PP FIBRE

Polypropylene Fibre (PP Fibre)

PP Fibre, also known as Polypropylene fiber is derived from 85% propylene. PP is manufactured from Propylene gas, using a catalyst such as titanium chloride. This synthetic fibre is the first form of stereoregular polymer and has multiple industrial uses.

PP Fibre is thermoplastic in nature. This makes the material pliable at a certain elevated temperature and solidifies when cooled. Unlike Polyethylene, PP is a white rugged material with huge chemical resistance. PP belongs to a group of Polyolefins and is a by-product of petroleum. This makes it crystalline and non-polar. It also is harder and has better heat resistance.

PP is also processed into thin sheets that are used for packaging. They are also utilized for carpets & clothing.

PP is used in industries as it can be converted to fibre/ filament by the traditional melt spinning process. This makes them an important material in the synthetic fibre market.

PP Fibre has two different variations:

1) Macro PP Fibre

Macro synthetic fibres or ‘structural’ synthetic fibres, are made from a blend of polymers. Macro PP Fibres was first used as an alternative in sprayed concrete. With continual research, Macro Fibres have shown efficient results in the construction of ground-supported slabs and a wide range of other applications, especially concrete strengths.

They have high tensile strength and a relatively high modulus of elasticity. Macro Fibres have a higher post-cracking capacity of concrete and are used in ground-supported slabs (both internal and external), sprayed concrete, small precast concrete units and composite floor slabs on steel decking.

Highly utilized in marine & coastal structures, Macro PP Fibre does not suffer the problems of staining and spalling that can result from the corrosion of steel. In addition, because they are non-conducting, they have been used in tram and light railway developments.

2) Micro PP Fibre

Micro PP Fibres are used to change the properties of the fresh concrete. Micro Fibre helps increase the homogeneity of the mix.

This thus stabilizes the movement of solid particles and blocks bleed water channels. Micro PP Fibres also help in reducing plastic settlement. Due to their ability to reduce bleeding, Micro PP Fibres can maintain the original water/cement ratio of the surface mortar. Giving the construction better ductility & resistance to abrasion.

Micro PP Fibres can be used for equal distribution of stress impact. Micro PP Fibres reduce the spalling of concrete in a fire.

PP Fibre Reinforced Concrete

PP Fibre Reinforced Concrete offers various advantages in the mechanical characteristics and economic aspects of construction. This is due to PP Fibre’s feature of adding toughness, flexural strength, tensile strength & impact strength. PP Fibre is also cheaper compared to other equivalents, abundantly available and has consistent quality.
