property which makes the plastic mouldable?
Answers
Plastics are also called as Polymers. They are made up of carbon, hydrogen and sometimes oxygen, chlorine, nitrogen, fluorine, sulfur, phosphorus or silicon. Majority of the times, polymers are made up of Carbon, Hydrogen, and Oxygen only.
It is a low-density polymer and thereby it possesses lightweight.
It is Anti-Corrosive in nature.
It has low strength.
These chains are called polymers and that is why many plastics begin with “poly,” such as polypropylene, polyethylene, and polystyrene.
2. Properties of Plastics (11) or Polymers: Properties of plastics or polymers play a vital role in the field of Mechanical Engineering. When you want to apply any type of load on a particular member, you need to know its material properties, density, etc. For that, in this article, I am exploring the necessary properties of polymers in a detailed manner.
Properties of Plastics or Polymers:
The Properties of Polymers or plastics which are essential to know for any mechanical engineer are as follows:
Bond: It possesses a Covalent bond.
Strength: The strength of the polymer is low when compared with Metals.
Binding Energy: The formation of C, H&O atoms forms a polymer. The distance between the atoms is more when compared with metals and thereby the Binding energy is low.
Ductility: It possesses good ductility also.
Conductivity: The polymers possess bad electrical conductivity because of the absence of free electrons.
Thermal Conductivity: The polymers possess bad thermal conductivity.
Density: The polymers possess low density which means that the weight of the polymer is less and this is one of the advantages of polymers.
