Look like we have new myth that everyone can try on their own, RM1 polymer melted under the sun? Hahahaha.... I am not sure if those guys are joking or they're plain stupid. A political page in Facebook is sharing a group of photo's showing a melt new RM1 Polymer note. They claim that the note is melted under a sun in a car and many people also believe it without doing their own experiment. Just get a piece of the new RM1 or RM5 polymer notes and try put that notes in your car for a week, a simple experiment that you can do it yourself before you're condemning your own money. Why I am laughing? Because I several time has been leaving my polymer in my car few time before and this kind of thing never happened to me. Unless you left the notes on your engine while driving. Hahahahaha....
In my opinion, this is just a way for people to complain about Malaysia government, it is just a political thing. Malaysia Polymer notes has been tested under hot temperatures (over 100 degrees Celsius, BNM claim it can stand up to 120 degrees Celsius) and cold temperatures under 60 degrees Celsius. That is a standard quality procedure for any Polymer banknotes for their durability. How hot it is normally in Malaysia? 37 degrees Celsius? Consider the heat is double in your car and you only get around 74 degrees Celsius, right? That heat not enough to melt your money. Still don't believe me? Let's do some experiment with the new notes. You can try put that notes in your car for a week or you can try put it in a hot boiling water (not boiling it in water) for over an hour. What is the result? Your banknote will still retained their shape and size. I think a boiling water test already enough to proof that the claim of the RM1 polymer melted under a sun is just a bogus claim.
However, you need to understand that polymer notes like any other notes cannot stand extreme conditions, they're made for normal circulation. Your currency are suppose to be put in your pocket or in a bank not in your car. If your notes a damaged because of high heat, you can always go to any Bank Negara Malaysia (BNM) branches to change the notes. Just make sure you're not intentionally damaged the notes, you might don't get the full value of your notes.
