Plastics which when moulded once, cannot be softened by heating. With a number of benefits to thermosetting plastics vs. thermoplastics, the methods and materials fill an important role in the plastic fabrication industry.Within the class of thermosetting polymers, there are a number of different types of material that each serve unique purposes and applications. … Answer: Melamine is a versatile material. Revise with Concepts. Ans.Above articles are made up of bakelite (a thermosetting plastic) because it is-- (i) poor conductor of electricity (ii) heat resistant. Example of this kind of thermosetting is Melamine.b) Thermosetting plastics such as bakelite are poor conductor of heat and electricity. Explain why the following are made of thermosetting plastics. Q. Saucepan handles Answer: Thermosetting plastic is fire-resistant and can withstand very high temperature. View Answer. It is used for making saucepan handles. View Answer. (a) Saucepan handles (b) Electric plugs/switches/plug boards ... State, whether the following statements are True or False. are made of thermoplastic materials or of thermosetting plastics. Question 7: Explain why the following are made of thermosetting plastics. Electric plugs/switches/plug boards View Answer. View Answer. These are called thermosetting plastics. (a) Saucepan handles (b) Electric plugs/switches/plug boards. Electric plugs/ switches/ switch boards Dear Student Electric plugs/ switches/ plug boards are sa A thermosetting polymer, resin, or plastic, often called a thermoset, is a polymer that is irreversibly hardened by curing from a soft solid or viscous liquid prepolymer or resin. Thermosetting plastics are normally made up of lines of polymers which are highly cross-linked. Such handles do not heat up during cooking. Curing is induced by heat or suitable radiation and may be promoted by high pressure, or mixing with a catalyst.Heat is not necessarily to be applied externally. (a) Saucepan handles (b) Electric plugs/switches/plug boards. Explain why the following are made of thermosetting plastics. Due to this, saucepan handles are made of thermosetting plastic. The heavily cross-linked structure produced by chemical bonds in thermoset materials is directly responsible for the high mechanical and physical strength compared with thermoplastics or elastomers. Explain why the following are made of thermosetting plastics. VIEW MORE. Thermosetting Plastic - Thermosetting plastics are made up of long lines of molecules that are cross-linked. Heat provides energy for chemical reactions that increase the cross-linking View Answer. The bakelite is a thermosetting plastic. A thermosetting plastic is a polymer that irreversibly becomes rigid when heated. View Answer. Understand the Key Differences Between Thermoplastic and Thermosetting Plastic with detailed explanations and examples. Such a material is also known as a thermoset or thermosetting polymer. a) Saucepan handles are made of thermosetting plastics because it resist fire and tolerate heat better than other plastics. It resists fire and can tolerate heat better than other plastics. Initially, the polymer is a liquid or soft solid. 8. Explain why thermoplastics are easier to recycle than thermosets.
