Do mesh heating elements alter the molecular structure of the liquid?
No, mesh coils do not change the molecular structure of your e-liquid; they simply optimize its physical change of state through an increased heating surface area. Unlike traditional wires, mesh acts like a fine grid that distributes heat very evenly, preventing the "hot spots" responsible for the premature degradation of flavor molecules.
This technology allows for more efficient vaporization at stable temperatures, thereby preserving the chemical integrity of propylene glycol and vegetable glycerin without triggering unwanted reactions. The result is denser vapor and truer flavors, as the liquid is "boiled" more gently over a wider area. In short, mesh improves the physics of vaping without turning the chemistry upside down.
