BIOSORB 326
BIOSORB 326 is a strong absorber of ultraviolet radiation in the 300~400nm region and has a high degree of photostability - photochemical energy absorbed in the ultraviolet region is dissipated as thermal energy.
Principally in a greater absorption of longer wavelengths, better compatibility with polyolefins, lower volatility, and suppressed ionization of the phenolic grouping. It is less affected by alkalinity, is less likely to discolor with metals, and has less effect on metal driers and metal catalysts.
It is recommended for use at levels of 0.2~1.0% in PP, PE, Polybutylene, Polyesters, and Coatings.
It can be used in combination with phenolic & phosphite antioxidants, and HALS to optimize performance in outdoor use.
