Differentiation Through In-House Adhesive Development
One of NOK’s signature products, the oil seal, is typically made by combining rubber, a metal ring, and a spring. Adhesives are used to integrate these different materials into a single unit. However, bonding dissimilar materials such as rubber and metal is technically challenging, and oil seals must also perform reliably in demanding environments. For instance, they need to maintain adhesion while exhibiting heat and oil resistance, even at temperatures exceeding 100°C. To meet these stringent specifications, NOK has developed its own in-house adhesives for over 60 years.
