Kurashiki Kako's technology

Our position is that compounding, production and evaluation of rubber materials are our important technologies.
Elastic rubber materials are produced by compounding and kneading polymers such as natural rubber and different types of compounding agents, and then through chemical reactions of such kneaded polymers at a desired temperature and for a desired time.
This chemical reaction is called vulcanization in which natural rubber which tends to cause plastic strain is changed to more elastic rubber materials.

Compounding technology

Fully utilizing the advantages of compounding agents, Kurashiki Kako provides rubber materials which enable high level anti-vibration ability, heat-resistance and endurance required in the automotive industry for anti-vibration rubber mounts and hoses.
The compounding technology gained through the production of automotive rubber components is utilized in general industrial instruments so as to suggest different types of anti-vibration devices to our customers.

Production technology

Compounding and kneading technologies, vulcanization and forming technologies, and in the case of components combined with metal parts, bonding technologies are important production technologies for rubber materials.
Compounding and kneading technologies homogenize rubber materials to contribute to the improvement of durability and mechanical strength.
Vulcanization technology contributes to the improvement of productivity through the realization of complex shapes and speeding up of the vulcanization process reaction.
Bonding technology is used to combine heterogeneous materials, such as metal and rubber. The requirement of strength of complex bodies, in general, is breakage of base materials but no spalling at the interface during the bonding test.

Evaluation Technology

These are the analyses technologies for materials, including physical property evaluation technology, environment resistance evaluation technology and qualitative and quantitative material analysis technology.
These are used to evaluate quality performance, such as material processing, vulcanization reaction and mechanical property, and clarification of the mechanism of complex rubber degradation caused by contact with chemical substances and repeated deforming.
