Melamine is a thermosetting plastic which is resistant to fire and can tolerate heat better than other plastics. Thermosetting plastics or Thermoset plastic are synthetic materials that strengthen during being heated but cannot be successfully remolded or reheated after their initial heat-forming called as Thermoset material. They have a very rigid structure. The terms thermoplastic and thermoset stand for how a material is or can be processed under a changed temperature [1]. Thermoset plastics are frequently used for sealed products due to their resistance to deformation and are also among some of the most impact resistant plastics available. Thermosetting plastics are often formed by condensation polymerization. Bakelite is a thermosetting plastic which is a poor conductor of heat and electricity. Heat capacity of air can be approximately expressed as, Cp = 26.693 7.365 x10-3 T, where, Cp is in J/mole.K and T is in K. The heat given off by 1 mole of air when cooled at atmospheric pressure from 500°C to - 100°C is Thermoplastic & Thermosetting plastic – A Summary. Correct answer is (a) Melamine Thermosetting : Thermoplastics are usually formed by the addition of polymerization. Planck\'s distribution law is valid for _____ bodies. A thermosetting plastic is a polymer that irreversibly becomes rigid when heated. Polyethylene or polythene is the most common plastic in use today. They tend to char and burn when heated, but they are resistant to much higher temperatures than thermosoftening plastics. It is a useful plastic for molding and extruding in various shapes such as bottle, sheets and pipes etc. Thermoplastic and thermosetting plastics come in a wide range of material options and can serve a variety of applications as long as the material limitations cannot cause product failure under the intended operating conditions. Thermoset plastics do not - for instance Thermosetting plastics do not— remould— on heating. Thicker plastic material is often called a "sheet". Examples of thermoplastics include polythene (PE), polypropylene (PP), polyvinyl chloride (PVC), polystyrene (PS), nylons, etc. There are many different kinds of polyethylene, usually called polythene, and abbreviated to PE.
