How It's Made Plastic Moulds

Discover The Making Of Plastic

What is common between laptop computer bags, hair loss products, skin care treatment bottles? It is Plastic. Plastic comes from petroleum. The petroleum is drilled and taken to the refinery. Here crude oil is refined into natural gas, grease, wax, kerosene, petrol, ethane, butane, propane, naphthalene, tar and many other such products.

The propane and ethane are cracked into propylene and ethylene at about 3000 degrees centigrade. A catalyst is combined in propylene and ethylene making what is known as fluff which is a powdery material which looks like washing detergent. The fluff is put into a blender other additives are added to it continuously. Now becomes a polymer where it is fed into an extruder and melted.

This molten plastic is cooled and pelletized in a pelletizer. These plastic pellets are then offered to customers who buy it to make various products. These customers then get these pellets molten and moulded into their requirements by processes like blowing, extrusion and injection. As it has invaded all requirements of life that is way it is considered as the greatest innovation of the 20th century.

Some desirable properties is its lightweight, does not rot rust, as it is light more bottles or packets can be transported thereby reducing transportation cost. It is believe the save natural resources, because sand to make glass is not removed off the beaches which is a home to many intertidal species endemic to the seashores only. Trees to make paper and cartons are saved, too.

Even though there are so many benefits, why is the use of plastics banned in certain places? This is because after industrial and domestic sewage plastic is the third most dangerous pollutant. It is non-biodegradable, remains in the ecosystem for 700 years, and is highly toxic.

There is no way to dispose plastic waste in a safe manner and it also causes damage to the environment at its production and disposal. Therefore the only way to deal with plastic is to reduce its production and wean ourselves of our dependence in it.

Right from its production to its disposal plastic is a threat to the environment and there is no safe way to deal with it. At present the only way to deal with this menace is to decrease its production and ban it. The other way is to engineer a bacterium which feeds on plastic like the once we use in dissolving oil-slicks. Hopefully these are reasons enough to avoid plastics?
