  1. Kuralon™ Polyvinyl-alcohol (PVA) CAS # 9002-89-5

  2. Kuralon PVA • Properties • tensile strength (dry) • 48,000-110,000 lb/in^2 • specific gravity: 1.26-1.3 • regain of 4.5-5.0% • absorbency: 12% • shrinkage is 10% @ 215ºC • begins to turn yellow at 220ºC • Melts at 230-235ºC • Does not burn readily

  3. Kuralon PVA • Method of Preperation • vinyl acetate polymerized to polyvinyl acetate • saponified to polyvinyl alcohol • dissolved in H2O and wet spun into an aqueous salt bath • resulting yarn is stretched, heat treated, reacted with formaldehyde to 30% degree of substitution • Availability • continuous multifilament • monofilament • staple fiber • comes in black, blue, or green

  4. Kuralon PVA • Uses • reinforced concrete • tyre cords • filter cloths • nets, ropes, cloths • clothing materials

  5. Kuralon PVA - FRC • Designed for long-term concrete crack control. • 1lb/yard^3 reduces shrinkage cracking +40% after 28 days. • Makes for a 50% improvement when compared to other polypropylene fibers • recomended 1-2lbs/yard to reduce plastic and long term shrinkage.

  6. Kuralon PVA - FRC Current Reports: • reduces concrete cracking by 40% • http://www.allbusiness.com/chemicals/plastics-rubber-industry-resins/5131279-1.html • http://findarticles.com/p/articles/mi_m0EIN/is_2005_Nov_9/ai_n15786264/ • “molecular bonding between the newly engineered fibers and concrete is 300% stronger than that of polypropylene, fiberglass or steel fibers” • http://concreteproducts.com/mag/concrete_bond_strength_improves/
