Uses: This product is a hindered amine light stabilizer with a high molecular weight. Due to the presence of multiple functional groups in its molecule, it exhibits high light stabilization performance. Because of its high molecular weight, this product has excellent heat resistance, extraction resistance, lower volatility and migration, and good resin compatibility. This product is mainly used in low-density polyethylene films, polypropylene fibers, polypropylene tapes, EVA films, ABS, polystyrene, and food packaging.
Packaging: 25kg cardboard boxes lined with plastic bags, or as per customer requirements.
Storage: This product should be stored away from light, moisture, and high temperatures during transportation and storage. The integrity of the packaging should be maintained.

This product is a white or pale yellow powder, soluble in organic solvents such as acetone, benzene, and chloroform, with a relative density of 1.01 (20℃) and a weight loss of 1% at 300℃. The effective nitrogen content is 4.6%.
This product is a new generation of polymeric high-molecular-weight hindered amine light stabilizer. It has excellent processing thermal stability, good compatibility with resins, good water extraction resistance, and low volatility and migration. Compared with general low-molecular-weight hindered amine light stabilizers, it has excellent long-term anti-photoaging properties.
This product is an odorless, tasteless, white or slightly yellow powder solid, soluble in organic solvents such as toluene, xylene, chloroform, and tetrahydrofuran, but insoluble in water, methanol, and hexane. It has a softening temperature of 55-85 degrees Celsius, a nitrogen content of approximately 4.9%, and a thermal weight loss starting temperature of 275 degrees Celsius.
