Before these techniques were employed, plastic automobile parts would often crack when exposed to cold temperatures. Explain the difference between thermoplastic and thermosetting plastics. Join now. The material difference between the two is that thermoplastics can be remelted , while thermoset plastics remain in a permanent solid state once hardened . The uses of thermoplastics are mentioned in the chapter, Synthetic Fibres and Plastics. Three main advantages of using plastic containers for storing food are: They do not react with food items. Thermoplastic polymers melt on high temperature and on cooling they again convert into solid form. Telephone instruments, plastic toys, cooker handles, carry bags, ball point pens, plastics bowls, plastics covering on electrical wires, plastics chairs, and electrical switches. They don’t corrode. Log in. The classification is based on the chemical structure. Depending on the resin, thermoplastics can serve low-stress applications such as plastic bags or high-stress mechanical parts. Today I am telling about types of plastic. Ans. These possess intermolecular forces of attraction intermediate between elastomers and fibres.
