English description(英文原文,共 908 字符)
Product Name:UV Absorber VSU
English Name:UV Absorber VSU
CAS No.:23949-66-8
Aliases:Light stabilizer 312, UV absorber 312, N-(2-Ethoxyphenyl)-N'-(4-ethylphenyl)ethanediamide
Molecular Formula:C18H20N2O3
Physical Properties:Light yellow crystalline powder, odorless, readily soluble in organic solvents such as benzene, toluene, xylene, and ethyl acetate, insoluble in water. Melting point about 124-127°C, good thermal stability, low volatility.
Uses:As a highly effective UV absorber, it is widely used in polymers such as polyamide, polyester, polyurethane, and epoxy resin. It efficiently absorbs UV radiation in the 290-350 nm range, preventing photodegradation and yellowing, and significantly improving the weatherability of products.
Technical Specifications:
Appearance: light yellow crystalline powder
Melting point: 124-127°C
Purity (HPLC) ≥98.0%
Loss on drying ≤0.5%
Ash content ≤0.1%
