The chemical composition of plastic.

Now let me explain the chemical composition of plastics. I'm glad to be able to help you. Let's start. Plastics are divided into polypropylene, polyethylene, polyvinyl chloride, and polystyrene. The chemical composition of each plastic is different and contains ethylene, propylene, vinyl chloride, and styrene respectively after polymerization.

What are the chemical components of plastic? The chemical components of plastic are plasticizers, stabilizers, and lubricants. Plastic is a high polymer compound formed by polymerization or condensation reactions using monomers as raw materials. Its ability to resist deformation is moderate, between fibers and rubber. It is composed of synthetic resins and additives such as fillers, plasticizers, stabilizers, lubricants, and colorants.

The main component of plastic is resin. Resin refers to a polymer compound that has not been mixed with various additives. The term resin originally referred to lipids secreted by animals and plants, such as rosin and insect glue. Characteristics: Plastics can be divided into two categories: thermosetting and thermoplastic. The former cannot be reshaped and reused, while the latter can be reproduced repeatedly. Thermoplastic materials have a higher physical elongation rate, generally ranging from 50% to 500%. The force does not change linearly under different elongation rates.

The different properties of plastics determine their uses in daily life and industry. With the advancement of technology, research on plastic modification has never stopped. It is hoped that in the near future, modified plastics can have a wider range of applications, and even replace materials such as steel and no longer pollute the environment. The above content is referenced from "Plastics".

The composition elements of plastic Plastic is a synthetic polymer composed of hydrocarbons (mainly olefins) and hydrocarbon derivatives. It can also be referred to as macromolecules or polymers. It mainly consists of carbon (C) and hydrogen (H), with some plastics also containing oxygen (O), chlorine (Cl), sulfur (S), and nitrogen (N). For example, common plastics such as polypropylene, high-density polyethylene, low-density polyethylene, linear low-density polyethylene, general-purpose polystyrene, foamed polystyrene, impact-resistant polystyrene, and polyoxymethylene only contain carbon (C) and hydrogen (H). Polyamides (nylon), acrylonitrile-butadiene-styrene copolymers, and styrene-acrylonitrile copolymers contain carbon (C), hydrogen (H), and nitrogen (N). Poly(methyl methacrylate), poly(ethylene terephthalate), and poly(butylene terephthalate) contain carbon (C), hydrogen (H), and oxygen (O). Poly(phenylene sulfide) contains carbon (C), hydrogen (H), oxygen (O), and sulfur (S). Poly(ethyl methacrylate) contains carbon (C), hydrogen (H), oxygen (O), and nitrogen (N).

Chemical Composition of Plastics 1. Plastics are high molecular weight compounds formed by the polymerization of monomers through addition or condensation reactions. They have moderate deformation resistance, falling between fibers and rubber. They are composed of synthetic resins and fillers, plasticizers, stabilizers, lubricants, pigments, and other additives.

2. The main component of plastic is resin. Resin refers to a polymer compound that is not mixed with various additives. The term resin was originally named after the secretion of lipids from animals and plants, such as rosin and insect glue. Resin accounts for 40% to 100% of the total weight of plastic. The basic performance of plastic mainly depends on the nature of the resin, but additives also play an important role. Some plastics are basically composed of synthetic resins, without or with only a small amount of additives, such as acrylic.
