Chemical Resistance

Vectran fiber is resistant to organic solvents, some acids of >90% concentration, and bases of <30% concentration. Chemical resistance is important in protective apparel use, garment care, and upkeep. The superior bleach resistance of Vectran (shown below at two concentrations) and dimensional and chemical stability simplify garment care.
