The primary component of plastics is the resin. The term resin is derived from the lipids secreted by plants and animals, such as rosin, shellac, etc. Resins are polymers that have not been mixed with various additives.

The primary component of plastics is the resin. The term resin is derived from the lipids secreted by plants and animals, such as rosin, shellac, etc. Resins are polymers that have not been mixed with various additives. Resin accounts for about 40% to 100% of the total weight of the plastic. The properties of plastics are determined primarily by the properties of the resin, but additives also play an important role. Some plastics are basically composed of a constituent resin with no or little additives, such as plexiglass, polystyrene, and the like. The so-called plastic, which is originally one of the constituent resins, has a shape similar to that of a natural resin, but is called a plastic because it is artificially composed by a chemical method.
First, the definition
According to the definition of the American Association of Data Experiments, plastic is a material with high molecular weight organic matter as the primary component. It has a solid shape at the end of processing, and can be flowed during production and processing. Appearance.
Therefore, through this clarification we can get the following understanding:
(1) It is a polymer organic compound
(2) It can exist in various types such as liquid solid colloidal solution, etc.
(3) It can be shaped (moldable)
(4) The variety is complex, because different monomers and their components can form different plastics
(5) Diversification of a wide range of commodities
(6) has different properties
(7) Can use different processing methods (processing method)
The terms plastic and resin are also often used.
Second, plastic can be divided into thermosetting and thermoplastics. The former cannot be used from the beginning, and the latter can be repeated. There are two types of plastic polymer structures: the first is a linear structure; the second is a bulk structure.
Molecular structure classification of polymers:
Granule
(a) Linear construction
(b) Linear construction (with branches)
(c) Mesh structure (small cross-linking between molecular chains)
(d) Body structure (many crosslinks between molecular chains)
Two different structures, linear structure (including branched structure) high polymer due to the existence of independent molecules, it is elastic, soluble in the solvent, so there is no elasticity and plasticity, can not dissolve.
Table 1.1 is a comparison table of plastic raw materials, items 1 to 8 are general-purpose plastics, and items 9.10 are somewhere in between. Usually referred to as PP, HDPE, LDPE, PVC and PS are five general-purpose plastics.
Third, plastic raw materials
The plastic raw material is said to be a composition or a natural polymer compound, which can be arbitrarily kneaded into various shapes to finally maintain the shape of the data or plastic materials.
