High Strength Composite Bottom Guard

INTRODUCTION
Composite Bottom Guard primary function is to serve as a robust barrier against mechanical impacts, wear, and environmental stress, effectively extending the service life of the equipment it protects. In addition, the low thermal conductivity of the material provides excellent insulation, making it suitable for applications where temperature control is critical.
