PP Fiber Macro Synthetic Fiber Reinforced Concrete Mortar Polypropylene Plastic Building Materials
Product Description
Features
- Provides good impact,fatigue,shrinkage control and ductility in all grade concretes.
- Cost saving,Is easier to use,to disperse and safe to handle.
- Can be used in highly corrosive circumstance.
- The surface has been embossed,which greatly improves the cohesive force between fibres and concrete,and also boosts shrinkage resistance and crack resistance.
- The toughness of macro synthetic fibre is less stronger than steel fibre.But test has shown slabs on grade and pre-cast concrete predominately require a dosage rate of between 25kg-40kg of steel fibres per cubic meter, in comparison,using between 3kg-10kg of macro synthetic fibre per cubic meter of concrete. Synthetic fibres achieve greater strength and ductility in the matrix.

Polypropylene mesh fibers
Description:
Polypropylene mesh fiber, also known as polypropylene fiber mesh, is made of polypropylene as the raw material, through a special production process.Its appearance is mostly a network structure made of multiple fiber single filaments cross-linking. After the addition of functional maternal modification and special surface treatment technology, it has excellent dispersion and good hydrophilic properties in concrete.When polypropylene mesh fiber into the concrete, in the process of concrete mixing, the lateral connection between the fiber single filament by the concrete rubbing and friction and tear, forming fiber single filament or mesh structure fully open, can have more than 7 million fibers per cubic meter of concrete, its rough tear edge between the fiber and concrete has excellent grip, thus improve the performance of the concrete.
