ADVANTAGES Plastic is very useful in the building and construction‚ electronics (laptops wouldn’t work well if they were made from glass)‚ packaging (gladwrap)‚ transportation industries. Very easy to make - water bottles‚ plastic bags‚ pens‚ cups etc etc The main advantages of plastic materials are also the reason why plastic is such a problem. It lasts forever and it is very cheap to make. When I say it last forever‚ I mean it does not biodegrade. There is a flotilla of plastic the size

SAY NO TO PLASTICS By Dibakar Bose * Plastics is one of the few new chemical materials which pose environmental problem. Polyethylene‚ polyvinyl chloride‚ polyester is largely used in the manufacture of Plastics Plastics is the general common term for a wide range of synthetic or semi synthetic organic solid materials suitable for the manufacture of industrial products .Plastics are typically polymers of high molecular

Plastics are synthetic substances produced by chemical reactions. Almost all plastics are made from petroleum‚ except a few experimental resins derived from corn and other organic substances. "Plastics" derived their name from their properties to be molded‚ cast‚ extruded or processed into a variety of forms‚ including solid objects‚ films and filaments. These properties arise from their molecular structure. Plastics are polymers‚ very long chain molecules that consist of subunits (monomers) linked

IS PLASTIC BAD FOR THE ENVIRINMENT? A plastic material is any of a wide range of synthetic or semi-synthetic organic solids that are moldable. Plastics are typically organic polymers of high molecular mass‚ but they often contain other substances. They are usually synthetic‚ most commonly derived from petrochemicals‚ but many are partially natural. Whether you are aware of it or not‚ plastics play an important part in your life. Plastics’ versatility allow it to be used in everything from car

COMMON SYNTHETIC PLASTICS INRODUCTION Plastic molecules are made of long chains of repeating units called monomers. The atoms that make up a plastic’s monomers and the arrangement of the monomers within the molecule both determine many of the plastic’s properties. Plastics are one of the classification of polymers .If a polymer is shaped into hard and tough utility articles

Plastic is infinitely useful and makes life unbelievably simpler for everyone. Plastic however can have harmful effects on not only the environment but also on human health. Whether plastics advantages out way it potential health causes is the subject of debate. Plastic is used in everything from cell phones to water bottles. The fact that such a versatile and exhausted product can cause health problems should be taken into consideration. Plastic also has a harmful affect on the environment. This

Disadvantages of Plastics Disadvantages of Plastics are 1. FLAMMABLE – This is definitely an advantage in that they can be melted down‚ however soldering plastics can release toxic fumes into the environment. 2. COST OF RECYCLING – While recycling is a plus‚ recycling is a very costly endeavour. 3. VOLUME – In the United States 20% of our landfill is made up of plastics. As more products are being made of plastics‚ where will this lead us in the future? 4. DURABILITY – This is an advantage
