Technical specifications of polypropylene fibers

Polyvinyl alcohol coarse fiber is mainly used in ultra-high performance concrete and high ductilityconcrete.Its main characteristics are high strength,high modulus,low elongation,wear resistance,acid and alkali resistance,good weather resistance,good   affinity and bonding with substrates such as cement and gypsum,and non-toxic,pollu- tion-free,non damaging to human skin.It is one of the new generation of high-tech green building materials.

Instructions for Use 

Polyvinyl alcohol coarse fiber reinforced concrete is a cement-based composite material reinforced with PVA fibers.Compared to ordinary concrete,it has higher tensile strength,flexural strength,good impact resistance,fatigue resistance,impermeability,waterproofing,frost resis-   tance,and the ability to suppress early plastic shrinkage cracks,thereby improving the durability of concrete.
Polyvinyl alcohol crude fibers  have good  affinity and acid  resistance with  cement.Mainly used for profiles or plates in concrete products to suppress micro cracks caused by plastic
shrinkage of concrete.This product is pollution-free and is gradually replacing asbestos as a new type of material.It is also widely used in engineering fields such as railways,water conservancy, ports,wind power,bridges,tunnels,etc.
