Dainaga's "Super Cork," which utilizes rich experience and technology in cork manufacturing. Here, we introduce its characteristics in terms of compressibility and resilience. 【Characteristics】 <Compressibility and Resilience> Cork contains about 80% air and consists of independent cellular structures made up of millions of mesh-like cells per cubic centimeter. When cork is compressed, the air is compressed, causing deformation that occurs only in the direction of compression and not laterally. In contrast, rubber does not have a change in volume, so its compression results in a change of shape and lateral flow. *For more details, please download the PDF or feel free to contact us.

Dainaga's "Super Cork," which utilizes extensive experience and technology in cork manufacturing. Here, we introduce its characteristics in terms of sealing performance. 【Characteristics】 <Sealing Performance> Despite stress relaxation occurring, Super Cork can maintain its sealing performance during initial tightening for a long period (10 to 20 years) due to the unique property of cork, where the adhesion to the flange surface increases over time and with heating. *For more details, please download the PDF or feel free to contact us.

Dainaga's "Super Cork," which utilizes extensive experience and technology in cork manufacturing. Here are its characteristics in terms of heat resistance and weather resistance. 【Characteristics】 <Heat Resistance> The maximum temperature limit for use is 110°C to 150°C, but it can be used at temperatures 10°C to 15°C higher in lubricating oil. However, this is not the case depending on the usage conditions (internal liquid, internal pressure, etc.). <Weather Resistance> Due to differences in usage conditions, it is less susceptible to the effects of complex combinations of atmospheric elements (oxygen, ozone), sunlight, water, temperature, etc. *For more details, please download the PDF or feel free to contact us.
