What is Ebonite?
Ebonite is a type of resin that has a very long history. It is considered the first “synthetic resin” to become widely used.
In 1839, ebonite was invented by Mr. Charles Goodyear in the United States.
Ebonite is blackish brown and firm, but its main raw material is rubber. By mixing and heating rubber and sulfur, they combine and become low-elastic and very firm vulcanized rubber with an elongation percentage of approximately 3%.
This is what ebonite is.
The name “ebonite” comes from the meaning “ebony.”
Ebonite is black-colored, elastic horn-like material, and a crack in ebonite is glossy. It is clear brownish-red in thin-film form and brownish-red in powdered form.
Ebonite is sometimes called “hard rubber.” But we distinguish with hard rubber that is hardened with fillers.
Ebonite is durable, scientifically stable and provides excellent electrical insulation and machinability. Before the rise of petroleum-derived plastic, ebonite was widely used in every aspect of life.
When the surface of ebonite is polished, it gives a beautiful, lacquer-like gloss.
Also, with a characteristic that does not disturb tones, it is used as inner pipes of woodwind instruments.
With these characteristics, ebonite is widely used in many ways, including electrical insulation materials, premium gold or silver lacquer fountain pens, instrument mouthpieces, smoking supplies and fishing gear.
Our company uses 100% high grade natural rubber collected from gum trees. A gum tree is one of the trees that has a high absorption rate of carbon dioxide. We will continue to commit ourselves to manufacturing ebonite products utilizing natural rubber.
