High-Strength PVA Fiber For Cement Boards and Concrete Crack Control

PVA Fiber, also known as Polyvinyl Alcohol Fiber, is a high-performance reinforcing fiber mainly used in sheet materials, section materials, mortar, and concrete systems. It helps reduce micro-cracks in concrete caused by plastic shrinkage and improves the toughness, anti-crack performance, and long-term durability of cement-based materials.

As an environmentally friendly fiber material, PVA Fiber is gradually replacing asbestos in many building material applications. With excellent bonding performance in concrete and mortar, polyvinyl alcohol fiber can help enhance crack resistance, impact resistance, anti-infiltration performance, and overall structural stability.

As a professional PVA fiber supplier, we provide stable-quality products suitable for construction boards, insulation boards, concrete components, sprayed concrete, tunnels, basements, roofs, and other reinforced building material applications. For different project requirements, we can recommend suitable grades and provide a competitive PVA fiber price based on application, specification, and order quantity.

Key Benefits

Key Benefits of PVA Fiber

Anti-crack and anti-infiltration: The fibers distribute in mortar or concrete in different directions, which could prevent the appearance and development of crack.

Anti-impact and anti-shock: Absorb impact power and improve anti-impact capacity

Anti-frost and anti-fatigue: Relieve temperature stress, increase anti-frost and anti-fatigue capacity

Anti-rub: Decrease dusting, flaking, weathering of concrete roads.

Increase toughness: Improve brittleness of concrete and increase anti-break capacity.

Weight reduction: Increase anti-stretch and anti-cut capacity of concrete, so the cross section size of ready-made sections are decreased, then decrease weight
