Fire-Resistant Fiber for Concrete and Tunnel Applications | PIONEER®
High-Performance Anti-Spalling Polypropylene Fiber for Concrete
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

Looking for Cost-Effective High-Performance Concrete Reinforcement?
High-performance fibers such as PVA fiber, basalt fiber, carbon fiber, and aramid fiber are widely used in high-performance concrete (HPC) and UHPC.
They deliver excellent strength and toughness—but in real projects, their high cost limits large-scale application, making them suitable mainly for specialized or high-end use.
