Fire-Resistant Fiber for Concrete and Tunnel Applications | PIONEER®
High-Performance Anti-Spalling Polypropylene Fiber for Concrete
Deploy advanced structural fire protection for tunnels, high-rise buildings, underground facilities, and critical infrastructure. PIONEER® HPM® FR fibers minimize explosive spalling, improve evacuation safety, and enhance concrete durability under extreme heat events.
What is PIONEER® HPM® FR Fire-Resistant Fiber?
PIONEER® HPM® FR is a high-performance fire-resistant polypropylene fiber engineered to prevent explosive spalling when concrete is exposed to fire. As temperatures rise, the hollow fibers melt and create micro-channels that relieve trapped vapor pressure. This reduces the risk of sudden concrete failure and increases structural fire endurance.
Ideal for:
-
Tunnels & underground structures
-
High-rise evacuation routes
-
Subway systems
-
Fire-rated structural concrete
-
HPC & UHPC exposed to fire loads
