PS Diffuser sheet is a sheet produced by extrusion process using polymer material. It is used in displays to diffuse light at a certain angle. The material requirements are high.

The application of PS Diffuser sheet is mainly in two directions: diffuser sheet for backlight module and diffuser sheet for lighting system.

 PS Diffuser sheet for the production of display materials initially PMMA (Plexiglas) and PC-based, because of the large price difference with PS, domestic manufacturers gradually replace the manufacturing of PS diffuser plate, so the field belongs to the PS special material market. PS Diffuser sheet in the entire backlight module accounted for the cost is not high, but its importance is difficult to replace, material performance and Stability affects the display performance and picture quality of LED panels. In the lamp and lighting industry. Customers are generally sensitive to the price of raw materials, and PS Diffuser sheet production factories consider the relatively low price of raw styrene. They adopt a flexible and low price strategy to close to the market price to facilitate the transaction.

Optical grade PS Diffuser sheet to the requirements of light transmission rate of 89% or more, which requires raw styrene purity of 99.7% or more, and does not contain impurities such as polymerization inhibitors. Self-produced styrene can effectively reduce the content of impurities.
