| Notes |
HS-944 is an oligomeric HALS; it imparts excellent light stability in polyolefin (PP, PE, PVC), PA, polyacetals and polyester. It shows excellent It shows excellent compatibility and high resistance to extraction. When be used with other HALS together shows excellent synergistic effect. In addition, it can be used in food package materials. Now, HS-944 is one of the advanced HALS and is used widely at home and abroad.
