Polypropylene Fiber

PP FIBER

Polypropylene Fiber (PP Fiber) is a synthetic reinforcing fiber designed for concrete, mortar, plaster, screed, and other cement-based construction materials. It is primarily used to control plastic shrinkage cracking and improve the integrity and durability of cementitious systems. By dispersing uniformly throughout the mixture, PP Fiber helps reduce crack formation, improve impact and abrasion resistance, and enhance overall material stability. It provides an easy-to-use and cost-effective reinforcement solution for manufacturers and construction projects requiring improved crack resistance and long-term performance.

Chemical Name: Polypropylene Fiber

Product Advantages

Key Performance

Crack Resistance

Helps control plastic shrinkage and early-age cracking in concrete and mortar, improving the integrity and durability of cement-based materials.

Shrinkage Control

Helps distribute internal stresses caused by plastic shrinkage, reducing the formation and development of shrinkage cracks.

Impact Resistance

Helps improve resistance to impact and mechanical damage, supporting better durability of concrete and mortar during service.

Abrasion Resistance

Helps improve surface resistance to wear and abrasion, making cement-based materials more durable under repeated use and mechanical exposure.

Material Integrity

Forms a three-dimensional fiber network within the cementitious matrix, helping improve cohesion and maintain overall material integrity after cracking begins.
