All plastics are polymers (but not the other way around). There are a zillion different plastics, and a wide range of melting temperatures for them. Some don't melt, but actually suffer decomposition at higher temperatures because their molecular structure won't permit them to melt. Unfortunately, the question is so broad that not much more can be said except to give some examples of common plastics:

  • PVC, polyvinyl chloride, melts at 212 °C (about 414 °F)
  • Teflon®, which we use to coat cookware, is polytetrafluoroethene - PTFE, and it melts at 327 °C (about 621 °F)
  • POM copolymer has a melting point of 162-173 °C.
  • PLA softens at 50 °C
  • ABS softens at 90 °C

It depends on the plastic.

Low-density polyethylene melts at 105 degrees C - just over the temperature of boiling water.


At the other end of the scale is a very large category of plastics called "thermosetting." Epoxy, polyester resin, melamine and silicone are thermosetting. Thermosetting plastics don't melt.

There are thousands of kinds of "plastic" . ( polystyrene, polyvinyl, plexiglass, lucite, polyvinylchloride, ABS, CPVC, etc, etc , ) -All melt at different temperatures. -You will have to specify an exact type for an answer.

There are different types of plastics and the melting point is also different. Refer to the link below for melting point and other data.

it needs to be over 101c. At school we did science at that was what we needed to do so i know. It needs to be really hot but if you do it do not burn yourself but nobody try this at home.
