LED Materials

To Upgrade LED Industry by Providing Superior Materials.
To meet the trend of the LED industry, we are importing LED materials, including epoxy resins, hardeners, catalysts and so forth. These products are characterized by their superior heat and UV resistance, gas barrier, and adhesion. They can replace silica gel and become brand new encapsulant materials.
