The Science Behind FriXion Erasable Pens (pilot frixion pen review)

Made for parents and teachers The Science Behind Erasable Ink I did 5 different experiments (2) with the microwave, hair dryer, plastic friction and Freezer. Yeah a Freezer, wait I said HEAT Erasable ink, well turns out you can reverse the process if you put it in the freezer. How cool is that. Let me know if you have other ways you have tried. Now I only used Black, but FriXion has many different colors.

One component is a pigment (the color) that reacts to acidity by turning invisible. The second component is a chemical that acts as an acid or a base. The third component reacts to heat by activating the acid/base. By twiddling these three components, the manufacturers can make an ink that disappears when enough heat is applied and reappears when sufficiently cold. When you erase with the rubber, the friction creates heat which changes the acidity of the ink and makes it invisible. When it is cooled down, the acidity changes back and the ink becomes visible again. Many years of development went into the thermosensitive Metamo ink that gives the FriXion line its main selling point. Microcapsules that form the pigmentation contain an equal mix of three substances. These 3 parts, A B & C is how it works. (A) Color Pigment, (B) Color-Activating Agent and (C) Transparency Agent. At regular temperatures Color Pigment (A) and Color-Activating Agent (B) are bound together. Allowing the color to show. When the ink is rubbed with a hard-plastic eraser heat from the resulting fiction causes (B) to separate from (A) and bind with Transparency Agent (C). (A) becomes ineffective and the ink color disappears from the page. the science behind frixion erasable pens pen review
