On the path toward efficient and environmentally friendly lighting solutions, a low-refractive-index methyl-based LED encapsulant named IOTA LEDL 3220 is quietly reshaping the industry landscape. With its unique performance advantages, this innovative product has become the ideal choice for COB (Chip-On-Board) and integrated LED applications.

The standout feature of IOTA LEDL 3220 is its low refractive index of 1.41. This characteristic effectively reduces photon loss at the interface between the encapsulant and the chip, thereby significantly enhancing the light extraction efficiency of LED light sources. For lighting designers pursuing极致光效, this is undoubtedly a tremendous boon. Additionally, this encapsulant possesses excellent adhesion properties, firmly bonding to PPA and metal materials to ensure LED components remain stable and reliable even in harsh environments.

Beyond its superior optical performance, IOTA LEDL 3220 also excels in physical properties. Its Shore A hardness of 60A is moderate, ensuring structural strength of the encapsulant while facilitating processing and molding. With a high elongation rate of 110% and a tensile strength of 6 MPa, the encapsulant exhibits outstanding impact resistance and fatigue resistance, effectively extending the service life of LED products.

In terms of light transmittance, IOTA LEDL 3220 achieves an impressive 92%, ensuring the purity and brightness of LED light sources. Furthermore, its coefficient of linear expansion of 210 ppm effectively reduces stress within the encapsulant caused by temperature fluctuations, preventing issues such as cracking or delamination.

Regarding the curing process, IOTA LEDL 3220 adopts a two-stage curing method (80°C for 1 hour + 150°C for 3 hours) , which ensures thorough curing of the encapsulant while avoiding potential damage to the LED chip from excessive heat. This design not only improves production efficiency but also guarantees the stability of encapsulation quality.

With its unique optical properties, physical characteristics, and optimized curing process, IOTA LEDL 3220 low-refractive-index methyl-based LED encapsulant offers a brand-new solution for the LED lighting industry. Whether in commercial lighting, residential lighting, or outdoor lighting, it is poised to become the preferred material for designers seeking efficient, environmentally friendly, and reliable lighting solutions.
