Latest Patents
One of Tomonoh's latest patents is for a cross-linked rubber and its production method. This innovative rubber improves the long-term sealing properties of seal members in high-temperature and high-pressure environments. The cross-linked rubber is created through the cross-linking of a composition that includes fluororubber, carbon black, carbon nanotubes, and an organic peroxide cross-linker. It boasts a 50% modulus of 5 MPa or more, a compression set of 80% or less after 500 hours at 230°C, and a minimal change in elongation at break after heat aging.
Another notable patent involves a carbon nanotube-elastomer composite material, along with the seal and sealing materials produced from it. This composite is produced by dispersing carbon nanotubes in an elastomer, ensuring that the nanotubes have a diameter of 20 nm or less and consist of 10 or fewer layers. The elastomer is designed to form a continuous network that enhances its properties when subjected to high temperatures.
