Changes With Time Go For Polymer

As the time is advancing, the new inventions are heading towards us. These days, the polymers are used in the market on the wide range. Polymers are nothing but a macro molecule, having very high molecular weight. These are made up of single unit, i.e. monomer repeating several times and forming a polymer. The polypropylene is also a polymer having several units of propylene monomers. These days, polypropylene is used in the packaging industries. Not only this, the polyethylene is also widely used for the same. Polypropylene is another polymer which is made up several units of ethylene. The two polymers are different from each other in several aspects likes molecular weight, size, properties and many more. On the basis of all this, there uses are set up and then used further. Polypropylene packaging is widely used and so widely used just because of the polypropylene great and immense properties which cannot be seen anywhere else. It is very light in weight, having high tensile strength or in other words it is very strong, it acts as an insulator and also corrosion free. This shows that it remain unaffected by the outside atmospheric effects and keeps the packed material safe and steady. It can deal nicely with any jerk or force over it, and can keep the inside material as it is. Not only this, it is flexible and can be easily molded in to any shape. It is non toxic and environmental friendly. In case of polyethylene packaging, the two types' of polyethylene are available, low density polyethylene and high density polyethylene. The one with the controlled molecular structure leads to LDPE i.e. Low density polyethylene and the one with the uncontrolled molecular structure leads to HDPE i.e. High Density Polyethylene. It is also flexible, with high tensile strength, strong, and very light in weight. Along with that, it is very inexpensive. It is available in very low cost and so its popularity has raised al lot in short time. These are very few of its properties that are mentioned here. The polypropylene packaging and polyethylene packaging is nowadays used almost in everywhere in the world. Either it is, America, London, Germany, or India, every developed country wants to move further with the time and so going for the new activities which proves to be very useful. All such innovative steps are for the betterment of the society and this planet earth.
