The most effective sealing technique between moving or stable surfaces is pneumatic seals. They relax and contract in a way which guarantees full and reliable sealing.
Pneumatic sealing is a homogeneous elastomer sealing of high flexural module and high tensile strength. The sealing is intended to be mounted in the assembly grooves. They relax and contract along with filling and emptying of the groove sealing.
Strict dimensions of groove gap are crucial during design process as well as during production of suitable sealing for a specific use.
Properties of pneumatic seals: (Pneumatic seals properties)
