Clariant Exolit AP 740 Flame Retardants

Clariant Exolit AP 740 is a white free-flowing powder Flame Retardants utilizing phosphorus-nitrogen synergistic technology to deliver superior flame retardancy. This halogen-free solution forms an insulating char layer during combustion, effectively blocking heat and oxygen transmission. Specially engineered for thermoset resins, it simultaneously addresses primary fire risks and secondary hazards like smoke emission, making it ideal for applications demanding comprehensive fire protection.

Features Of Clariant Exolit AP 740 Flame Retardants

  1. Dual-Action Protection - P/N synergy enables gas-phase and condensed-phase mechanisms

  2. Intumescent Char Formation - Expands to create 5-10x thicker protective barriers

  3. Halogen-Free Chemistry - Meets IEC 61249-2-21 environmental standards

  4. Low Smoke Generation - Reduces smoke density by 60% vs halogenated alternatives

Typical Applications Of Clariant Exolit AP 740 Flame Retardants

  1. Marine Composites - GRP hulls and decks meeting IMO FTP Code requirements

  2. Mass Transit - Train interior panels compliant with EN 45545-2

  3. Electrical Encapsulation - Transformer resins passing UL 94 V-0 at 3mm

  4. Aerospace Components - Cabin interiors achieving FAA 25.853 standards

  5. Construction Panels - SMC/BMC materials for fire-rated buildings
