A substance consisting at least a single organic polymer of immense molecular weight, solid in its complete form and at some form while manufacturing or processing into completed objects, can be molded by its flow is known as plastic.
A thermoses plastic solidifies or set irreversible when heated. They are valuable for permanence and robustness which are mainly used in vehicles and construction application e.g.: polyethylene, polyimide etc.
Thermoplastics were softened when susceptible to the heat and come back to the initial state at the room temperature. These can be effortlessly casted and molded into yields such as milk jugs, carpet fiber. Plastics are phenolic, melamine, unsaturated polyester etc. A thermoplastic can be easily shaped and soften when exposed to heat and return to original condition at room temperature.
What is the Need to Use Plastic?
There are numerous important properties which plastic (polymers) have that we can utilize single-handedly or combined it with other materials to make adequate or mounting input in the construction of a number of things. There are various properties of the polymers that can be stated below:
- •
They are tough and they are highly resistant to corrosion.
- •
They can be used as good insulator as they can insulate heat, cold and sound, which can save energy and reduce noise pollution up to certain extent.
- •
They are cheap to use and are long lasting.
- •
They don’t require maintenance.
- •
They can be easy to clean and they can be used to maintain hygiene.
- •
They can be easily processed and installed.
- •
In terms of weight, they are light, which makes them easy to use.
In the present world, our lifestyle designed in such a way that plastic and its applications plays an important role, which can’t be neglected. For example they are used for serving food items, protecting a number of daily items as well as defensive items for people, in throwing a huge amount of waste materials and in packaging industry. Being a non-biodegradable produce, the materials made by plastics are threat for environment, as they are responsible for polluting the environment. They are also responsible for causing breast cancer in humans, glitches in the human reproductive system as well as in animals, in addition to genital irregularities.
To surface roads, we can utilize plastic waste, such as disposable cups, plastic bags, laminated packets used for chips, plastic foils, pan masala, etc. as well as packets used to pack chocolates, biscuits, grocery items, milk and milk products. This will help in reducing plastic waste around us and they will be usefully utilized as materials to surface the roads.
Recently the studies show that plastics don’t change for around four thousand years, when disposed in our planet, Earth. Apart for it to remain non-biodegradable for several thousands of years, it was seen, that the plastics are still in great demand in case of food, medicines, etc. items which are necessary for our daily lives. All the houses are highly dependent on the use of plastics and around 5% plastic wastes are produced in the municipal solid wastes daily. This demand in plastics is keep on increasing in the cities as well as in villages, where people are using plastic bags for almost everything in their daily routine. Due to which more and more plastics are lying on the roads and pollutes the surrounding areas. This leads to raise in the world pollution levels.
