Ha-Be PP-Faser 15µm HFP

Polypropylene fibre for optimising concrete's fire resistance

Item No. 4504


Ha-Be PP-FASER 15 μm HFP is a building inspectorate approved polymer fibre which is especially designed for increasing the fire resistance of cementitious construction materials.

The ultra-fine, synthetic fibre melts at high rising temperatures and forms void in the concrete. In the event of a fire the vaporised water pressure escaping from the heat source can escape into them.

Concrete spalling can thereby be reduced or retarded.

Application range of the micro fibre:
  • General building constructions
  • Concrete applied in underground constructions (shotcrete, tubbing segments and tunnelling)
  • Industrial floors
  • Agricultural concrete
  • Precast concrete products
  • Pavements, internal and external slabs
  • External Concrete Hardstandings
  • Screed
  • Foundations and basements

Product features of the micro fibre:
  • Optimisation of green strength
  • Reduction of shrinkage cracks
  • Improved resistance against shock stress
  • No corrosion
  • Provides improved durability
  • Optimisation of concrete's fire performance


Having good dispersing properties Ha-Be PPFASER 15 μm HFP can be dispersed easily, homogeneously and three-dimensionally throughout the fresh concrete.

The degree of fiber finesse and its frequency attains a homogeneous stress spread in concrete and minimizes shrinkage cracks significantly.


Recommended dosage range: 0,6 – 2,0 kg/m3.
