Polyvinyl Alcohol Fiber (PVA Fiber)

Polyvinyl Alcohol Fiber, or PVA fiber, stands out as a top-tier reinforcement for concrete and mortar applications, delivering practical advantages for construction projects.

Product Description

tensile strength

1200 MPa

Elastic modulus









PVA fiber brings a set of impressive qualities to the table. Its remarkable resistance to cracks, high elastic modulus, and superior tensile strength make it a dependable choice for enhancing the performance of concrete. Notably, its molecular bonding with concrete surpasses other fibers by a whopping 300%, ensuring a robust and durable structure.


Tailored for concrete use, PVA fiber addresses common challenges such as plastic shrinkage and thermal cracking. It complies with the standards set by ASTM C-1116 Section 2, reflecting its commitment to quality and reliability.


What sets PVA fiber apart is its inconspicuous integration into concrete. It disperses uniformly throughout the mix, becoming virtually invisible on the finished surface. This makes it an ideal choice whether you're molding concrete or aiming for a polished finish.


Flexibility is another standout feature. PVA-reinforced concrete exhibits significant bending before potential fracture, providing a controlled and resilient response. While it may not always outshine other materials in sheer strength, its failure mechanism distinguishes it as a practical alternative.


There's a claim about PVA fibers forming a "chemical bond" with concrete. While we approach this claim with a level of skepticism, if true, it could represent a significant advantage. If not, the numerous other benefits still position PVA fiber as a reliable and effective choice for construction applications.


In essence, PVA fiber is a versatile and high-performance solution, excelling in addressing common construction challenges while offering enhanced durability and flexibility for a wide range of projects.

Advantages of PVA Fiber:

Anti-Crack and Anti-Seepage:
Fibers are dispersed randomly in concrete, effectively preventing the occurrence and development of cracks. This enhances the waterproof and impermeable properties of the concrete.

Impact Resistance and Seismic Resistance:
PVA fibers efficiently absorb impact energy, contributing to improved seismic resistance in concrete structures.

Frost Resistance and Fatigue Resistance:
The presence of fibers helps manage stress caused by temperature differences, thereby enhancing both frost and fatigue resistance in the material.

PVA fibers play a role in reducing dust, peeling, and weathering on concrete surface layers, particularly beneficial for road surfaces.

Increased Toughness:
By improving the brittleness of concrete, PVA fibers enhance its impact and bending resistance, making it tougher and more durable.

Weight Reduction:
The enhanced tensile (shear) strength of concrete, thanks to PVA fibers, allows for a reduction in the cross-sectional size of prefabricated or poured components, leading to a decrease in overall weight.


Applications of PVA Fiber:

Mass Concrete Pouring:
Ideal for projects involving large-scale concrete pouring, such as piers, high-rise building conversion beams, columns, and floors.

Roof Treatment, Basement, and Wall Plastering Mortar:
Suitable for industrial and civil buildings, PVA fiber is effective in roof treatments, basement construction, and wall plastering mortar applications.

Roads and Bridges:
Used in the construction of pavements and guardrails for roads and bridges, enhancing the durability of these structures.

Dam Construction, Pools, Parking Lots, Sports Fields:
Applied in concrete pouring for dams, pools, parking lots, sports fields, and other large-scale projects.

Concrete Component Production:
Utilized in the manufacturing of concrete components, pipes, and plates, ensuring strength and durability.

Spraying Concrete:
PVA fiber finds application in spraying concrete for tunnels, mines, culverts, slope surfaces, and similar projects.

Challenging Environments:
Suitable for coastal mudflats, saline-alkali areas, and sites prone to chemical corrosion.

Asbestos Replacement:
Can replace asbestos and be used in the production of asbestos cement products.

Building Materials Production:
Employed in the production of lightweight wall panels, GRC panels, insulation boards, and various other building materials, showcasing its versatility.
