Polyvinyl Alcohol Fiber for Concrete

Polyvinyl alcohol (PVA) fibers, also known as PVA fibers, are a type of synthetic fiber made from high-polymerized PVA using advanced processing techniques. They are characterized by high strength and modulus, low elongation, good wear resistance, and excellent resistance to acids and alkalis, as well as good weather resistance. PVA fibers have good affinity and bonding properties with materials like cement and gypsum, are non-toxic, environmentally friendly, and do not harm human skin. They are one of the green building materials of the new generation of high technology. The raw material for producing PVA fibers is a water-soluble high polymer, with properties between plastics and rubbers, and has a wide range of applications. PVA-formaldehyde fibers can be used in the industrial field for making canvas, waterproof fabrics, filter fabrics, conveyor belts, packaging materials, work clothes, fishing nets, and cables for marine operations. High-strength, high-modulus filaments can be used as the skeletal material for conveyor belts, as lining materials for various hoses, rubber sheets, and rubber shoes, and can also be used to make bicycle tire cord. Due to their resistance to alkalinity in cement and good bonding and affinity with cement, these fibers can replace asbestos as reinforcing materials for cement products.
