Benzophenone UV absorbers are general purpose UV absorbers commonly used in polyolefin applications and can be incorporated into a range of polymer products. These UV absorbers have good absorption in the wavelength range from 260 to 350 nm and are stable throughout processing.
Benzophenone UV absorbers have excellent compatibility with various resins and are widely used not only as plastic additives but also in applications such as coatings and synthetic resin adhesives.
Benzophenone UV absorbers provide protection for thick and thin sections and are optimized when used in unpigmented or lightly tinted formulations. When used in combination with hindered amine light stabilizers (HALS), the UV protection can be improved, especially when stabilizing thin sections.
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.
Benzophenones are organic compounds that absorb ultraviolet (UV) light. It is used as a photoinitiator in UV curing applications such as printing inks, imaging and clear coatings.
Benzophenones are also used as a screen to prevent damage to cosmetics from UV rays.
Benzophenone UV absorbers enable polymers to retain color, gloss and physical properties under long-term UV exposure. They are effective for short-term exposures.
Benzophenone UV absorbers for polymers have the following advantages:
Cheap price
Simple processing of industrial production
Excellent photostability
Less discoloring
Good water resistance
Benzophenones are also used as additives in plastics, coatings and adhesive formulations.
Benzophenone derivatives, such as benzophenone-2 (BP2) and oxybenzone (benzophenone-3 or BP3), are common ingredients in sunscreens.
