HumenChem Optical encapsulants are transparent materials used to cover and protect LED chips, ensuring optimal light transmission and shielding the components from environmental factors such as moisture, dust, and UV radiation. Silicone materials are commonly used as encapsulants due to their thermal stability, flexibility, and optical clarity. These materials play a critical role in maintaining the efficiency and durability of LEDs, especially in high-power and long-term applications.
