Phosphorous Acid (CAS 13598-36-2): A Buyer’s Guide to Grades, Applications & Sourcing

News / By

Phosphorous acid (CAS 13598-36-2) is one of those quiet workhorse chemicals that sits upstream of several large industries: phosphite fungicides that protect high-value crops, phosphonate scale inhibitors that keep cooling towers running, and a family of polymer additives and synthesis intermediates. For procurement managers and formulators, however, buying it well is not trivial. Grades, specifications, …

High-Frequency High-Speed CCL: Resin Technologies, Key Parameters & Future Outlook

News / By

The copper-clad laminate (CCL) beneath a printed circuit board does more than provide mechanical support — at frequencies above a few gigahertz, the resin system embedded in the laminate becomes a determining factor in signal integrity, energy efficiency, and the operating envelope of the entire electronic system. As 5G networks push into millimetre-wave bands, AI …
