Whereas NE glass has lower contents of alkaline earth metals (such as CaO and MgO) than general-purpose E glass used for composite materials, it has a higher content of boric acid (B₂O₃). As a result, its fiber has low dielectric constant and low dielectric dissipation factor although it has characteristics similar to those of E glass. NE glass is a new technology developed by Nittobo independently.
