• Detailed Description:

  Cas No. :459-32-5 Main Application:
  1.Applications in liquid crystal materials
  2.Application for organic synthesis
  3.As food additive.
  
  Applications in liquid crystal materials:
  
  The liquid crystal material for display must satisfy the most basic requirements such as wide operating temperature range, low operating voltage and quick response. Fluorine atom has some special properties such as module effect, electron effect, barrier effect and osmosis effect. Therefore, the introduce of fluorine atom in the liquid crystal material will improve many properties of the liquid crystal.
  
  To fluorine cinnamic acid belongs to fluoride-containing liquid crystal, which is characterized by low limit, low viscosity and excellent permeability. Its resistivity and voltage maintaining rate are very high, the stability is much higher than that of traditional materials. The trans melting point of 249 degree C to 250 degree C, which can satisfy a wide operating temperature range. Due to high photosensitivity and fast photolysis speed which can greatly shorten the response time of the liquid crystal and increase the screen brightness and brightness. Due to the color saturation much higher than traditional materials, it can be widely used in mobile phones,computers and other LCD materials.
  
  In the foreign LCD industry, especially the most advanced TFT LCD enterprises, has gradually replaced the traditional polymer materials with fluorocinnamic acid. By contrast, the response time of a few high-end LCDS can be reduced to 20ms, But for the use of fluorine cinnamic acid liquid crystal material, monitor response time can improve below 16 ms, and from 20 degree C to + 50 degree C temperature range can be used by normal way, after temperature reinforcement of TFT - LCD low working temperature can reach 80 degree C below zero. In addition to the excellent performance of products, due to its easy production, seasy storage, easy transportation, and lower prices, it has been considered as the most advanced LCD, the most excellent and the most popular liquid crystal materials.
