HOFNIL-38C: halogen-free flame retardant for polyolefins
HOFNIL-38C is a halogen-free flame retardant additive made by SK Minerals & Additives Ltd., manufacturer in India. Engineered for polypropylene (PP) and polyethylene (PE), it uses a phosphorus-nitrogen intumescent mechanism and is designed to reach UL 94 V-2 at optimised dosages, for compounders and masterbatch makers in wire and cable, automotive plastics and electrical housings.

What HOFNIL-38C is
HOFNIL-38C gives polyolefins reliable fire protection without the drawbacks of halogenated systems.
Compared with conventional ammonium polyphosphate (APP) blends it has higher decomposition stability, better water resistance and superior compatibility with thermoplastic compounding.

Key advantages
- High efficiency in polyolefins: flame retardant performance in PP and PE at optimised dosage.
- Thermal stability: a higher decomposition temperature than uncoated APP, for reliable processing.
- Water resistance: low solubility improves long-term performance in humid conditions.
- Non-halogenated and ATO-free: a safer alternative to halogenated and antimony trioxide systems.
- Low smoke: intumescent char suppresses smoke and toxic gas.
- Processing flexibility: suitable for compound and masterbatch production.
Typical applications
Polypropylene
Compounds, automotive parts and moulded enclosures: UL 94 V-2 at recommended loadings.
Polyethylene
Cable insulation, packaging films and profiles: stable charring and reduced smoke.
HIPS and ABS
A secondary use, in electrical housings and appliance casings, in place of halogenated flame retardants.
