The medical device industry is facing evolving challenges in finding suitable sealing solutions for new and improved designs. We will focus on customizing spring energized PTFE seals as a potential solution to the sealing challenges in the medical industry.

PTFE is a popular choice for spring energized seals used in medical applications for several reasons. One is that some grades of PTFE have been approved by the FDA as USP Class VI materials. It can resist various corrosive chemicals, has extremely low friction, and maintains its key characteristics, including strength at various temperatures and pressures. It can be disinfected by using methods such as steam and EtO (ethylene oxide), and has hydrophobicity and oil repellency.

As you may know, spring energized seals can achieve sealing at low pressure because the spring applies outward pressure to the lip of the seal against the shaft or bore. With pressure increases, the pressure itself takes over from the energizing spring and achieves a tight seal. The result is an effective sealing solution.

PTFE seals are common in the medical device industry and can be used in medical devices, drug delivery systems, and orthopedic applications.

Customized sealing design can meet the complex needs of the medical device industry. This includes customized engineering of polymers (including fillers), unusual sizes or geometric shapes, special spring materials, and so on. In addition, PTFE helps with manufacturing processes, such as providing high-precision and precision machining.

PTFE seals are popular in the medical device industry for a various reasons, including their low friction, chemical resistance, and excellent performance in a variety of pressure, temperature, and speed situations. Spring-energized PTFE seals provide a reliable sealing solution that is effective even in low-pressure environments. Even if an off-the-shelf energized PTFE seal won’t meet your needs, you can look into a custom-designed energized Teflon seal tailored to your requirements and specifications.
