Bis(2,2,6,6-tetramethyl-4-piperidyl) sebacatetetrahydrate

Product characteristics are as follows:

1. Effectively absorbs ultraviolet light with wavelengths of 290-400nm, or quenches the energy of excited-state molecules, or has the ability to capture free radicals.
2. Excellent photostability and thermal stability.
3. Good compatibility; does not leach during use.
4. Resistant to hydrolysis, water, and other solvent extraction.
5. Low volatility and minimal pollution.
6. Non-toxic or low-toxicity, inexpensive and readily available.

Applications:
Bis(2,2,6,6-tetramethyl-4-piperidyl) sebacate is suitable for polypropylene, high-density polyethylene, polyurethane, polystyrene, ABS resin, etc. Bis(2,2,6,6-tetramethyl-4-piperidyl) sebacate exhibits superior photostability compared to commonly used photostability stabilizers. When used in combination with antioxidants, it improves heat resistance; it also has a synergistic effect with ultraviolet absorbers, further enhancing photostability.

Applications:
Primarily used as a highly efficient hindered amine light stabilizer, suitable for polypropylene, polyethylene, ABS resin, and polyurethane, etc.

Applications:
Used in unsaturated polypropylene, high-density polyethylene resin, polyurethane, polystyrene, and ABS resin, its light stabilizing effect is superior to currently used light stabilizers.
