What is the oligomeric triazine-piperidine HALS and how does it compare across HALS grades?
This oligomeric hindered-amine light stabilizer (CAS 106990-43-6) is a triazine-linked pentamethylpiperidine oligomer. Its higher molecular weight resists extraction and volatilization far better than monomeric grades (770, 292), while remaining more processable than fully polymeric grades. It combines triazine chemistry with low-basicity N-methyl piperidine groups. Bulk quantities are sourced to specification.
- ▸ High-molecular-weight oligomeric triazine HALS for very long-term UV/light stabilization with minimal migration
- ▸ Light stabilization of PE, EVA, ABS, TPO and engineering thermoplastics in demanding weathering applications
- ▸ Durable protection where low volatility and extraction resistance are required (films, profiles, PVC)

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 (770, 292) diffuse quickly for fast protection but migrate and extract more readily; oligomeric and polymeric grades (2020, 622, 944 and the oligomeric triazine) resist volatilization and extraction for long-term durability in thick sections and demanding outdoor exposure. The N-alkoxy NOR-HALS grade (123) carries lower basicity, improving compatibility with acid-cure coatings and flame-retarded or agrochemical-exposed systems where basic HALS can be neutralized.

This is a high-molecular-weight oligomeric triazine hindered amine light stabilizer — a pentamethylpiperidinyl-triazine oligomer offering very high permanence for demanding polyolefin and film applications, comparable to Chimassorb 119. Identity: CAS 106990-43-6.
What it is
The oligomeric triazine HALS (CAS 106990-43-6) is a large pentamethylpiperidinyl-triazine oligomer. Its very high molecular weight makes it essentially non-volatile and highly resistant to migration and extraction.
How it protects against UV
It scavenges UV-generated radicals through the regenerated nitroxyl cycle. Its size and multiple active piperidine sites give strong, durable protection in thin sections and long-life outdoor parts.
Applications
It is used in polyolefin films, tapes, fibers and demanding outdoor parts needing maximum permanence, with a UV absorber. Compare HALS-944 and HALS-2020.
Forms, grades and handling
It 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. Brand names appear only as nominative cross-references to the generic equivalent we supply — RawSource is not affiliated with those brand owners. Handle per the current Safety Data Sheet (SDS); each lot ships with CoA, TDS and SDS.
