What is oligomeric triazine HALS and how does it compare across HALS grades?
This HALS (CAS 192268-64-7) is a high-molecular-weight oligomeric triazine-piperidine hindered-amine light stabilizer. Its oligomeric structure balances the mobility of monomeric grades with the permanence of polymeric grades, giving durable light protection with good extraction resistance. Bulk quantities are sourced to specification.
- ▸ High-molecular-weight polymeric HALS for long-term light stabilization of polyolefin films, tapes and fibers
- ▸ Low-volatility, extraction-resistant protection suited to agricultural and packaging films
- ▸ Weathering protection of PP/PE, PA, TPE and PU articles

How to choose: HALS are 2,2,6,6-tetramethylpiperidine radical scavengers that regenerate to protect polymers and coatings from UV and thermal oxidation. They are grouped by molecular weight and structure, which sets mobility versus permanence: monomeric grades diffuse quickly for fast protection but migrate and extract more readily; oligomeric and polymeric grades resist volatilization and extraction for long-term durability in thick sections and demanding outdoor exposure. The N-alkoxy NOR-HALS grade carries lower basicity, improving compatibility with acid-cure coatings and flame-retarded or agrochemical-exposed systems where basic HALS can be neutralized.

This triazine HALS is a high-molecular-weight oligomeric hindered amine light stabilizer combining excellent permanence with high efficiency in polyolefins and films. Identity: CAS 192268-64-7.
What it is
This light stabilizer (CAS 192268-64-7) is an oligomeric aminoether/triazine-piperidine. Its high molecular weight gives non-volatility and migration resistance while delivering very high stabilizing efficiency per unit weight.
How it protects against UV
It scavenges UV-generated radicals through the regenerated nitroxyl cycle. The oligomeric structure balances permanence with mobility, so it performs strongly in thin films and demanding outdoor parts.
Applications
This triazine HALS is used in polyolefin films, fibers, tapes and outdoor parts where high efficiency and permanence are both needed, with a UV absorber. Compare polymeric triazine-piperidine HALS and polymeric succinate-piperidine HALS.
Forms, grades and handling
This stabilizer is supplied as a polymeric powder/granule in bags and bulk. Properties are typical reference values; the Certificate of Analysis (CoA) for the lot you buy governs. Handle per the current Safety Data Sheet (SDS); each lot ships with CoA, TDS and SDS.
