Applications Features/benefits
|
TINUVIN 326 is especially suited for polyolefins and cold cured polyesters. TINUVIN 326 has a wide range of indirect food approvals in polyolefins. It has a low volatility at high temperatures and high resistance to thermal degradation and can 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, TINUVIN 326 does not form colored complexes with the metallic salts used for the curing process of these resins.

Guidelines for use Polyolefins: It is recommended to use TINUVIN 326 with a HALS type lightstabilizer system for best results. The recommended concentrations range for PP applications from 0.1-0.5%, for PE applications from 0.1% to 0.4%. Polyester resins: The recommended levels for normal polyester resins range from 0.2% to 0.3%, while for chlorinated, flame retardant polyester resins the recommendation is 0.5%.
