resin can be divided into natural resin and synthetic resin. Natural resin is obtained from nature's animals and plants discharge amorphous organic material, such as rosin, amber, shellac, etc. Synthetic resin is through a simple organic chemical synthesis or natural products chemistry and resin products, such as phenolic resin, PVC resin, etc. , in which synthetic resin is the main ingredient in plastics. According to the synthesis of such, resin can be divided into addition polymer and condensation polymer. Addition polymer refers to through the preparation of polymer addition polymerization. The chemical formula which best characterizes the chain structure and monomer formula is the same, such as polyethylene, polystyrene, teflon, etc. Polycondensate refers to the preparation of polymer by polycondensation. Formula of the chemical formula which best characterizes the structural unit is different from the monomer, such as phenolic resin, polyester resin, polyamide resin, etc. Composed according to the method, the molecular skeleton resin can be divided into carbon chain polymers, heterochain polymers and element organic polymer. Carbon chain polymer is refers to the main chain of carbon atoms entirely by polymer, such as polyethylene, polystyrene, etc. Heterochain polymers is refers to the main chain consists of two or more atoms of polymers, described elements such as carbon and oxygen, nitrogen and sulfur, such as polyoxymethylene, polyamide, polysulfone and polyether. Element organic polymer is not included in the main chain of carbon atoms, and is mainly composed of such as silicon, oxygen, aluminum, titanium, boron, sulfur and phosphorus elements, such as atoms, such as silicone. According to the production of thermosetting resin ( These resins are generally used in FRP) : unsaturated polyester/vinyl ester/epoxy/phenolic resin/double maleic imide ( BMI) / polyimide resin. Thermoplastic resin, polypropylene ( PP) / polycarbonate ( PC) / nylon ( NYLON) / polyether ether ketone ( PEEK) / poly (ether sulfone) ( PES) 。 Synthetic resin is a kind of synthetic polymers. Synthetic resin is the most important application in the manufacturing of plastics. In order to promote the processing and improve performance, often adding additives, sometimes they are directly used for processing and forming, so they usually is synonymous with plastic. Synthetic resin was used in the manufacture of synthetic fibers, coatings, adhesives, insulation materials and other basic materials. There are various kinds of synthetic resin polyethylene ( PE) Polyvinyl chloride ( PVC) Polystyrene ( PS) The polypropylene ( PP) And ABS resin is the most common five kinds of resin, which is the most widely used synthetic resin material. Resin handicraft resin material used in this set of molding materials for arts and crafts. The smoothness of line and bright texture make full use of the advantage of its material.
