The Elements of Plastics

The plastics that we usually use is not a pure compound. It is made by the preparing of many components, in which the high polymer (or synthetic resin) is its major ingredient. In addition, in order to enhance the performance of plastics, a selection of auxiliary supplies must also be included in the polymer, this kind of as fillers, plasticizers, lubricants, stabilizers, coloring agents, and so on, so as to make the plastics have great overall performance.

Very first, synthetic resin
Artificial resin is the principal part of plastics. The standard content of synthetic resin in plastics is from forty% to a hundred%. Since of its big content, the character of artificial resin frequently decides the character of the plastics, so people typically consider resin as a synonym of plastics. In fact, resin and plastics are two distinct concepts. Resin is a raw polymer which has not been processed. Even though for most plastics, apart from the resin as its principal element, there are also some other substances.

Next, fillers
Fillers can improve the power and heat-resistant high quality of the plastics, as nicely as decrease the expense. For example, adding wood flour into phenolic resin can greatly minimize the cost, which tends to make the phenolic plastic as a single of the least expensive plastics. At the same time, it can also considerably increase the mechanical strength. Fillers can be divided into organic filler and inorganic filler, with the former as wooden flour, rags, paper and all varieties of textile fibers, and the latter as glass fibers, diatomaceous earth, asbestos, and carbon black.

Third, สายรัดพลาสติก can increase the plasticity and adaptability of the plastics, minimize brittleness, and make the plastics easy to be processed and molded. Plasticizers are normally natural compounds with substantial boiling point, miscible with the resin, non-toxic, odorless, and stable to gentle and heat. The generally utilized plasticizers include phthalates, benzophenone, and so on.
