Hard rubber parts commercially known as ebonite are manufactured by vulcanizing from a specific compounding technique. The hardness of ebonite rubber parts is measured in the Shore D scale.
KPM produces black ebonites, coloured ebonites and marbeled ebonites in different polymers against its applications.KPM can supply the ebonites also known as hard rubber washers, after machining, as precise as customer drawing.
Different chemistry is used for ebonite / hard rubber manufacturing, they combine and turn out to be less flexible and with a poor elongation percentage close to zero. Hard Rubber provides excellent electrical insulation performance, durable and good machinability.
