Pro-Expand Glass Sheets

The Pro-Expand Glass Sheet is an advanced insulating material reinforced by a glass mat, designed to provide excellent rigidity and insulating properties. Its core feature lies in its thermal expansion capability: upon heating, the fiberglass mat rapidly expands to fill surrounding spaces. During this expansion, the plate generates small interspaces that easily absorb varnish, allowing it to cure seamlessly together with other components. Impressively, its thermal expansion rate exceeds 80% under 180℃.

Key Benefits & Product Application Cutting this sheet into pads and utilizing them as insulation strips effectively solves the common problem of motor slot wedge looseness caused by long-term operation. This innovative solution ensures reliable motor operation, significantly improving both the performance and the service life of the motor.
