plastics in chemistry

Societal, economic and environmental impacts of plastics.

The usage of plastic merchandises has increased meaningfully in the latest past years, with many initiatives joining the manufacturing and many variations of plastic being manufacture. Therefore the extensive use of plastic merchandises has shortfalls. First is the harmful nature, one-use plastics in packaging food meant for peoples’ consumption containing dangerous compounds (Kelly, 2012). Inappropriate disposal of these packaging foodstuffs results in these hazardous compounds discovering their ways to seawater. They take a very long time to decompose due to their non-biodegradable nature. Scattered plastics are dangerous to animals since they consume them and pass away. Second is the environmental degradation; plastics cannot decompose quickly; subsequently, they might take spans to decay. It is because of the intermolecular connections that organize plastics, whose arrangement makes sure that plastics neither decompose nor corrode. They block waterways and hover on the reservoirs, contaminating and making them unappealing. The third is a low melting point; plastic, in general, has a shallow melting point; hence they cannot be used where temperature levels are high. It also means that they can’t be used as a shielding barrier for the heating system. Some of these plastics products tend to be highly flammable (Andrady, 2011). It, therefore, makes them a fire threat. Fourth is durability; plastic, in general, has a concise, valuable life related to metals. The short life cycle leads to pile-ups of unwanted garbage in the waste yards, office, and homes. Even though some of the plastics are reused, most of them stay uncollected in waste yards and contaminate the environment. Moreover, polyethylene carrier bags are simply carried by windy weather, making it impossible to gather them for recycling.

Polyester is very common in medical field.
Polyethylene terephthalate (PET), polybutylene terephthalate (PBT), and Dacron. Polyesters are produced by reacting terephthalic acid with alcohol. In the case of PET, the alcohol is ethylene glycol, whereas in PBT the alcohol is butylene glycol. Otherwise, the chemistry is similar. Both are semi-crystalline polymers comprised of up to 50% orderly molecular regions (crystals) when cooled from a melt. Polyester fibers and fabrics are tremendously firm. It is very durable: resilient to most chemicals, it can shrink and stretch, wrinkle resilient, abrasion, and mildew resistant. It is quick in drying and hydrophobic naturally (Rowell, 2013). Polyethylene terephthalate (PET) has the best gas blockade properties, and also it’s a chemical resistance excluding the alkalis. It is frequently used for extrusion of sutures, implantable textiles and tubing for angioplasty balloons. Polyester in polybutylene terephthalate (PBT) is more commonly used for injection molded components such as connectors for pulse oximeters, tips for electrosurgical instruments and clips for breathing masks. Polyester dacron is made out of a man-made (synthetic) polyester material. It is used to replace natural body tissues. Most Dacron grafts are in the shape of a tube to replace or repair blood vessels. A Dacron graft can be used as a stent to repair an artery, blood vessel, or other hollow structure in your body (such as the tube that carries urine) to hold it open.
