Depends upon what you wish to insulate against. Heat loss, high temperatures, electrical, ... .
For electrical, plastics and rubber are common.
For heat loss, foam polystyrene, or cotton cloth.
For high temperatures, your choices are limited, for organic materials don't perform well here.
These are impurities as organic compounds in different materials.
inorganic materials is non-biological materials. they are formed due to natural growth.
Materials made by living things
amorphous solids
In the sentence, "Sinking below the lighted surface, waters are organic materials", the subject is waters. You can easily find the sentence subject by exchanging the two halves of the sentence, then editing out any extraneous words and changing words to fit the new sentence..So for examples:Waters are organic materials below the lit surface.Waters contain organic materials below the lit surface.
A major feature in many insulating materials is TRAPPED AIR.

Insulating materials tend to be friable - able to be crumbled to dust by hand pressure alone. You do not want dust from such materials falling into open incisions. In addition, insulating material sent do be porous and thus difficult or impossible to clean to the level of disinfection required by an operating room.
For insulating a current you can use plastic/rubber.
Copper rod is covered by insulating materials, because copper is good conductor of electricity when we touch copper rod we get shock and insulators are bad conductor of electricity hence copper rod is covered by insulating materials
electrician tools must be insulated so that they dont get electrocuted
human body is good conductor of electricity.For our safety electric tool are coated with insulating materials.
Only materials or artefacts containing organic materials can be used.
