Uses of Plastics Whether you are aware of it or not, plastics play an important part in your life.

Chemical families[ edit ] Examples of organohalogens-chlorides Halocarbons are typically classified in the same ways as the similarly structured organic compounds that have hydrogen atoms occupying the molecular sites of the halogen atoms in halocarbons.

Among the chemical families are: The halogen atoms in halocarbon molecules are often called " substituents ," as though those atoms had been substituted for hydrogen atoms. However halocarbons are prepared in many ways that do not involve direct substitution of halogens for hydrogens.

History and context[ edit ] A few halocarbons are produced in massive amounts by microorganisms. For example, several million tons of methyl bromide are estimated to be produced by marine organisms annually. Most of the halocarbons encountered in everyday life — solvents, medicines, plastics — are man-made.

The first synthesis of halocarbons was achieved in the early s.

Production began accelerating when their useful properties as solvents and anesthetics were discovered. Development of plastics and synthetic elastomers has led to greatly expanded scale of production.

A substantial percentage of drugs are halocarbons. Natural halocarbons[ edit ] A large amount of the naturally occurring halocarbons are created by wood fire, dioxine for example, or volcanic activities. A second large source are marine algae which produce several chlorinated methane and ethane containing compounds.

There are several thousand complex halocarbons known, produced mainly by marine species.

Although chlorine compounds are the majority of the discovered compounds, bromides, iodides and fluorides have also been found. The tyrian purplewhich is a dibromoindigo, is representative of the bromides, while the thyroxine secreted from the thyroid glandis an iodide, and the highly toxic fluoroacetate is one of the rare organofluorides.

These three representatives, thyroxine from humans, tyrian purple from snails and fluoroacetate from plants, also show that unrelated species use halocarbons for several purposes. Organoiodine compounds Organoiodine compounds, called organic iodides, are similar in structure to organochlorine and organobromine compounds, but the C-I bond is weaker.

Many organic iodides are known, but few are of major industrial importance. Iodide compounds are mainly produced as nutritional supplements.

Six mg of iodide a day can be used to treat patients with hyperthyroidism due to its ability to inhibit the organification process in thyroid hormone synthesis, the so-called Wolff-Chaikoff effect. Prior toiodides were the predominant antithyroid agents. In large doses, iodides inhibit proteolysis of thyroglobulinwhich permits TH to be synthesized and stored in colloidbut not released into the bloodstream.Chess Plastics is a plastic injection moulder very focused on understanding the needs of our customers.

Custom Plastics Injection Molding. GEMINI PLASTICS is a family owned corporation serving customers worldwide since Our goal is to provide our customers with leading edge technology, a commitment to continuous improvement and “one stop shopping” to handle all of your prototype, production and value added requirements.. Quality driven proven results. IMPORTANCE OF PLASTIC: Plastics are a subset of materials known as Polymers. These are composed of large molecules formed by joining many smaller molecules together (monomers). Other kinds of polymers are fibres, elastomers, surface coating and biopolymers, such as cellulose, proteins and nucleic acids. bending. Our strip heaters allow us to take a sheet of clear or colored material, up to 3/4" in thickness, and bend along a heated line. This provides a consistent and professional bend when working with many different types of material.

Igbuzor () in stressing the importance of education stated that education is a human right that should be accorded to all human beings solely by reason of being human. This paper aims to investigate some of the hottest issues that concern the increasing presence of plastics in the sea.

In an attempt to identify the main knowledge gaps and to suggest future research, we discuss priority topics on marine plastic pollution through ten thought-provoking questions on the current knowledge of multiple consequences of plastics on the marine ecosystem.

Importance of plastics

Jul 27,  · The success of plastics as a material has been substantial; they have proved versatile for use in a range of types and forms, including natural polymers, modified natural polymers, thermosetting plastics, thermoplastics and, more recently, biodegradable plastics.

Most modern plastics are based on organic chemicals which offer a huge range of physical properties to manufacturers — the range of formulations is vast and still growing. There was a time when anything made of plastic was considered to be of inferior quality, but those days are past. You are.
