FOX POLFIBER M12 is a 100% polypropylene fibre material that wraps around aggregate through its fibrillated fibre network structure, preventing crack formation and increasing mechanical strength in concrete and mortar mixes. It is reliably used in industrial floor, precast, shotcrete, and tunnel-dam projects.

Product Description
FOX POLFIBER M12 is a 100% polypropylene fibre material that wraps around the aggregate in concrete and mortar mixes through its fibrillated fibre network structure, forming a composite matrix. With a 12 mm fibre length and rectangular cross-section geometry, the product disperses easily throughout the concrete mix; it prevents crack formation and imparts flexural strength, impermeability, and resistance to fire damage to the concrete. The transparent fibre, with a density of 0.91 g/cm³, can be added to fresh concrete at a batching plant or on site; a minimum of 1 pack (600 g) per 1 m³ of concrete is recommended.
Key Benefits
- Forms a homogeneous concrete matrix by wrapping around the aggregate through its fibrillated network structure.
- Significantly reduces crack formation caused by plastic and drying shrinkage.
- Increases the flexural strength of concrete slabs, enhancing heavy load-bearing capacity.
- Reduces concrete permeability, ensuring long-term durability.
- Provides additional resistance to fire damage in concrete.
- Easily applied at a batching plant or on site; integrates into the existing mixing process.
Advantages
- Wraps around aggregate through its fibrillated network structure.
- Prevents crack formation.
- Has strength-enhancing properties.
- Effectively controls diffusion within concrete.
- Suitable for floor applications subject to heavy loads.
- Reduces bleeding.
- Reduces concrete permeability.
- Increases the flexural strength of concrete slabs.
- Increases concrete resistance to fire damage.
Usage Areas
- Industrial floor applications

Application Steps
- 1
Batching Plant Application
It is recommended to add FOX POLFIBER M12 directly to the concrete mix at the batching plant. If mixing is carried out at the plant, the product is added to half of the mixing water to allow it to disperse; the remaining concrete components are then added to the mix together with the remaining water.

Adding to Fresh Concrete on Site
If it is necessary to add the product to fresh concrete on site, the mixing time should be increased by an additional 3–5 minutes to ensure homogeneity.
Important
The product must be stored between +5°C and +30°C, away from direct sunlight, in a cool and dry environment. It must be protected from frost.
Important
If material stored in unsuitable conditions freezes, it should be left at room temperature without applying direct heat until thawed, then mixed mechanically until homogeneous. Compressed air must not be used during mixing.
Important
If added to fresh concrete on site, the mixing time should be increased by an additional 3–5 minutes to ensure homogeneity.
Critical
Approaching storage and application areas with open flame is dangerous; these areas must be adequately ventilated.
Important
During application, appropriate work clothing, protective gloves, goggles, and a mask in accordance with occupational health and safety regulations must be worn.
Critical
The product must not be allowed to come into contact with skin or eyes. In case of contact, wash immediately with plenty of water and soap. If swallowed, seek medical attention immediately.
Important
Food and beverages must not be brought into application areas. The product must be stored out of reach of children.
Information
For short-term storage, pallets must not be stacked more than 3 high, and a first-in, first-out dispatch system must be applied. For long-term storage, pallets must not be stacked on top of each other.
Information
Shelf life is 24 months from the date of manufacture under correct storage conditions. Opened packages can be resealed and used within the shelf life.
Information
The technical values above are given for conditions of +23°C and 50% relative humidity. Higher temperatures shorten the time; lower temperatures extend it.
