Question

A plastic used for making crockery is __________

Answer 1

Hint:So to answer this question we need to remember the properties of the polymers depending on this structure. Polymers are those substances or materials which are made up of a large number of molecules or macromolecules which are made up by repeating the subunits. They have diverse properties due to which synthetic and natural polymers play an important role in everyday life.

Complete answer:
The plastic which is used for making crockery is melamine. Melamine formaldehyde or melamine or MF is tough and has high durability and ability of universal thermoset aminoplast with the good resistance of heat and fire. It is made up of condensing two monomers that are formaldehyde and melamine. It has the ability of good fireproof properties because of the release of the nitrogen gas during undergoing the process of combustion. It helps in the making of unbreakable crockery and in non stick pans too. The plastic which is used for non-stick pans or unbreakable crockery is a synthetic thermoplastic polymer of tetrafluoroethylene which has many applications. It has high resistance to heat.

Note:For crockery or utensils we use PTFE as a non sticking coat generally for pans because it tends not to react because of the carbon fluorine bond present so due to this ability it is also used in pipelines for corrosive and reactive chemicals. It is also used as a lubricant because it tends to reduce engine friction and energy consumption. It is used to coat the catheters as it affects bacteria to adhere to the catheter and causes the hospital to acquire infections.
