It is the Fourier heat transfer equation.

Minus a good margin to keep things from ever approaching the flash point
of paper... at the very least. It is actually held to a temperature
even lower than that. The flash point (or melting point_ of PVC is
likely lower than that of paper. Why PVC is still in use is beyond me.

PVC starts to get gooey at about 450F[1]. It's still in use because it's
cheap, (relatively) easy to extrude, and it works.

Cheers!
