For formulation scientists and product developers in the plastics and lighting industries, selecting the optimal light diffusion agent is critical for achieving desired aesthetic and functional outcomes. Silicone-based light diffusion agents, particularly those composed of polymethylsilsesquioxane (PMSQ), have emerged as industry-leading solutions due to their exceptional optical properties and processing advantages. This guide aims to equip formulators with the knowledge needed to make informed purchasing decisions from reputable manufacturers and suppliers, especially those based in China.

A primary consideration when evaluating silicone light diffusers is their particle size distribution. The size of these spherical silicone resin particles directly influences the balance between haze and light transmittance. Smaller particle sizes typically offer higher light transmittance with less haze, making them suitable for applications where clarity is important alongside diffusion. Conversely, larger particles can provide greater haze and diffusion. For instance, in PC applications for LED lighting, a 2-micron particle size might offer the highest light transmittance with reduced haze, while other applications may benefit from different sizes to achieve specific diffusion angles. As a manufacturer, we provide detailed technical data sheets to help you select the ideal particle size for your formulation. We are a prime source for quality silicone light diffusion agents.

Haze and transmittance are the two most critical optical parameters influenced by light diffusion agents. Haze refers to the degree of light scattering, while transmittance measures how much light passes through the material. The goal is often to maximize transmittance while achieving a sufficient level of haze to diffuse light sources effectively and eliminate hot spots. The refractive index mismatch between the silicone spheres and the host polymer matrix is the fundamental principle behind light diffusion. Our silicone light diffusion agents are formulated to provide an optimal refractive index difference, ensuring high diffusion efficiency even at low addition rates. When you buy from us, you can be confident in the consistent optical performance of our materials.

Heat resistance and thermal stability are also vital factors, especially for materials intended for high-temperature processing or applications. Silicone light diffusion agents exhibit superior heat resistance compared to many organic alternatives, maintaining their optical properties and color integrity at elevated temperatures. This makes them ideal for demanding extrusion and injection molding processes commonly used with polymers like PC and PMMA.
