FriXion pens are not technicallyerasable.Friction makes the ink invisible, but it's still onthe page.FriXion Gel Pens: Friction causes heat–>heat makes the ink turn clear –> ink is stillon the page,you just can't see it.
Likewise, people ask, what makes erasable pens erase?
Erasable pens work in two ways, rubber cementandthermo-sensitive ink. In newer erasablepens,“thermochromic ink” is used as the pigment. Bydefault,this ink is dark but when the ink is heated up, such asfrom thefriction of an eraser, it turns clear to make itseem as ifthe ink was erased.
In respect to this, how does the frixion erasable pen work?
Erasable pen uses heat to make thewritingdisappear Frixion pens are not the smearinghorrorpens that you may have used in school — the inkis notrubbed away — it actually becomes invisible when heatedwithan erasing motion of the rubber tailcap. No eraser dustisgenerated.
Erasers have a rubbery consistency and come inavariety of shapes, sizes and colours. Some pencils haveaneraser on one end. Less expensive erasersaremade from synthetic rubber and synthetic soy-based gum,butmore expensive or specialized erasers are vinyl, plastic,orgum-like materials.
