Product form: Light yellow powder

Applications

UV Absorber 326 can be widely used in polyolefins (indirectly in contact with food). 326 has low volatility at high temperatures and strong ability to prevent thermal degradation. There is no obvious loss or decomposition during the blending and processing of polyolefins. In the UV protection application of polyester resins, UV Absorber 326 will not react with metal salts to form color stain products during the resin curing process.

Storage

UV Absorber 326 is stable in nature and has no special requirements; pay attention to moisture-proof and avoid high temperature.

Recommended Concentrations

0.1-0.5% (the specific amount to be added is subject to the actual application of the customer).
