Applications
HS-944 is a polymeric hindered amine light stabilizer that can protect polymer materials from light degradation and thermal degradation caused by ultraviolet light and long-term thermal aging. HS 944 has low volatility, good stability, and good compatibility with substrates. It can be used in materials such as PP, LDPE, HDPE, XPE, EVA, POM, PU, and PVC. Due to the high molecular weight of HS 944, it is particularly suitable for use in film products. HS-944 can be used in combination with phenols, phosphite antioxidants, low molecular weight HALS and ultraviolet absorbers to improve the stability of outdoor products. HS 944 is not recommended for use in combination with sulfur-containing DLTP and DSTP.
Storage
HS-944 is stable in nature and has no special requirements; pay attention to moisture-proof and avoid high temperature.
