Flame Retardant Additives
(FR Additives)
Flame Retardant (FR) additives are designed to reduce flammability, suppress ignition, control flame spread, and lower smoke generation in polymer systems.
BASIC:
They are essential for enhancing safety and meeting regulatory standards across:
- Electrical & electronics
- Automotive components
- Consumer goods
- Building materials & insulation
- Cable compounds and molded products
APPLICATIONS
- HFFR & LSZH cable jackets
- Electrical housing, switchgear & connectors
- Automotive interiors, exteriors & under-the-hood parts
- Consumer appliances
- Building materials & insulation foams
- Flame-resistant and intumescent coatings
TECHNICAL — Types & Mechanisms
Types
- Halogen-Free Flame Retardants (HFFR)
- Halogenated Flame Retardants (Specialised Applications)
- Intumescent Flame Retardants
Mechanism of Action
- Heat absorption via endothermic fillers
- Char barrier formation for insulation
- Radical quenching to interrupt flame chemistry
- Gas-phase inhibition to reduce fire propagation
- Recommended Use Levels
- Mineral FRs: 20–60%
- Phosphorus-based FRs: 5–20%
- Synergistic packages (ATO etc.): 0.5–5%
