Latest Patents

One of Nakata's latest patents is a chloroprene rubber composition. This innovation improves the cold resistance of chloroprene rubber by blending an ester derived from a specified glycol component and a specified fatty acid component. This method ensures that the other physical and chemical properties of the rubber remain unaffected. Notably, the ester is not extracted with oily matters such as oil or grease, allowing the resulting chloroprene rubber composition to maintain its cold resistance even after exposure to such substances.

Another significant patent is for a dust boot with a multiple layer construction of bellows. This dust boot is designed for a constant velocity universal joint and features a bellows-shaped boot made of chloroprene rubber, which substantially excludes wax. Additionally, it has a polyamide resin coating layer that exhibits excellent wear resistance, formed on the outer surface of the bellows-shaped boot without peeling. A primer layer made of a mixture of chloroprene rubber and isocyanate compound is also included to ensure that the coating layer adheres properly to the bellows-shaped boot.
