Aramid 9352 (93/5/2 aramid blended)
Aramid 9352 English Translation
Aramid 9352 (also known as 93/5/2 or Aramid 3A) is the most widely used three-component blended ratio for fire-fighting and flame-retardant workwear:
93% Meta-Aramid (1313): Provides inherent flame retardancy, high temperature resistance and heat insulation; no molten drips and non-combustible when exposed to fire.
5% Para-Aramid (1414): Enhances tensile strength, tear resistance and wear resistance; stabilizes fabric structure under combustion.
2% Anti-static Fiber: Eliminates static sparks, suitable for explosion-proof scenarios such as oil & gas, petrochemical and power industries.
