Inflatable silicone seals: technical expertise from PROGRESS Silicones
In many highly demanding industries — whether agri-food, nuclear, space or pharmaceutical — the question of dynamic sealing is central. When mechanical constraints prevent the use of conventional static seals, a solution is required: the inflatable seal, also called pneumatic seal. Designed to adapt to its environment by inflation, this type of seal ensures total hermetic insulation against liquids, gases or dust. However, very few players in Europe really master its design and manufacture. At PROGRESS Silicones, this expertise has been at the heart of our know-how for more than 30 years. In this article, we offer you a complete overview of silicone inflatable seals, from their characteristics to their areas of application, including the stages of their manufacture.
