Very low volatility
Stays in thin sections through processing and service.
HALS 119 High-Molecular-Weight Light Stabilizer Supplier
SUNLIGHT® 119 is a high-molecular-weight hindered amine light stabilizer (HALS 119). It gives long outdoor life with very low volatility and extraction in thin PP and PE articles such as tape, fiber and film.
CAS 106990-43-6 · High-MW HALS
Product Overview
HALS 119 has a molecular weight of about 2286, so it does not evaporate during processing or migrate out in use. It is used in PP tape, fiber and film and in other polyolefin articles that need long outdoor life, and it also contributes long-term thermal stability.
Typical specification. Every shipment is supplied with a batch COA; the limits that apply to your order are confirmed in the quotation and contract.
Key Benefits
Long outdoor life
For PP tape, fiber and film exposed outdoors.
Thermal contribution
Adds long-term heat stability in polyolefins.

Technical & Buying Information
Light Stabilizer 119 Buyer Guide
Define the exposure
Note the climate, the expected service life and your weathering test (xenon or QUV hours, retained elongation, gloss or ΔE). For agricultural film, list the pesticides and fumigants the film will meet.
Pick molecular weight for the part
Low-MW HALS move to the surface quickly and suit thick parts; polymeric HALS resist loss from thin films and fibers. Many outdoor packages blend both.
Check interactions
HALS are basic and can interact with acidic additives, halogenated flame retardants, some pigments and sulfur-containing antioxidants. Send your full formulation so we can flag conflicts before the trial.
Lock in supply terms
Agree physical form (powder or granule), packaging, monthly volume and documents up front. A matching CAS number alone does not qualify a new source; run your weathering test and keep the approved lot COA as the reference.

Light Stabilizer 119 FAQ
Is 119 an antioxidant?
No, it is a hindered amine light stabilizer. It also adds long-term thermal stability, but its main job is UV protection.
119 or 944?
Both are high-MW HALS for thin sections. 119 is often chosen for the most demanding tape and fiber applications. Send your current grade for a match.
What dosage is typical?
0.1–0.5% depending on gauge and target life.
Can I get a sample before ordering?
Yes. Tell us the polymer, the test you plan to run and the quantity you need. Samples ship with a COA so you can compare the lot against your current material.
What if a COA does not match our agreed specification?
Send us the agreed specification and the COA showing the difference (parameter, unit and test method). We check it with the production batch record before you accept the material, and replace or re-test where the lot is out of specification.
