What Causes Plastic Tanks To Melt Or Crack?
Many users of electronic cigarettes that have plastic components like tanks for e-liquid have been experiencing cases of the tanks melting or developing cracks. This has led to a lot speculation as to what could be responsible for that occurrence.
The naysayers have even jumped onto this as one of the reasons that “prove” how dangerous electronic cigarettes are. These prohibitionists have gone on to say that there are very toxic agents in electronic cigarettes and it is these agents that are causing the plastic to melt. If it can melt plastic, they say, imagine what it is doing to your tender lungs and heart tissue!
As usual, these scaremongers are engaging in what they have been doing for a very long time that is, not bothering to understand something but instead clutching at straws in order to suit their agenda of demonizing electronic cigarettes.
They fail to realize that there is a simple chemical process taking place and that is what is causing the e-liquid tanks to melt or crack.
The cause is not some sinister content in the electronic liquid. The cause is the incompatibility between the poly-carbonates in the plastic and the esters, keytones and acids in some e-liquids.
As an example, get organic oranges that are fresh and make juice out of them and then assemble several plastic containers into which you put this organic juice. After several hours, you will notice that at least one of those containers will have either cracked, fogged up, softened or even melted.
Would the cause of what you see be the orange juice? If it was just the juice, then all containers would exhibit the same outcome. The fact that some containers and not others show this wear is testament to the fact that the composition of the affected container is not compatible with the citric acid in the organic orange juice. It would therefore be insane to say the juice is so toxic that not even plastic can withstand its “fire”.
Issues of compatibility are everywhere and that is why not every container can be put into a microwave oven and each electronic device has a battery that is made just for it. It is normal for incompatible items to affect one another!
So, as for the melting tanks, the cause is not harmful agents in the e-liquid. The cause is a matter of citric acid (from the fruit flavours), malic acids found in sour flavoured e-juice and cinnamon. These elements will crack plastic.
Manufacturers of e-cigs have taken note of this anomaly and have started making tanks from a better form of material like pyrex glass which is not affected by these natural chemicals in the flavours used in e-liquids.
It is therefore important that all users of electronic cigarettes understand why their tank is cracking so that once they are equipped with this knowledge they can ask for an e-cig that will not succumb to this problem once they use it. They can also educate the alarmists out there.
