Today’s heavily used faucets, water softeners, and toilets require long-term seal life that doesn’t degrade over time. Static face seal gaskets custom designed and molded of liquid silicone rubber (LSR) by Minnesota Rubber and Plastics provide superior strength and improve design function in most plumbing related products.
“To maintain uninterrupted plumbing operation over extended periods durability is extremely important,” reports Aron Yngve, Medical Market Director of Minnesota Rubber and Plastics. “Premature failure with traditional elastomer seals is common because chlorinated water degrades them over time. Minnesota Rubber and Plastics’ LSR static face seal gaskets address this issue by providing high resistance to the chloramine contained in the drinking water of most municipalities.”
Available for both radial and axial applications, these LSR sealing devices are well suited for environments where temperature variation and resistance to aging are important design considerations. The typical liquid silicone rubber properties for grades ASTM DZZ40 durometer is shore A of 20 – 80 with a tensile strength for ASTM D412 of 1150 – 1750 psi. These grades have high heat resistance to + 180°C and good flexibility to – 45°C. They have excellent electrical insulating characteristics and resist UV radiation and weathering.
Additional design advantages to these LSR static face seals include: ability to handle high pressure limits with thinner cross sections; very clean molding process with no material pre-processing needed; minimal flash with very little gate or flash material waste; short repeatable cycle times and reduced secondary operations.
LSR static face seals from Minnesota Rubber and plastics are a more cost-effective sealing solution when compared with other materials and processes.
