Sealants are necessary in a variety of different facets of life to ensure the preservation of certain products or machinery. This is because sealant are substances that essentially block the passage of fluids or air through the surface, joints, or opening in certain materials, machinery, or piping. There are a wide variety of sealants depending on your needs. If you have heard of hermetic sealing and wondered, what is hermetic sealing, you are in the right place. Below you will find more information

Stick-slip is a common phenomenon that can occur in seals due to uneven friction between objects sliding across each other.
This repetitive start-stop movement or vibration known as stick-slip can cause major issues and even failure of mechanical systems, including seals. However, proper seal design and knowing what to look for can help you avoid stick-slip in your machinery’s seals.
Here’s why stick-slip happens and how you can prevent this problem in your

A common question that comes from many customers is: “Can you tell me which O-ring compound meets this ASTM D2000 callout?” It’s understandable, since at first glance, the ASTM D2000 callout can be intimidating for determining the type of O-ring material. However, the ASTM D2000 is a very useful tool to quickly specify requirements for O-ring materials, and is standardized so it is easy to interpret industry wide. So, what is the

VICTREX CT™ 200
VICTREX CT™ 200 is a High-performance thermoplastic PEEK polymer suitable for dynamic sealing applications at very low temperatures.
As the latest member of the VICTREX CT™ PEEK polymers, the 200 grade series exhibits improved sealing over a wider range of temperatures, compared to commonly used materials such as PCTFE. It does so at low temperatures on account of its greater ductility, and at high temperatures due to its superior creep resistance. It

Extrusion Gap Seal
The Clients Issue
The client came to our partners at Eclipse with a challenge: for the sealing requirements of their existing spring energized seal to provide optimal performance in a “worst case” scenario.
The client had an issue with outside seals failing at the deepest possible ocean depth and at max temperature of the instrument.
When tested, the seals were failing at the max temperature of 300°F.

More often than not, the process of parts material selection and/or development can get fairly involved. To summarize: it’s similar to a game of pros vs cons where so many different variables come into play. In the case of TPE, the principle is no different. Factors such as meeting the performance requirements for a specific application, economic assessments, and processing issues, should all be reviewed in order to make the optimal choice. Looking at the qualities and considerations

Shortly after the discovery and use of PTFE as a seal material, the need for a secondary energizing method became apparent. Unlike rubber or urethane which possess elastic and spring-like properties, PTFE will not return to its original state once deformed.
This is obviously not a desirable trait for sealing material, especially in dynamic sealing applications.
