Consider the following statements regarding applications of polymers: 1. Kevlar is used in the manufacture of bullet-resistant jackets and helmets due to its high strength. 2. Polytetrafluoroethylene (PTFE) is widely used as a non-stick coating in cookware because of its low friction and chemical inertness. 3. Bakelite is a thermoplastic polymer commonly used for making disposable plastic bottles. Which of the statements given above are correct? |ForumIAS
