Advanced flame retardants:
Where safety meets sustainability
HOFNIL-38C
(Halogen-Free Flame Retardant for Polyolefins)
HOFNIL-38C is an advanced halogen free flame-retardant additive engineered specifically for polypropylene (PP) and polyethylene (PE) systems. Its formulation is based on a phosphorus–nitrogen intumescent mechanism, providing reliable fire protection without the drawbacks of halogenated systems.
Compared with conventional ammonium polyphosphate (APP) blends, HOFNIL-38C delivers higher decomposition stability, improved water resistance, and superior compatibility with thermoplastic compounding. It is designed to achieve UL94 V-2 ratings in polyolefin compounds at optimized dosages, making it a strong choice for wire & cable insulation, automotive plastics, and electrical housings.
Typical Applications
| Polymer / Substrate | Application Areas | Performance Outcome |
|---|---|---|
|
Polypropylene (PP) |
Compounds, automotive parts, moulded enclosures |
UL94 V-2 compliance at recommended loadings |
|
Polyethylene (PE) |
Cable insulation, packaging films, profiles |
Stable charring, reduced smoke emission |
|
HIPS / ABS (secondary use) |
Electrical housings, appliance casings |
Eco-safe replacement for halogenated FRs |
Key Advantages
- High Efficiency in Polyolefins – Delivers flame retardant performance in PP/PE with optimized dosage levels.
- Thermal Stability – Higher decomposition temperature than uncoated APP, ensuring processing reliability.
- Enhanced Water Resistance – Low solubility improves long-term performance under humid conditions.
- Non-halogenated & ATO-free – Safer alternative to conventional halogenated and antimony trioxide systems.
- Low Smoke Emissions – Intumescent char formation suppresses smoke and toxic gas release.
- Processing Flexibility – Suitable for compound and masterbatch production.
