Carrier compatibility
HALS plus UV absorber — 1–3 years in agricultural film, 5 years in HDPE pipe, 3–8 years in artificial turf.
Typical values for the standard version. Tolerances and test methods are listed in the TDS.
A balanced HALS and benzotriazole package for parts that live in the sun. Low volatility keeps the additive in the part during a hot, slow extrusion; the absorber protects the surface while HALS protects the bulk.
| System | HALS + benzotriazole UVA |
| Typical dose | 2 – 5 % |
| Outdoor life — film | 1 – 3 years |
| Outdoor life — pipe | up to 5 years |
| Outdoor life — turf | 3 – 8 years |
| Carrier | PE / PP / EVA / PVC |
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.
Retains ≥ 80 % elongation after 5 years outdoor.
Slows yellowing and embrittlement.
3 to 8 years of colour and strength retention.
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.
Yes, but above 80 µm we recommend the higher HALS ratio grade. Tell us the thickness when enquiring.
Some FR systems absorb the UVA. We test the combination before quoting.
Tell us the resin, the process and the target performance. You get a grade recommendation, a landed cost to your port and a sample plan.
