71878-19-8
Product Name: Light Stabilizer 944
Englishaliases:1,3,3-tetramethylbutyl)amino)-"poly(6-((;Cr-144;Poly[[6-[(1,1,3,3-tetramethylbutyl)amino]-s-triazine-2,4-diyl]-[(2,2,6,6-tetramethyl-4-piperidyl)imino]-hexChemicalbookamethylene-[(2,2,6,6-tetramethyl-4-piperidyl)imino]];"LS944;poly(6-((1,1,3,3-tetramethylbutyl)amino)-;UV-STABILIZER944;Chimassorb944,Cyasorb3346,Lowilite94
CAS number: 71878-19-8
Molecular formula: C35H69Cl3N8
Appearance: White to pale yellow powder or granules at room temperature
Conventional packaging: 25kg/bag; 50kg/barrel
The light stabilizer TH-944 has low volatility and good stability, which can protect polymer materials from photodegradation and thermal degradation caused by UV irradiation and long-term thermal aging.

1. Plastic industry: core anti-aging additives, suitable for long-term outdoor scenes
2. Coating industry: Improve the weather resistance of coatings, extend the service life of decoration and protection
3. Rubber industry: Enhance weather resistance and ozone resistance, adapt to outdoor seals
4. Fiber and composite materials industry: protecting polymer matrix and maintaining structural stability
Light stabilizer 944 belongs to low toxicity substances, with acute oral toxicity (LD50)>5000mg/kg (rats), no significant irritation upon skin contact (skin irritation test score ≤ 1.0), and inhalation of dust may cause mild respiratory dryness (such as dry throat) in sensitive populations. It is recommended to wear N95 dust masks and nitrile protective gloves when operating industrial grade products to avoid inhaling dust and long-term skin contact; If accidentally inhaled, transfer to a well ventilated area to relieve symptoms; Rinse with clean water after skin contact, no special irritation risk; The product should be kept out of reach of children and the storage area should be labeled as "non food".
It should be stored in a cool, dry, and well ventilated warehouse, avoiding direct sunlight (to prevent UV light from affecting molecular stability). The warehouse temperature should be controlled at 5-30 ℃, away from heat sources (such as heating pipes, boilers, and heating equipment). The warehouse should be equipped with ordinary lighting and ventilation equipment (no explosion-proof type is required), and open flame operations are strictly prohibited (although not flammable, dust accumulation and contact with open flames should be avoided).
During transportation, it is necessary to load and unload gently. When using forklifts or pallets for handling, avoid collisions and squeezing of packaging (especially woven bags and cardboard drums) to prevent dust leakage caused by packaging damage; Wear anti slip gloves and dust masks during manual handling. It is strictly prohibited to throw or roll the packaging to avoid product adhesion and dust inhalation.
