PVA Fibers in Concrete - WOTAIchem

WOTAIchem is a professional PVA fiber supplier in China. We’ve been manufacturing PVA fibers for the construction industry for many years.


Our high-strength PVA fibers can be used in various application scenarios. They are made of high-quality materials designed to last in even the most demanding environments.


WOTAIchem PVA Fiber For Concrete

Reinforcing concrete with PVA fibers is a fairly new technology becoming more popular as the benefits are becoming more widely known. PVA fibers are used to reinforce concrete in a wide variety of applications, including construction, transportation, and infrastructure.


PVA fibers from WOTAIchem are becoming more popular due to their exceptional strength and durability. They are also resistant to UV light, making them ideal for outdoor applications.

PVA Fiber Properties and Applications

WOTAIchem polyvinyl alcohol (PVA) are monofilament fibers dispersed throughout the concrete matrix. They create a multi-directional fiber network. The network provides shrinkage control, abrasion resistance, and thermal expansion and contraction protection.


Our PVA fibers are added to the concrete mix to improve the overall performance of the concrete. Our fibers are used in various applications, including sidewalks, driveways, and commercial buildings.

If you are looking for a reinforcing solution that is both strong and long-lasting, WOTAIchem PVA fibers are a great option to consider!

PVA fiber enhances caulk and sealant performance. It reinforces bonds, reduces cracking, and ensures long-lasting seals. Making it ideal for airtight and watertight applications.
In joint compounds, PVA fiber adds strength and reduces shrinkage. Resulting in smooth and crack-free surfaces. And achieve seamless finishes with improved durability.
WOTAIchem PVA fiber fortifies grouts and mortars, enhancing their flexural and tensile strength. Say goodbye to cracks and fractures, ensuring sturdy, lasting structures.

3 Most Popular Applications for PVA fibers

WOTAIchem PVA fiber for cement provide shrinkage control, abrasion resistance, thermal expansion, and contraction protection. Our polyvinyl alcohol fibers are important in infrastructure and construction projects where concrete is used.

Other Ingredients to Complete Your PVA Concrete Reinforcement

For more than two decades, WOTAIchem has proudly served as one of the leading water soluble PVA fiber suppliers in China. Our PVA fibers can be incorporated into concrete mixes during or after the batching of other ingredients. Mixing PVA fibers for a minimum of five minutes at high speed is best.


Furthermore, no mix design or application changes are necessary when using either normal or high dosage rates.


It is recommended that a water reducer or superplasticizer (SM or PCE) be used with this fiber when increased workability and finish ability are desired.

Have any questions? We are always here to help you.

Why should I go for WOTAIchem PVA fibers instead of other brands?

WOTAIchem PVA fibers have been designed for maximum efficiency. They can be added directly to the mixing system during or after batching and are mixed at high speed for a minimum of five minutes.


Further mixing does not adversely affect fiber distribution and overall performance. Adding a water reducer or super-plasticizer is often recommended for concrete products that need improved workability and finish ability. WOTAIchem PVA fibers are perfect for your construction projects!

Why is PVA soluble in water?

WOTAIchem PVA is an organic molecule that contains many hydroxyl groups, is very soluble in water due to the strong hydrogen bonding interactions between the hydroxyl groups and water molecules.

What is PVA fiber?

PVA fibers are superior for providing concrete with durable, long-lasting reinforcement and protection. By dispersing throughout the concrete matrix, these monofilament fibers create a multidirectional fiber network that helps regulate shrinkage, prevents abrasion damage, and shields it from thermal expansion and contraction. Invest in PVA fibers for reliable protection against damaging effects.

Is PVA plastic safe?

The EPA and businesses involved in the manufacture and sale of PVA/PVOH have declared this material safe. This conclusion is based on its biodegradability and the minimal effects it has on human health.
