Benzoxazinone UV Absorbers are powerful UV light absorbers across the broad spectrum UV light, especially for UVA radiation from 320 to 380 nm. Benzoxazinone UV Absorbers are more commonly used in polar polymers such as PET and PC, and are particularly effective in applications such as PET bottles and electronic displays.
Benzoxazinone UV absorbers have high UV absorption capacity and high heat resistance with a TGA (10%) of 371°C, suitable for the most demanding processing environments. Their benzoxazinone UV absorbing ability is much larger than other UV absorbers, and their strong absorbing ability extends to the long wavelength side. These benzoxazinone UV absorbers have excellent heat resistance and can be used in resins that require high processing temperatures.
Since 1989, TINTOLL has actively participated in the development of innovative light stabilizers and application research, and currently has more than 100 specialty products to meet the diverse needs of customers. TINTOLL provides professional formulations for different composite materials. In addition, TINTOLL also provides customers with light stabilizer development services for special applications.
Benzoxazinones are UV absorbers for polymers that absorb broad-spectrum UV rays, especially UVA radiation. They have high UV absorption and are heat resistant. Benzoxazinones are particularly effective against UVA radiation between 320 and 380 nm.
PowerSorb 3638 is a benzoxazinone-type UV absorber that provides strong and broad UV absorption without color contribution; it has high heat resistance, acid and alkali resistance.
