A kneader that can be heated by steam was installed early on. We started with the production of compounds blended from rubber and resin. Production in small lots of 75L units is possible. Additionally, we can achieve mixing that is difficult with a typical resin kneader, the "extruder." We have now also added kneaders that can be heated with oil, expanding the types of resins that can be mixed. We ensure reliable quality production from prototyping to mass production within a short lead time. For more details, please contact us.

Color compounds refer to the refining of rubber that is not black. Since carbon black is commonly used as a reinforcing agent for rubber, most of the demand for rubber refining has been for black products. At Caseley, we started our business in colored refining other than black in 1983 to meet the diverse needs of our customers. Black is made by adding a black coloring agent.

The limit of softness for butyl rubber is considered to be around 15° on the JIS hardness A scale. However, with the recent advancements in IC integration, there is a demand for "softer" materials for vibration damping and shock-absorbing materials in various electronic devices and precision instruments. In response to this, our company has developed ultra-low hardness to low hardness butyl rubber with a JIS hardness of A0 to 10°. This allows for hardness below 10°, which has traditionally been difficult to compound, making it suitable as a vibration damping and shock-absorbing material for electronic devices, weighing instruments, and vibrations in low-frequency ranges. Additionally, it demonstrates excellent performance as waterproof and dustproof materials, as well as airtight materials, taking advantage of its sealing properties.
