Question

Different polymers and their properties

Answer 1

Some of the useful properties of various engineering polymers are high strength or modulus to weight ratios (light weight but comparatively stiff and strong), toughness, resilience, resistance to corrosion, lack of conductivity (heat and electrical), color, transparency, processing, and low cost.

Answer 2

On the basis of the type of the backbone chain polymers can be divided into 2:

Organic Polymers: Polymers with a carbon backbone.

Inorganic Polymers: Polymers with a backbone constituted by elements other than carbon.

Polymers on the basis of how they are synthesized can be divided into two:

Natural Polymers: Polymers that occur naturally.

Synthetic Polymers: Polymers made by man.

Few of the important polymers out there are :

Polypropylene: It is a type of polymer that softens beyond a specific temperature allowing it to be molded and on cooling it solidifies. Due to its ability to be easily molded into various shapes, it has a lot of applications. A few of which are in stationary equipment’s, automotive components, reusable containers speakers and much more. Due to its relatively low energy surface, the polymer is fused with welding process and not using glue.

Polyethylene: It is the most common type of plastic found around us. Mostly used in packaging from plastic bags to plastic bottles. There are different types of polyethylene but their common formula being (C2H4)n.
