Hard rubber, also known as ebonite, is a type of rubber that has been vulcanized to achieve increased hardness and durability. It is commonly used in applications requiring electrical insulation, such as in electrical components, as well as in products like combs and Musical Instruments. The material is characterized by its dark color, resistance to chemicals, and ability to maintain shape under stress. Hard rubber is less flexible than standard rubber, making it suitable for specific industrial and consumer uses.
What else can I help you with?
Is rubber strong?
rubber is not strong on its own but when it is vulcanised,i.e.,heated with sulphur to a definite temperaturefor a known period of time,it becomes strong because sulphur atoms act as bridges between rubber molecules, initiate cross-linking and convert the soft sticky rubber into a hard, elastic mass which can be put to extensive uses such as use in tyres,etc Because it is elastic.

What is rubber tires made of?
Because, rubber is a specific type of polymer called an elastomer: a large molecule that can be stretched to at least twice its original length and returned to its original shape. Early forms of rubber had many gluelike properties , especially in hot weather. In cold temperatures, rubber became hard and brittle. It was only after an accidental discovery b y Charles Goodyear in 1839 that modern rubber became possible.Since that time, rubber has become an important natural polymer in society. We make rubber from rubber trees (natural latex) and from oil (synthetic rubber). We use both types of rubber in many products. Like the Mesoamericans (Aztecs and Mayans) before them, athletes and children today play with rubber balls. Of course, the most common use for rubber is in automotive tires. But pencil erasers, shoes, gloves, dental dams and condoms contain the ubiquitous substance, too. In many products, rubber is added as a protective coating for either weatherproofing or shockproofing.Ravinder Dahiya (Mechanical Er.)
Tire is soft rubber or hard rubber?
They are made both soft and hard, depending on application.
Which is the best material for insulating wires in a circuit hard rubber lead silver or tungsten?
Hard rubber
If you rub hard rubber with piece of wool what charge is on the piece of rubber?
The hard rubber would acquire a negative charge as electrons move from the wool to the rubber. Wool has a higher tendency to lose electrons, leaving the rubber with an excess of electrons and thus a negative charge.
Is rubber more brittle than glass?
no because rubber is hard as :-- and glass cannot
Is a rubber or hard case better for a Pantech matrix?
Rubber cases because when they fall to the ground they bounce. Hard cases just crack the screen.
Why car is not made of hard rubber so that it is more elastic during collision?
Actually, hard rubber is not elastic. If you have ever had a hard rubber ball you know this. Also, rubber dries out and cracks in hot weather and doesn't expand or contract in cold weather so it would just fall apart eventually. Most people want to keep a car going for several years and it wouldn't hold up if it was hard rubber. Hard rubber is used in cars for hoses, tires, and other things, but to have the car made of it just is not practical.
