Synthetic polymers and resins serve specialized functions in household items and engineering materials due to their distinct thermal and mechanical properties. Match each polymer listed in List I with its primary daily life or industrial application in List II:
- Teflon (Polytetrafluoroethylene)Non-stick surface coating for culinary cookware and chemical seals
- Bakelite (Phenol-Formaldehyde Resin)Molding of electrical switches, plugs, and heat-resistant saucepan handles
- Melamine (Melamine-Formaldehyde Resin)Manufacture of shatter-resistant dinnerware and unbreakable crockery
- Kevlar (Poly-para-phenylene terephthalamide)Fabrication of bulletproof vests and lightweight high-tensile armor
Answer
Teflon matches with non-stick cookware coatings; Bakelite matches with electrical switches and heat-resistant handles; Melamine matches with shatter-resistant dinnerware; Kevlar matches with bulletproof protective gear.
Teflon is chemically inert and non-adhesive, making it the premier coating for non-stick cookware. Bakelite is an electrical insulator and heat-resistant thermoset suited for switches and cookware handles. Melamine provides a hard, glossy, shatter-proof finish ideal for dinnerware. Kevlar possesses ultra-high tensile strength essential for ballistic armor.
