Product overview
CHEMGUARD NFF-332 is a 3%x3% alcohol-resistant, non-fluorinated foam concentrate for hydrocarbon and polar-solvent hazards. Its documented scope includes fixed sprinkler systems and Type II and Type III discharge arrangements. The manufacturer identifies an FM 5130 approval package, with acceptance restricted to the proportioning and discharge equipment shown in the applicable approval documentation. Its non-Newtonian viscosity changes with shear, so proportioner selection and calibration are part of the system design. Keep the concentrate within the specified temperature range and select the supplied formulation and packaging region explicitly.

Key features
- Product: NFF-332 3%x3% AR-SFFF concentrate
- Proportioning: 3% on documented hydrocarbon and polar-solvent fuels
- Water supply: Fresh, brackish or salt water within the documented scope
Applications
Documented fixed and semi-fixed foam systems for chemical and petroleum processing, flammable-liquid storage, loading areas and hangars. Confirm the exact fuel, required application density and FM-approved hardware assembly before specification.
Selection and project integration
Provide UDCT with the fuel or test application, required capacity, available water pressure and flow, selected concentrate and compatible equipment. Confirm the exact part numbers, coupling threads, storage conditions and current manufacturer instructions. For foam systems, use the fuel-specific application criteria and approved proportioning/discharge assembly; commissioning must verify the actual hydraulic and proportioning performance.
