Using engineered thermoplastic mechanical components is at the forefront of modern technology. However, researchers continue to explore newer, better materials for future production. So what future materials will seals be made from?
What Future Materials Will Seals Be Made From?
We have come a long way from the first seals made using materials like resins, beeswax, and even old rope. Modern thermoplastic materials are built to last and withstand extreme temperatures without failing. But there is always room for improvement.
What Future Materials Would Require
Some requirements for future materials will not change much, while others will change based on current needs and regulations. Industries may change, but
Top factors being:
- Resistance to extreme conditions of heat, pressure, and chemicals
- Meeting environmental regulations
- Focusing on recyclability and lower carbon footprints
- Enhanced performance in EVs, aerospace, and industrial settings.
Surviving Extreme Conditions
As aerospace efforts expand, we need materials that can survive extreme environments. To this end, materials like advanced composites and ceramics will become central. These materials can handle temperature and pressure extremes while also showing excellent chemical resistance.
Additionally, expect to see more high-performance elastomers. These next-gen synthetic rubbers are designed for advantages like:
- Enhanced thermal stability
- Excellent elasticity
- Improved performance in electric vehicle systems
A Push for Sustainability
Future sealing materials will likely need to be from sustainable resources. Currently, research is underway for developing bio-based polymers and using recycled materials. Both of these options offer more sustainable paths forward, while also meeting the durability requirements for safe seals.
Plant-derived polymers in particular open the door for biodegradable options. Currently, petroleum-based products are the most common. While extremely durable and cheap to make, these have a lifespan measured in millenia before they would begin decomposing.
Regulation Shifts
Regulation changes will encourage a shift to nonfluorinated materials. Moving away from PFAS (commonly known as “forever chemicals”) will be a major shift moving forward. Alternatives may take the spotlight, such as specialized graphite and polyphenylene sulfide (PPS). Legislation likely will continue in these directions, ensuring more sustainable and environmentally aware practices in the near (and hopefully far) future.
Emerging Technologies
Silicon Carbide
Current research shows that materials with silicon carbide demonstrate several benefits, including:
- Improved thermal conductivity
- Better dissipation of heat-generated friction at sealing interfaces
- Enhanced thermal shock resistance
Dry Sealing Technology
Dry-running seals stand out as a fundamental change in approaches to mechanical sealing. Historically, most chemical and process industry applications relied on seals lubricated by barrier fluids. Modern efforts are seeing advances in self-lubricating materials that have made dry-sealing possible and effective for many environments.
3D Printing on Center Stage
Additive manufacturing (also known as 3D printing) will enable complex, customized seal designs on smaller scales. This cuts down on waist while maintaining optimized performance due to customization.
Smart Seals & Coatings
Integrating elements like sensors and surface treatments will improve seal health. Smart monitoring can cut down on seal failure to improve real-time efficiency.
Liquid Sealants
Liquid seal alternatives are growing in use, particularly in EV battery packs. Research continues to explore expanded utility versus traditional gaskets.
Water-Lubricated Systems
PFAS-free seals compatible with water-based lubricants are growing. These avoid depositing forever chemicals while also maintaining high efficiency.
