PS diffusion sheets are widely used in various fields due to their excellent light transmittance performance. However, their light transmittance performance is influenced by various factors, including material characteristics, manufacturing processes, and external environments. This article will delve into the key factors affecting the light transmittance of PS diffusion sheets to help understand and optimize their performance.

One of the key factors influencing the light transmittance performance of PS diffusion sheets is their transmittance rate. The higher the transmittance rate, the better the diffusion sheet's ability to transmit light, resulting in brighter illumination.

The quality of the surface of PS diffusion sheets directly affects the scattering effect of light. Rough or uneven surfaces of diffusion sheets may cause uneven light scattering, affecting the illumination effect.

The molding process of PS diffusion sheets has a significant impact on their light transmittance performance. Adopting appropriate molding processes can ensure the smooth and uniform surface of the diffusion sheets, thereby improving light transmittance and light scattering effects.

Different fillers or additives added during the production of PS diffusion sheets can alter their optical properties. By selecting the appropriate additive formula, the light transmittance performance of diffusion sheets can be adjusted to meet different application requirements.

Temperature changes may affect the physical properties of PS diffusion sheets, thereby affecting their light transmittance performance. High temperatures may cause diffusion sheets to soften and deform, reducing light transmittance.

Humidity changes may affect the surface quality of PS diffusion sheets, thereby affecting their light transmittance performance. In high humidity environments, diffusion sheets may develop fogging or water mist on the surface, reducing light transmittance.

The light transmittance performance of PS diffusion sheets is also influenced by the characteristics of the light source. Different types of light sources (such as white LEDs, fluorescent lamps, etc.) produce light with different characteristics, leading to varying requirements for the light transmittance performance of diffusion sheets.

The light transmittance performance of diffusion sheets may vary in different usage environments. For example, when used outdoors, diffusion sheets may be exposed to sunlight, rainwater, and other natural elements, which may affect their long-term light transmittance performance.

The factors affecting the light transmittance of PS diffusion sheets cover multiple aspects, including material characteristics, manufacturing processes, external environments, and usage conditions. Understanding and controlling these factors can help optimize the light transmittance performance of PS diffusion sheets, enhancing their effectiveness in applications such as lighting and decoration.
