Modified Polyphenylene Ether Usage
1.NORYL SA90 resin is a modified low molecular weight resin with increased hydroxyl functionality.
2.It is designed specifically for use as a reactive component in epoxy and cyanate ester thermosets in electronic, coatings, adhesives and composites applications.
3.It has outstanding solubility in toluene methyl ethyl ketone (MEK) and a low solution viscosity.
4.Used to enhance the performance (e.g. thermal, dielectric, mechanical, flame retardancy, and moisture uptake properties) of epoxy resins used in electronic packaging which include PCB laminates, copper clad laminates, epoxy prepregs, and protective coatings as well as various other composites applications.
