Material: Polyvinyl Alcohol (PVA), a synthetic polymer derived from vinyl
acetate.
Appearance: Typically white or slightly translucent fibers.
Tensile Strength: Ranges from 12 cN/dtex to 20 cN/dtex, depending on the grade.
Modulus of Elasticity: High initial modulus, offering excellent stiffness and
load-bearing capacity.
Elongation: Moderate elongation at break, balancing strength and flexibility.
Density: ~1.26–1.29 g/cm³, lighter than steel fibers.
Resistance:
Excellent resistance to alkali, acid, and UV exposure.
High thermal stability under normal usage conditions.
Polymerization: PVA is synthesized and treated to enhance its crystalline
structure.
Wet Spinning: The polymer is dissolved, extruded through spinnerets, and
coagulated into fibers.
Heat Treatment: Fibers undergo stretching and heat setting to improve strength
and modulus.
Surface Treatment: Treated with specific coatings to enhance bonding with other
materials, like concrete or resins.
