Light Emitting Diodes (LEDs) are a type of electroluminescent solid-state device. With the continuous innovation of technology and the guidance of national policies, the entire LED product has developed rapidly, The LED packaging industry is growing synchronously. Among packaging materials, organic silicon packaging materials have been recognized by the industry for their excellent performance and have become the fastest developing and most valuable packaging materials, demonstrating enormous market value.
LED organic silicon packaging adhesive is a new type of high-end liquid silicone, also known as optical packaging. It can maintain high transparency in the visible light region, has a high absorption rate of ultraviolet rays, and can improve the light output rate and service life of lighting devices.
In recent years, due to the rapid development of the LED industry, The demand for LED packaging materials is increasing, among which LED silicone packaging adhesive has become a leader in LED packaging materials due to its excellent physical and chemical properties. As the energy crisis intensifies, The LED industry will continue to grow, therefore, The market potential of LED packaging materials is enormous. High power LED packaging materials require their raw materials to have high transmittance and refractive index, and phenyl silicone oil has become an important component of LED packaging adhesive raw materials. As the molar fraction of phenyl increases, the high temperature resistance, radiation resistance, and refractive index of organic silicon materials are all improved, The importance of phenyl silicone oil for LED packaging adhesive is increasing day by day.
The phenyl silicone oil used for LED packaging mainly includes two types: vinyl terminated methyl phenyl silicone oil and phenyl hydrogen containing silicone oil. Phenyl silicone oil can be further divided into low phenyl silicone oil (phenyl molar fraction 5% -10%) based on its phenyl content; Medium phenyl silicone oil (phenyl mole fraction 25%); High phenyl silicone oil (phenyl mole fraction 45%). Different LED packaging adhesives have different requirements for phenyl content. High power LED packaging adhesives generally require a higher phenyl content in order to achieve a high refractive index and reduce the loss of light source energy.
