FR-810A Polymeric Halogen-free Flame Retardant

Key Advantages

Product Description

Tiangang® FR-810A is a novel polymeric NOR halogen-free flame retardant based on hindered amine (HALS) chemistry, combining flame retardancy with light stabilization. It features high resin compatibility, low volatility and low extraction, and is suitable for a wide range of resins including PE, PP, PVC, PA, PMMA, POM, PBT/PET and PC. It is especially suitable for thin applications such as PP fibers, non-woven fabrics and tapes, achieving V1 flame-retardant performance at low dosage while significantly extending outdoor service life.

Features

• Flame retardancy + light stability + long-term thermal stability in a single product
• Polymeric high-molecular-weight structure: low volatility, low migration, low extraction
• Halogen-free, low smoke and low toxicity on combustion
• Resin compatibility; no adverse effect on mechanical properties or appearance
• V1 flame-retardant performance on fibers and non-woven fabrics at low dosage
• Significantly improves outdoor weatherability and service life

Comparison vs BASF Flamestab® NOR 116

Applications

• PP / PE fibers, non-woven fabrics, tapes and raffia
• Transparent PP films and sheets
• Artificial turf, outdoor furniture and sports facilities
• Construction / horticultural textiles, shade nets
• Electrical & electronics housings (PP / ABS compounds)

Recommended Dosage

0.2% – 1.2% (typically 0.8%), depending on resin type, article thickness and required flame-retardant rating. The exact dosage should be determined experimentally.

Frequently asked questions

How is FR-810A different from a conventional halogen-free flame retardant?

Conventional halogen-free FRs — phosphorus and bromine systems in particular — release acidic species during processing or burning, protonating the HALS in the same system and killing light stability. FR-810A is based on polymeric NOP technology, so the FR system itself does not emit those acidic by-products.

Can flame retardancy and weatherability be achieved at the same time?

That is precisely the design goal: flame retardancy, light stability and long-term heat stability in one structure. The achievable FR rating and weatherability must be judged from measured results on the finished part.

What is the processing temperature limit?

Keep processing at or below 250 °C. Above that both flame retardancy and stabilisation can suffer; refer to the table on this page and to measured data.
