Polypropylene Fiber

Product Detailed

Control the microcracks resulting from ductile shrink of concrete,dry shrink and variations of temperature.

Polypropylene Fibers effectively control the microcracks resulting from ductile shrink of concrete,dry shrink and variations of temperature, prevent and constrain the from and development of cracks. As a new kind of reinforcement fibers for concrete,the polypropylene fibers have becoming a focus on research and application of fibrous concrete science after glass fiber and steel fibers.
Properties of Polypropylene Fibers

Acide and Alkaly Resistance: Strong

Length of Fiber: 10/12/15/19

Density: 0.91g/cm3

Tensile strength: 400MPa min

Melting Point: 160-175.C

Function of Polypropylene Fiber Reinforced Concrete
   Polypropylene Fibers have obvious advantages of its single fiber slim in length,large in amount after fully spread out in concrete,comparing with steel fibers,and they are characterized by their resistance to moisture and chemicals,and low in elastic modulus so made improvements in concrete performance in the following aspects:
   Constrain cracks resulted in ductile shrink
   Improve permeability
   Improve abrasion resistance
   Improve tensile strengthcapability of impact and fatigue
   Prevent and stave off  main structural bars from erosion
   Replace other forms in controlling nonstructural cracks
Applications of Polypropylene Fibers
Concrete pavementsbridge decksAirport runways and Manufacturing facilities
Tunnelwalls and top deck of mining tunnel
Riverway dam  reservoir
Military infrastructures pier dock
Highway barrier walls Concrete edging
