Plastics refer to a wide collection of materials, both semi-synthetic and synthetic organic compounds, which are moldable and malleable into solid items. Typically, plastics are organic polymer containing high molecular masses, but they may contain other substances too. Most are synthetic derivatives from petrochemicals, but some are natural partially. Plastics manufacturing is relatively cheap and easy. Additionally, the substances are impervious and versatile.
The many advantages that plastics present to manufacturers have seen them being adopted in the production of a huge and growing number of products. Their use ranges from the production of the simplest of household products to spaceships and rockets. Most traditional materials that dominated the manufacturing industry such as leather, metal, paper, ceramic, glass, bone, wood, horn, and stone are continuously being replaced.
In countries that are highly developed, a third of all packaging materials are made from plastics while another third is used to make building materials. Other industries in which this materials is used heavily include furniture, toys, and automobile. There is a lot of variance in the extent to which plastic is used among underdeveloped, developing, and developed nations. However, use in developing nations is rising at a steady rate to cover the gap between them and developed nations. These materials also finds heavy use in the field of medicine.
Currently, there are several different types of plastics used for making different products. Some common types include polyester, polyethylene terephthalate, polyethylene, high-density polyethylene, polyvinyl chloride, polyvinylidene chloride, low-density polyethylene, polypropylene, polystyrene, high impact polystyrene, polyamides, polycarbonates, polyurethanes, and acrylonitrile butadiene styrene. Fibers and textiles are manufactured from polyester. Polyethylene terephthalate is used to make bottles for carbonated drinks, plastic films, peanut butter jars, and microwavable packaging.
Many inexpensive commodities are manufactured from polyethylene. Some major examples include plastic bottles and shopping bags. Shower curtains, flooring, guttering, window frames, and plumbing pipes are some of the products manufactured from polyvinyl chloride. Packaging of foods in the modern market is done using materials made from polyvinylidene chloride. Polycarbonate makes riot shields, compact discs, lenses, eyeglasses, security windows, and traffic lights. Multiple classes of products are made from one type of plastic in some cases.
The description of the characteristics of plastic materials is based on the organic chemistry of the polymer it is made out of. Some common descriptors include oxidation, density, hardness, heat resistance, organic solvents, and ionizing radiation among many others. Even though plastic materials can be turned into electrical conductors, their level of electrical conductivity remains very low when compared to that of metals.
Pure plastics are only toxic to a very low level. This is because they are biochemically inert and they do not dissolve in water. The large molecular weights are responsible for biochemical inertness. Toxicity in products manufactured from plastic usually results from the additives added into the material. The leaching activity of the additives are responsible for toxicity.
As a result of toxicity, some countries enforce certain laws on the kind of additives that can be added in certain products. Plastic materials also degrade at a very low rate. Their chemical composition makes them resistant to most natural degradation processes.
