Light Diffusion Masterbatch is a functional plastic additive, which is mainly used to improve the optical properties of plastic products, so that it has the effect of uniform Light transmission and soft scattering. It is widely used in LED lampshades, lamp tubes, display screens, packaging materials, automobile industry and other fields, so that the incident light of products is refracted and scattered multiple times, thus eliminating glare, reducing light spots and achieving soft and uniform light transmission effect.

I. Core Functions

• Uniform light transmission: Reduces the harsh feeling of point light sources (e.g. LED).

• Atomization effect: enhances the translucent texture of the plastic surface.

• Improve light efficiency: Optimize light utilization of lamps.

II. Main  Application Areas

(1) LED Lighting

• Lamp shade, lamp tube: Reduce the harsh feeling of LED point light source and make the light softer.

• Panel light: Improve backlight uniformity and avoid ""hot spot"" phenomenon.

(2) Electronic display

• Light guide plate (LCD TV, monitor): Optimize backlight uniformity.

• Touch Screen: Reduces reflections and improves visibility.

(3) Packaging and decoration

• Cosmetic Bottle: Creates a frosted matte finish.

Decorative panels, daylighting panels: Enhance the softness of light transmission.

IV. Key Characteristics

• Controllable light transmittance (usually 60% ~90%).

• High temperature resistance (PC substrate can reach above 300℃).

• Low yellowing (suitable for long-term light environments).

• Easy to process (direct injection molding, extrusion).
