UV Stabilizer 770 is a low molecular weight hindered amine light stabilizer (HALS) that provides excellent protection against UV-induced degradation in polymers. It is effective in a variety of polymers, including polypropylene (PP), polyethylene (PE), polystyrene (PS), acrylonitrile butadiene styrene (ABS), and polyurethanes. Its low volatility and high thermal stability make it suitable for applications requiring long-term durability. Also known as Bis(2,2,6,6-tetramethyl-4-piperidyl) sebacate.

It acts as a hindered amine light stabilizer (HALS), protecting polymers from UV-induced degradation.
It is suitable for polyolefins, polyamides, polyesters, polyurethanes, and elastomers.
The concentration typically ranges between 0.1% and 1.0%, depending on the polymer and application.
It absorbs harmful UV rays, protecting coatings from fading, yellowing, and surface degradation over time.
It is FDA-approved for select food-contact applications, but verification with regulations is required.
Yes, it is often blended with antioxidants and UV absorbers for enhanced UV protection and long-term durability.
