In this article, I will be explaining the different types of Plastics used in our household applications as well as industrial applications in the form of Thermoplastics and Thermosetting Plastics with there Properties.
but before that let we know what is a Plastic?
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.
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.
The Properties of Polymers or plastics which are essential to know for any mechanical engineer are as follows:
It possesses a Covalent bond.
The strength of the polymer is low when compared with Metals.
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.
It possesses good ductility also.
The polymers possess bad electrical conductivity because of the absence of free electrons.
The polymers possess bad thermal conductivity.
The polymers possess low density which means that the weight of the polymer is less and this is one of the advantages of polymers.
The polymers are Anti-Corrosive to the environment.
The servicing temperature of the polymer is 300̊ C.
It is hazardous and is not environmental friendly.
The polymers are recyclable in nature.
These are the 11 properties of polymers or plastics which are discussed in a detailed manner. Hope you had got an idea of what plastic is? Now, let's discuss the Classification or Types of Plastics.
They are two types of Plastics:
By heating the polymer, if it turns soft, then it is called as Thermoplastic material. At room temperature, they are available in the form as Solids.
A thermoplastic is a plastic material that becomes moldable above a specific temperature and solidifies upon cooling.
In this article, I will be explaining the top 10 properties of thermoplastic materials in a detailed manner.
The Properties of Thermoplastic material are as follows.
The examples of Thermoplastics are as follows.
By heating the polymer, if it turns hard, then it is called as Thermosetting plastic material. At room temperature, they are available in the form as liquids.
Thermosetting plastics or Thermoset plastic are synthetic materials that strengthen during being heated but cannot be successfully remolded or reheated after their initial heat-forming called as Thermoset material.
The Properties of Thermosetting Plastic material are as follows.
The examples of Thermosetting plastics are as follows.
So this is all about types of plastics with their corresponding properties. I hope you liked this paper if so don't forget to share this stuff with your friends, and if you have any doubt do not hesitate to comment down below.
The two main types of plastics are Thermoplastics and Thermosetting Plastics.
The seven types of plastics are Polyethylene Terephthalate (PET or PETE or Polyester), High-Density Polyethylene (HDPE), Polyvinyl Chloride (PVC), Low-Density Polyethylene (LDPE), Polypropylene (PP), Polystyrene, etc.
Examples of thermoplastic are Polyethylene, Poly Vinyl Chloride(PVC), and Teflon.
Examples of thermosetting plastic are Epoxy, Silicone, Polyurethane
The properties of thermoplastic polymer are ductility, thermal conductivity, bond, strength etc.
The properties of plastic are low strength, lightweight and Anti-Corrosive in nature.
