Fluoroelastomer Specialists
As detailed in an article by SAE International, “Low Temperature Sealing Capabilities of Fluoroelastomers,” traditional tests like brittle point and glass transition provide insights into the low-temperature properties of fluorohydrocarbon elastomers (FKM). However, these tests may not fully predict the sealing performance of fluoroelastomer molded products, such as O-rings, in cold environments.
Recent advancements in static O-ring testing have enabled a closer look at how variables like polymer type, compound design, seal interference, and environmental factors affect the low-temperature sealing capabilities of FKM compounds. This improved testing method has highlighted the potential of new, low-temperature-resistant fluoroelastomer types that maintain sealing integrity even under extreme conditions.
Key Insights for Improved Sealing in Low Temperatures:
- Advanced Testing Techniques: A static O-ring testing apparatus helps simulate real-world sealing performance in low temperatures, surpassing the predictions of traditional laboratory tests.
- Influence of Compound Design: The specific formulation of FKM compounds, including polymer selection and additives, plays a significant role in their sealing capability.
- Automotive Applications: These advancements are particularly valuable for automotive engineers, offering improved sealing solutions for fuel injection and fuel handling systems in cold weather.
The development of fluoroelastomers with enhanced low-temperature sealing properties represents a significant step forward for industries requiring reliable sealing solutions in harsh conditions.
