Ls-944 is used in polyolefin plastics (such as PP, PE), olefin copolymers (such as EVA and propylene mixed with rubber, etc.), and in crosslinked polyethylene, it can show its good effect. In addition to polyolefin plastics, it can also be used in polyphenylene ether compound (PPE), polyformaldehyde, polyamide, polyurethane, soft and hard PVC and PVC blends, styrene, rubber and adhesive also have a good effect. Ls-944 is compatible with uv absorbers. Ls-944 can be used in systems that require low volatilization and a small amount of migration. It is particularly suitable for the antioxidant effect of ls-944 in thin films and fibers, as well as the long-term thermal stability effect on polymers.
