UV ABSORBER HOSORB-326 has a wide range of indirect food approvals in polyolefin.
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. It is especially suited for
polyolefins and cold cured polyesters. It protects polymers from UV radiation
helping to preserve the original appearance and physical integrity, especially for
polyolefins and polyester resins.
