What temperature will ignite cardboard?
Flashpoint and “ignition temperature” and “combustion temperature” are, for all intents and purposes, the same thing, and thus – the flashpoint of cardboard is 800 degrees Fahrenheit.
Can cardboard ignite from heat?
Cardboard is combustible, so it can easily catch fire when heated at high temperatures for extended periods.
At what temperature will paper ignite?

Is cardboard a good insulator?
As regards to its insulation properties, cardboard is actually a great insulator as it has poor thermal conductivity. The definition of conductivity is actually the property of a material to transmit energy. The porous composition of cardboard is the reason that makes it an excellent sound-proof material.
Can wet cardboard spontaneously combust?
Carbon-based animal or vegetable oils, such as linseed oil, cooking oil, cottonseed oil, corn oil, soybean oil, lard and margarine, can undergo spontaneous combustion when in contact with rags, cardboard, paper or other combustibles.

Oven-safe parchment paper may darken a bit in the oven, but it won’t catch fire.
What temperature do things catch on fire?
