Unlike rubber and PVC, drop molding is a new molding process for small equipment, mainly producing trademarks, nameplates, lace patterns, small accessories, etc. The materials used for drop molding are two-component sodium silicate, organic glass and PVC. Sodium silicate is salt, plexiglass and PVC are plastic, but not rubber. Rubber cannot be used as a plastic injection material and is often mistaken for rubber, a soft PVC plastic injection material with a similar appearance. The difference between drop molding materials and PVC is that drop molding materials can use PVC, but the material is not the only one. Only a certain type of PVC is suitable for making plastic materials, but its main uses are pipes, plates, profiles, and films.
1. Different uses. Drop molding is a new small device molding process, mainly producing trademarks, nameplates, lace patterns, small accessories, etc. The main uses of polyvinyl chloride are to manufacture pipes, plates, profiles, films, wires, cables, etc.
2. The materials are different. The materials used for drop molding are two-component sodium silicate, organic glass and PVC. Sodium silicate is a salt, while Plexiglas and PVC are plastics, not rubber. Rubber cannot be used as a drop molding material and is often mistaken for a soft PVC drop molding material that looks similar to rubber.
3. Contains relationships. The plastic material can be PVC, but the material is not the only one. Only certain types of PVC are suitable for plastic injection.
The technology of drop molding is that the thermoplastic polymer material has a variable state characteristic, that is, it is viscous under certain conditions, but can return to a solid state at room temperature. It uses appropriate methods and special tools to inkjet, in which In the viscous state, it is molded into the designed shape as required, and then solidified at room temperature.
Polyvinyl chloride (PVC) is the initiator of vinyl chloride monomer (VCM) in peroxides and azo compounds. Or polymers polymerized under the action of light and heat according to the free radical polymerization mechanism. Homopolymers and copolymers of vinyl chloride are collectively called vinyl chloride resins.
