Description

<p>As typical seals used for food machinery, this paper presents oil seals which are a kind of dynamic seals and ferrule gaskets which are a kind of static seals. These seals are required to comply with the Food Sanitation Act and to have high durability against the special oils and detergents peculiar to food machinery. Especially, in the case of oil seals, it is necessary to improve the sealing properties against low-viscosity water, and in the case of ferrule gaskets, it is necessary to take measures against the odor of various flavors. In response to these requirements, the development of fluorine-based rubber materials by special compounding and the improvement of the seal structure have been promoted.</p>
