Benzoate UV Absorber

Benzoate UV absorbers can increase the resistance of polyolefins to harmful UV light by scavenging free radicals formed during photo degradation of plastic materials. The use of benzoate UV absorbers together with the hindered amine light stabilizer (HALS) creates a synergistic effect, providing superior performance over HALS alone, especially in polyolefin substrates. The has good compatibility with polyolefin substrates, is resistant to extraction, and can be used in many types of polyolefins.

Since 1989, has actively participated in the development of innovative HALS UV absorbers 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.
