Internal bonding strength in plastic testing machine

The internal bonding strength in the plastic testing machine,The indicators are the key to reflecting the quality of the glue between the fibers inside the substrate. They should be ≥1.0MPa, and the low strength will cause product stratification. The higher the internal bonding strength, the better the floor can withstand temperature changes and avoid cracking. Only when the base material is a floor with relatively dense wood can it ensure that it does not crack or deform under high temperatures for a long time.
