One PVA fiber is drawn for strength and remains in a cement composite to bridge cracks. Another is designed to dissolve during textile processing. A third is modified for a flame retardant textile application. These grades can share a chemical starting point while serving entirely different jobs. For a concrete producer, the useful question is specific: which PVA grade, at what dosage, in which binder and process, delivers the measured crack response and durability required by the project?
