Robert--Very informational.  Excellent post.   Am I correct in saying the Tg temperature is somewhat like the "triple point" for other materials?   Would this be a decent analogy?  Also, I'm assuming all adhesives have a Tg temperature.  In looking at the adhesives I use and see used on a daily basis, we are very concerned that we apply adhesive to a part and adhere that part to a substrate before that adhesives "skins over".    The only way for us to insure compliance with our customers "pull test" requirements.

Thanks for a very educational piece of material. I learned quite a bit, and now have a much btter understanding of what the temperature ratings of epoxy materials are all about.

The increased adoption of wireless technology for mission-critical applications has revved up the global market for dynamic electronic general purpose (GP) test equipment. As the link between cloud networks and devices -- smartphones, tablets, and notebooks -- results in more complex devices under test, the demand for radio frequency test equipment is starting to intensify.
Much of the research on lithium-ion batteries is focused on how to make the batteries charge more quickly and last longer than they currently do, work that would significantly improve the experience of mobile device users, as well EV and hybrid car drivers. Researchers in Singapore have come up with what seems like the best solution so far -- a battery that can recharge itself in mere minutes and has a potential lifespan of 20 years.
