Hard Rubber Parts Applications, Properties, & Manufacturing

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.

When resistance is the only required property, Hard rubber parts can serve the need beyond expectations. Hard rubber parts commercially known as ebonite are used. The inertness of the vulcanised rubber literally resists to many oxidative chemicals and other conditions. Considering the fact that the service life of the hard rubber parts is remarkable, they are too hard to be replaced.

They are manufactured by vulcanizing from a specific and a laborious compounding technique. With an inhouse testing facility of the Shore D scale and expertise in the same, we can certify the hard rubber products as well.
KPM can supply the ebonites also known as hard rubber washers, after machining, as precise as customer’s prints. The structure of the part and the criticality is as per customer’s prints as well as the properties. With an experienced team of chemists and the skilled technicians, KPM formulates the hard rubber parts as per specification against application environments. KPM has the facility and the techniques to produce

Black ebonites
Coloured ebonites
Marbeled ebonites

Custom molded hard rubber parts in different desired polymers against its applications.

A diligent chemical practice is required to mold the 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. Having a rich history hard rubber parts find their application in meticulous parts like musical instruments, batteries, cosmetics, sports products as well as research parts in physics. Due to their chemical property of resisting the foreign media they are used in lining in tanks and vessels.
