At the heart of every high-performance Bal Seal® is a jacket material that delivers the perfect combination of friction and sealing effectiveness. Drawing from more than 60 years of engineering and material science experience, we’ve developed a proven offering of premium polymers to address every application requirement. We combine these materials with innovative geometries and Bal Spring® energizer technology to solve sealing challenges nobody else can.
Why Material Selection Matters for Sealing Performance
Seal performance depends heavily on selecting the right polymer for friction, wear, temperature, pressure, and media compatibility. Bal Seal Engineering offers proven material families for a broad range of operating conditions.
Application-Matched Formulations
From PTFE to PEEK, UHMWPE, and specialty polymers, each family addresses different operating requirements.
Regulatory & Industry Options
Material options are available for medical, food, cryogenic, and demanding industrial environments, including USP Class VI, FDA-related, and other application-specific requirements.
Custom Material Development
Bal Seal Engineering can help tailor materials to application-specific combinations of wear, chemical resistance, and mechanical performance.
Seal Materials FAQs
Material selection depends on friction targets, media compatibility, temperature, pressure, wear conditions, and lifecycle expectations. Bal Seal Engineering can help evaluate the right option for your application.
PTFE is commonly selected when low friction and broad chemical compatibility are high priorities.
PEEK is often selected for applications requiring higher stiffness, dimensional stability, and stronger mechanical support under load.
UHMWPE is often chosen where low friction and strong abrasion resistance are both important.
Specialty polymers are used where cryogenic performance, extreme temperatures, radiation resistance, or unusual chemical environments push beyond standard material families.
Yes. Bal Seal Engineering can recommend or develop material solutions based on the requirements of your sealing application.
