Halogen-free intumescent system reaching UL94 V-0 at 1.6 mm in homo PP, subject to trial.
Typical values for the standard version. Tolerances and test methods are listed in the TDS.
An APP-based intumescent package that chars instead of dripping. No halogen, no antimony, low smoke density. Formulated for PP homopolymer and copolymer used in conduit, housings and cable compounds.
| System | Halogen-free intumescent |
| Typical dose | 4 – 8 % standard · 16 – 20 % high-concentration |
| LOI | ≥ 28 % |
| UL94 rating | V-0 at 1.6 mm — subject to trial |
| Smoke density | Low, no halogen acid |
| Carrier | PP / PE / EVA |
Typical values, for reference only — not a specification and not part of any contract. What binds us is the specification confirmed in writing on your order, and where a sample has been approved, that sample governs. Send us your resin, process and target value and we will confirm the exact figure before you set a production parameter.
Common to every grade we make. Where a grade differs — active content, carrier, colour — the difference is stated on its own data sheet.
| Appearance | Free-flowing pellets |
| Active content | 15 – 30 % (grade dependent) |
| Moisture | ≤ 0.10 % |
| Volatiles | ≤ 0.30 % |
| Agglomerates | ≤ 3 per 1,000 g |
| Heat stability | Grade dependent — see grade data sheet |
| Bulk density | 0.55 – 0.75 g/cm³ |
| Packing | 20 kg PE bag · 25 kg on selected grades |
| Shelf life | 12 months, sealed and dry |
The table above describes the grade family. The figures for your lot are on the COA that travels with it, and the release value is measured on that batch.
If your part is not listed, send a drawing or a photo — we have probably run something close.
V-0 without halogen, low smoke in a fire.
Keeps colour stability at 220 °C.
Passes IEC 60332-1 vertical burn.
Grade documents are issued per grade and travel with the lot. ISO 9001 / ISO 14001 are held by our production site, not by the grade.
FOB Ningbo to any port. We can book the vessel and handle the documents if you prefer.
No. The char former and acid source are in the same pellet. Adding a separate synergist usually hurts the balance.
It is a typical result in homo PP at 1.6 mm, not a certificate. UL94 depends on your section thickness, colour and processing, so we confirm it on a trial lot before you set the specification.
