 Application Note: 

 This product is highly efficient UV absorbers, which can effectively absorb the 270-340nm UV, mainly used in PVC, polypropylene, unsaturated resin, polycarbonate, poly methyl benzene acid methyl ester, polyethylene, ABS resin ring epoxy resin, fiber resin. This product almost does not absorb visible light, the initial color of small, especially in transparent products than in the light colored products in more significant stabilizing effect, the product has low volatility, which can effectively prevent loss of processing, in the process of the original nature of the polymer, odor had no effect on the thermoplastic resin has good compatibility, can be evenly mixed in the processing of the products, with excellent heat resistance, in the process does not affect the quality of the products. Proposes to add the amount of 0.1-0.5%. 

 Storage and packaging:
