is plastic a heat insulator or heat conductor?

i don't know this but i think plastic is a very good heat insulator

Plastic is a very good thermal insulator

For the best answers, search on this site https://shorturl.im/axSOx I don't think heat conductivity has anything to do with color. Metals are good heat conductors while wood and plastics are poor heat conductors. Black rough objects get hotter in the Sunlight than white shiny ones because they do not reflect sunlight as efficiently.

You are actually correct, plastic is a perfect heat insulator rather than heat conductor.Metals are the conductors

Is Plastic An Insulator

plastic takes in a rather broad spectrum. It is a medium to poor conductor of heat. plastic that has closed cell air bubbles like a coffee cup acts as an excellent insulator, however it is the air pockets that make it effective. Plastics can be used on cookware to give an insulated handle. Epoxy compounds can join materials that need thermal conduction, especially if the epoxy is doped with metal plastic is blind to radiation, so it allows ice to form quickly when the tray is put in the freezer as heat radiates out of the water. far superior in function to aluminum trays even though aluminum is a better conductor of heat.
