General Description

Propanedioic acid, (4-methoxyphenyl)methylene-, bis(1,2,2,6,6-pentamethyl-4-piperidinyl) ester, also known as Tinuvin 144, is a UV stabilizer and hindered amine light stabilizer (HALS) commonly used in plastics, coatings, and adhesives. It acts as a free radical scavenger, protecting the material from degradation and discoloration caused by exposure to UV radiation. Specifically, this chemical is effective in preventing the degradation of polymers, such as polypropylene, polyethylene, and polystyrene, making it a valuable additive in the production of various plastic products. Its high thermal stability and excellent compatibility with a wide range of materials make it a popular choice for use in outdoor applications, such as automotive parts and building materials, to prolong the lifespan and maintain the appearance of the products.
