Concrete reinforcing pp stable polypropylene long fibers
The instructions, specifications and applications-Concrete reinforcing pp stable polypropylene long fibers
1) 2-3 mm fiber
2-3 mm fiber can be used as putty, plaster, dry mortar with good crack resistance.
2) 6-12 mm fiber
6 and 12 mm fiber, commonly used in plaster, surface coat, leveling layer, base concrete or thermal insulation mortar, etc.
Introductions-Concrete reinforcing pp stable polypropylene long fibers
The polypropylene fiber is a synthetic fiber made by adding master batch into the raw material of 100% modified polypropylene before blending, spinning, stretching, and special processes of electrostatic prevention and antiultraviolet treatment, etc. As a fiber dedicated to concrete and mortar, it can effectively control the cracks of concrete and mortar caused by shrinkage, desiccation and temperature fluctuation, and is innoxious, acid-proof and alkali-proof, antimagnetic and anticorrosion, and has strong bonding force with cement, thus able to remarkably improve the crack resistance and impermeability and resistance to abrasion and enhance the concrete toughness, thereby prolonging the service life.
