3M FRMB5915 Flame Retardant

3M FRMB5915 Flame Retardant is a high-performance intumescent fire-resistive material from 3M’s Fire Barrier portfolio. It expands when exposed to heat, sealing penetrations in walls and floors to impede flame, smoke, and toxic gas spread. Designed for cable and conduit applications, it meets UL 1479 and ASTM E814 standards, offering reliable passive fire protection in commercial and industrial settings.

Features Of 3M FRMB5915 Flame Retardant

  1. Halogen-free formulation for reduced smoke and toxic gas emission during combustion.

  2. Excellent thermal stability, maintaining performance up to 250 °C in continuous use.

  3. High phosphorus content enabling efficient char formation and flame inhibition.

  4. Good compatibility with engineering thermoplastics including polyamide (PA6, PA66) and polybutylene terephthalate (PBT).

  5. Low volatility and minimal plate-out tendency during high-shear compounding and extrusion.

Typical Applications Of 3M FRMB5915 Flame Retardant

  1. Flame-retardant compounds for automotive interior components (e.g., connectors, housings).

  2. Electrical and electronic enclosures requiring UL 94 V-0 rating at thin wall sections.

  3. Consumer electronics casings where low smoke density and RoHS compliance are critical.

  4. Industrial control system parts exposed to elevated ambient temperatures.

  5. 3D printing filament additives for functional prototypes with enhanced fire safety.
