Hi Guys! In this article, we will learn about all different types of plastics, Their examples, and common uses in our life.
Actually, People think there are only seven types of plastics like PET, HDPE, PVC, LDPE, PP, PS & all others. But these are the examples of plastics materials according to their recycling properties. But I am going to explain the actual types and Sub-types with examples and uses.
Different Types of Plastics –
There are mainly two types of Plastics –
- Thermoset Plastics
Let’s talk more about the above types of plastics –
(A) Thermoplastics –
Thermoplastics are those plastics that can be moulded and remoulded (Recycled) many times. These plastics have their specific Properties like specific melting points, hardness, tensile strength, etc.
Now we can also classify thermoplastics into three types –
- Commodity Plastics
- Engineering Plastics
- Speciality Plastics
Commodity Plastics –
Commodity Plastics are widely used in our home applications. These Plastics are cost-effective and easy to process in the Plastic industries. HDPE, LDPE, PP, PVC, PS etc. are common examples of commodity plastics.
Engineering Plastics –
Engineering Plastics are used in application areas requiring stringent performance criteria. These Plastics replace metals and alloy in construction, transport, aerospace and electrical engineering industries. ABS, PC, Acetals, Nylons etc. are the most common examples of engineering plastics.
Speciality Plastics –
Speciality Plastics are those plastics which are having an exceptionally high value of performance properties. These are mostly used in aerospace and nuclear plant. PEEK, PES, PPO, etc. are the most common examples of speciality plastics.
(B) Thermoset plastics –
Thermoset or thermosetting plastics can be moulded only one time after that they lose their recycling properties. It is irreversibly hardened by heat.
These plastics are made by chemical reaction, Cross-linking of Liquids with the help of catalysts at specific conditions. For examples –
- Bakelite (phenolic)
- Epoxy resin
- fibre-reinforced thermoset
- Polyester resin
- Silicone resin
- Vinyl esters
- Cyanate esters
- Vulcanized rubber etc.
Thermoset plastics are also used as heat resistant in many applications. they are very hard and have ductile properties.
