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.
