Polypropylene Twisted Fiber, also known as PP Twisted Fiber and PP Bunchy Form Fiber, is a synthetic fiber that is widely used in the construction industry. It is made from high-quality polypropylene materials and is specifically designed to enhance the properties of concrete.
PP twisted fiber has a unique twisted design that allows it to disperse evenly in concrete. This results in improved mechanical properties such as strength, toughness, and durability. It is available in various lengths, diameters, and color options to cater to different construction needs.
PP twisted fiber is an alternative product developed for steel fiber. Compared with steel fiber, it has the characteristics of acid-base corrosion resistance, high strength, easy dispersion, easy construction and no damage to mixing equipment. It has the advantages of high fracture strength, good dispersion in concrete and strong grip force. It can replace steel fiber for crack resistance and reinforcement of cement concrete.
Product Features:
- Highly alkali resistant
- High tensile strength and high modulus
- Lightweight but highly durable
- Water resistant
- Excellent resistance to chemicals

Dosage:
When the requirements for crack resistance are high, it is recommended that the dosage of concrete per cubic meter is not less than 3kg (volume ratio 0.3%). In general, 0.8kg of this fiber and 0.4KG of mesh fiber can be used for crack prevention and reinforcement.
Mixing process:
Firstly, put into sand and fiber. Secondly, put into sand and mix for 2 minutes, make fiber completely open. Thirdly, put into cement and water to mix evenly. The construction can also be carried out according to the normal process sequence, but the mixing time shall not be less than 4 minutes, and the vibration time shall be appropriately extended to make the fiber fully mixed.
Application:
PP Twisted Fiber is widely used in various construction applications such as pavements, bridges, tunnels, and buildings. It can also be used in precast concrete products such as pipes and poles.
Storage:
PP Twisted Fiber should be stored in a dry and ventilated area away from direct sunlight. It should also be kept away from sources of heat and moisture.
