초록

The present invention provides nonwoven glass composites formed from an essentially boron free glass wool and an essentially boron free chopped glass fiber, used as a reinforcing material. The nonwoven glass composites are suitable for air filtration apparatus and can be used in the semiconductor industry where the elimination of boron from clean rooms is of importance.
