Description

Light stabilizer 944, also known as tinuvin 944, is a polymerized, high molecular weight, highly efficient hindered amine light stabilizer. Due to its multiple functional groups in the molecule, it has high light stability. Due to its large molecular weight, light stabilizer 944 has the characteristics of heat resistance, low volatility and migration resistance, and good resin compatibility. It has a synergistic effect when used together with antioxidants and ultraviolet absorbers. Light stabilizer 944 can be applied to polyolefin plastics (such as PP, PE) and olefin copolymers (such as EVA and a mixture of propylene and rubber, etc.), and its excellent effect can be shown in cross-linked polyethylene. In addition to polyolefin plastics, it can also be used in PPE, POM, PA, PU, soft and hard PVC and PVC blends. In addition, Light stabilizer 944 also has good effects on styrene, rubber and adhesives. Due to the special structure of the polymer, its average molecular weight can reach 3000, so it can be used in systems that require low volatility and migration resistance, especially suitable for films and fibers. In thick sections, light stabilizer 944 is particularly suitable for polyethylene products. At the same time, it also has the effect of an antioxidant, has a long-term thermal stabilization effect on the polymer, and can effectively extend the service life of the polymer.

Precautions

Some sulfur- or halogen-based stabilizers, pesticides and flame retardants may cause side reactions with light stabilizer 944, affecting the use effect. If it is used together with this kind of substance, in order to ensure the effect, it is recommended to conduct a small test first.
