- ▸ Long-term light stabilization of polyolefin (PP/PE) films and fibers
- ▸ Low-volatility, extraction-resistant HALS for thin-gauge agricultural and packaging films
- ▸ Weathering protection for TPU, EVA and polyacetal parts
A grade-specific Safety Data Sheet (SDS) — with the complete hazard classification, handling precautions, and transport information — is supplied with every shipment and available on request. Confirm all safety and regulatory details against the SDS for your specific grade.
Request SDS →Like all HALS, it works by scavenging the free radicals generated when a polymer photo-oxidizes, cycling through a regenerating nitroxyl-radical mechanism rather than being consumed, so a small loading protects over a long service life. Because it is polymeric it resists extraction and surface blooming far better than low-molecular-weight stabilizers, which is why formulators reach for it in thin-gauge agricultural and packaging film, tape and fiber where the additive has to stay in place through years of sun exposure. It is typically paired with a UV absorber for surface protection and with antioxidants in polypropylene, polyethylene and related thermoplastics, and is also used to extend the weathering life of TPU, EVA and polyacetal articles
Comparable to Tinuvin 622: RawSource supplies this as an independent equivalent (an offset) to Tinuvin 622 — it is the dimethyl succinate / 4-hydroxy-2,2,6,6-tetramethylpiperidine-ethanol polymer (a polymeric HALS). It is not genuine Tinuvin 622-branded material, and RawSource is not affiliated with, authorized by, or endorsed by BASF.
Tinuvin 622 is a registered trademark of BASF, used here solely for nominative comparison to identify the equivalent grade. RawSource supplies an independent equivalent product; confirm equivalence against your specification and the Certificate of Analysis.
