Synthetic Fibre of Class 8
Plastics are polymers of long carbon chains. Plastics that get deformed easily on heating and can be bent easily are known as thermoplastics. PVC polythene, nylon, acrylic, celluloid and cellulose acetate are examples of thermoplastic.
Plastic which on molding doesn’t get soft by heating are called thermosetting plastics. Bakelite, melamine, vulcanized rubber, duro-plast and epoxy resin are examples of thermosetting plastics
