Question

Which plastic is called a fire proof plastic?
A.Melamine
B.Bakelite
C.Teflon
D.Acrylic

Answer 1

Hint: Fire proof plastic or Flame-retardant plastic additives are compounds added to plastics or other materials to inhibit, vanquish and delay combustion. These compounds are useful in looming burning in the ignition phase of fire. They neither stop charring or melting nor do they increase the heat resistance of a material.

Complete step by step answer:
Flame retardants such as aluminium, phosphorus, magnesium, chlorine, sulphur, nitrogen and bromine are implied by many different mechanisms that include preventing a material from catching fire, slowing or extinguishing the fire and protecting materials from heat.
Melamine is a plastic that can tolerate heat better than other plastics and resist fire too. It is used for making floor tiles, ashtray, fire resistant fabric and unbreakable kitchenware. Certain plastic cookware made of melamine is used in microwave ovens for cooking food.
Bakelite is a hard and tough plastic which is used for making the handles of various cooking utensils (fry pans, pressure cooker). Like Melamine, it is a poor conductor of heat and electricity too.
Teflon is an exceptional plastic on which oil and water do not stick because it has a slippery surface. It can resist high temperatures and is used for making soles of electric irons, providing non-stick coating on cookware.
Acrylic fibres are synthetic fibres made from polymers. It is used for many different applications that usually take advantage of its original transparency and the impact resistance of certain variants.

Therefore, the correct answer is option (A).

Note: Melamine is poor conductor of heat and resists fire. Many of the synthetic fibres are poor conductors of heat and electricity. Therefore, melamine is used as a coating on the uniforms of firemen because they are flame resistant.
