The 7637 Impregnated Fiberglass Fabric is a high-quality E-glass woven material designed for applications requiring enhanced mechanical strength, thermal resistance, and dimensional stability. This customized version features a high areal weight , combined with uniform resin impregnation to ensure superior handling, consistent resin content, and improved laminate performance.
With its balanced structure, smooth surface, and excellent wet-out characteristics, the 7637 impregnated fabric is widely used in aerospace, electronics, industrial insulation, and composite reinforcement applications.
Excellent electric insulation
Fire-resistance
High temperature resistance
Weather resistance
Highstrength
High modulus.
