Will boiling water melt plastic?

Most plastic won’t melt in boiling water. Boiling water is at 100° centigrade which isn’t hot enough to melt plastic. So if you even try then the plastic will only get hot rather than melting. But there are few plastics like polylactic acid (PLA) which will melt at around 70° centigrade.

Will boiling water crack plastic?

Is it safe to put hot water in a plastic cup? No, it is not. Hot liquid causes a potentially harmful chemical to leach out of certain plastics much faster than usual, researchers have found.


Can you pour boiling water into plastic?
