Erasers were originally named "rubbers" the reason being the tree resin they were made of "rubbed out'' pencil marks.
The eraser is still known as a "rubber" in Great Britain.
More and more of today's erasers are made from something other than rubber!
Many erasers produced today are made from a synthetic rubber compound or from vinyl, which is a type of durable, flexible plastic.
Several synthetic rubber compounds have been used to make erasers.
These include isoprene-isobutylene (butyl rubber), styrene-butadiene, and ethylene-propylene copolymers.
Synthetic rubber began to replace natural rubber in erasers by the 1960s. Since the mid-1990s, erasers have been made nearly exclusively with synthetic rubber, primarily polyvinyl chloride. The driving force to complete the changeover was to help prevent allergic reactions to latex, mainly in schoolchildren.
There are many types of erasers, including handheld flat rectangles, cylindrical plugs attached to a pencil, or caps that fit over the end of a pencil. There are also all sorts of colourful novelty erasers in various geometric shapes with holiday, animal, sports, and other motifs.
