It has a low volatility at high temperatures and high resistance to thermal degradation and c therefore be used without significant loss or decomposition in the polyolefin compounding and molding processes. In the use for the UV protection of polyester resins, 5326 does not form colored complexes wit metallic salts used for the curing process of these resins.
