Question

plastic is non reactive comment on this statement

Answer 1

Plastic is a non reactive material. It is harmful to the environment. For example:- handles  of pans are made of plastic so it is clear that it has no thermal conductivity and electricians wear plastic gloves to save them from electric shock and thus it does not have good conductivity of electricity.

Plastics are polymer.  Polymers are not typically "reactive" as there are not reactive sites like metals have.
