Application |
1. TN & STN Mixed Liquid Crystal Monomer： It is a positive dielectric cyanobiphenyl ester liquid crystal monomer with trans cyclohexane rigid structure. It can raise the clearing point, adjust dielectric anisotropy and reduce rotational viscosity, effectively accelerating the electro-optic response of TN and STN liquid crystal mixtures. 2.Low-temperature Crystallization Inhibitor Used as an important blending material for industrial and automotive display liquid crystals. It extends the liquid crystal phase temperature range and prevents crystal precipitation at low temperatures, maintaining stable display effect of instrument panels and small LCD modules in cold environments. 3.Reactive Mesogen (RM) Synthetic Intermediate： The rigid biphenyl mesogenic structure endows the molecule with good ordered orientation. It is a key raw material for ester-based reactive mesogens, applied to produce UV curable liquid crystal polymers and anisotropic optical retardation films. |
