The atomizing core is an important part of vapes, and the heating device that atomizes the e-liquid together with the e-cigarette determines the taste.
In the past, the mainstream was cotton core, which had the advantage of low price and good taste; the disadvantage was that it was prone to burn e-liquid and vape juice leakage, and it relied on labor and was difficult to industrialize and control quality.
Ceramic core has been developed and promoted in the past three years. The advantages are that it does not burn e-juice, has a low leakage rate, and is industrialized and mass-produced. The disadvantage is that the price is relatively high and the taste is good enough, but the taste of the product is improved after iteration, so the penetration rate of ceramic core is increased.
Through the human body deposition model of aerosol particles, we can see that the reason why the reduction degree of the cotton core is high is because the particles after atomization are larger, between 0.7 and 0.75 microns. The large-particle mist can not only produce the rich aroma in the nasal cavity, but also deposits in the oral cavity and throat, making the oral cavity more satisfying.
The ceramic core pursues the fineness of the mist particles, and the atomized particle size is between 0.5 and 0.55 microns. The particle size of such vapor is mainly felt by the olfactory cells in the nasal cavity, so everyone feels that the reduction degree is not enough.
In recent years, ceramic atomizing core has gained the favor of the market for its advantages of “no smell and durability”. Global market experienced the natural substitution of ceramic core to cotton core, while in China, ceramic core started. At present, some China brands are willing to increase the proportion of cotton core due to cost considerations.
But after research, it is believed that cotton core and ceramic core have their own advantages and disadvantages, and they will coexist for a long time!
In reality, ceramic atomizing cores are mainly used for pod systems; cotton cores are the mainstream for disposable vapes.
For new customers, ceramic core has a lower taste reduction, but has better experience and fewer quality problems, so the acceptance is higher; for repurchase customers, ceramic core has formed a certain consumption habit.
The current atomizing core leader is also studying the possibility of other materials, but no better material has been found so far. This will be the basic reason why ceramic core and cotton core will coexist for a long time.
