2,2,6,6-Tetramethyl-4-piperidinyl stearate（Cat No.:M038913） is a chemical compound that belongs to the class of light stabilizers, specifically HALS (Hindered Amine Light Stabilizers). This molecule features a piperidine ring substituted with four methyl groups and an ester linkage to a long-chain stearic acid, enhancing its lipophilicity and compatibility with various polymers. It is primarily used in the plastics industry to prevent degradation caused by exposure to UV light. The stabilizer works by scavenging free radicals formed during photo-oxidation, thus protecting polymer backbones from breakdown and prolonging the material’s life and aesthetic appearance in outdoor applications.
