define thermoplastic and thermosets plastic with example
Answers
Answer:
Thermoplastic polymers are linear (slightly branched) long chain polymers, which can be repeatedly softened and hardened on heating. Hence, they can be modified again and again.
Examples include polythene, polystyrene.
Thermosetting polymers are cross-linked or heavily branched polymers which get hardened during the molding process. These plastics cannot be softened again on heating.
Examples of thermosetting plastics include bakelite, urea-formaldehyde resins.
Answer:
Thermoplastic:
These are the plastics which get deformed easily on heating and can be bent easily.
Examples:
PVC and Polythene are used for manufacturing combs, toys, car grills and various type of containers.
Thermosetting plastic:
These are the plastics which when molded once, cannot be softed by heating.
examples:
Bakelite and Melamine. Bakelite is a poor conductor of heat and light. Bakelites are used for making electrical switches, handles of various utensils etc.
Melamine is resistant to fire and can tolerate heat better than other plastics. Melamines are used for making floor tiles, kitchen wares and fabrics.
