These diaphragm sealing devices, when molded of LSR material, improve design function and cost efficiency over similar components molded of lesser grade compounds. The thin-walled diaphragms are used in a broad range of healthcare related applications, from dispensing and fluid filtration systems to purification systems. These component seal applications require long term seal life where temperature variation and resistance to aging are important design considerations. Also, uninterrupted operation for extended periods is important in these applications. LSR has good heat resistance to +180°C and good flexibility down to -45°C. It also has good electrical insulating characteristics and resists UV radiation and weathering.
Additional advantages of these LSR diaphragms from Minnesota Rubber and Plastics include a very clean molding process with no material pre-processing. Depending on part complexity, components can be molded with minimal flash. LSR material has repeatable, short cycle times and provides reduced or eliminated secondary operations. Compared to other materials and processes, this means lower labor content due to reduced manufacturing steps.
