Material engineering

Contributing to weight-reduction and silence through the use of sponge rubber.

There are a variety of types of rubber material. We make our products from EPDM (ethylene-propylene rubber). In particular, sponge rubber has air bubbles inside and our core technique for producing the material is the use of chemical foaming agent etc. Various other products can be made using various foaming techniques with expansion factors ranging from low (1.1 times) to high (20times).
In the current automotive industry, sponge rubber, based on its properties of air bubbles, is known to be a useful material for achieving weight-reduction and noise absorption requirements. We have our strength in these areas of business.
