Spalling Protection Fibres: How They Work
In the event of a fire, the PP-fibres embedded in the concrete melt, creating a permeable capillary network which permits escape of the gases evolved. Special PP grades with low melt viscosity rates provide enhanced fire resistance as shown by tests conducted with concretes of various types.
The results: Reduced spalling, Upgraded structural safety.

What sets PB EUROFIBER HPR apart from conventional PP anti-spalling fibres is its outstanding flow capability in the molten state.
In the event of fire, this ease of flow permits quick and efficient formation of a permeable capillary network which vents off vapour pressure from the concrete, therefore reducing more efficient spalling.
