Explain thermo plastics and Thermosetting plastics with examples ans
Answers
Answer:
Plastics which can be easily deformed and bend easily on heating are known as thermoplastics. Plastics once moulded cannot be bent or deformed are known as thermosetting plastics. They are used for making toys, containers. They are used for making switches, handles of utensils, Examples are PVC, Polythene.
What is Thermosetting Plastics?
Thermosetting plastics are made up from long chains of molecules that are cross-linked. They have a very rigid structure.
Once heated, thermosetting plastics can be moulded, shaped and pressed into shapes. Once set they cannot be reheated since they are permanently set.
Thermosetting Plastics
When you are studying polymers in chemistry you will generally come across a typical question like “distinguish between or write the differences between thermoplastic and thermosetting plastic.” While thermoset plastics and thermoplastics sound very similar, they are totally different compounds and have different properties as well as applications.
Basically, thermosetting and thermoplastics are two different types of polymers and they are mostly separated based on their molecular bond and reaction to heat.
Difference Between Thermoplastic and Thermosetting Plastic
Talking about the differences between thermoplastic and thermosetting plastic, well the main distinguishing factor between the two is that, thermoplastic materials typically have low melting points due to which they can further be remoulded or recycled easily.
Some examples of thermoplastics are listed below.
Polystyrene
- Teflon
- Acrylic
- Nylon
Examples of thermosetting polymers include:
- Vulcanized rubber
- Bakelite
- Polyurethane
- Epoxy resin
- Vinyl ester resin
