What is diffusion PC plastic?

Photodiffusive PC plastic is a kind of transparent and opaque photodiffusive material particle which is polymerized by a special process with transparent PC (polycarbonate) plastics as the substrate, a certain ratio of light diffusive agent and other additives.

Because the photodiffusive agent is spherical and disperses evenly in PC resin, the island structure is formed. Because the refractive index of PC resin and photodiffusive agent is different, the light on the surface of photodiffusive agent is similar to the mirror reflection. After many reflections, the light diffusive effect is achieved. Optical properties. Optical properties of diffusive materials include all-light transmittance, haze and dispersion. Dispersion is the angle of relative transmittance of 50%. It is difficult to achieve high transmittance and high haze of astigmatic materials. The light of a fluorescent lamp shines around, reflects from the back and goes back to the front and front. The light will be reflected if it exceeds the critical angle. This light returns to the front through a variety of reflective processes. The other light on the diffusion plate will refract into the diffusion plate. When it is inside the diffusion plate, it will meet with the diffuser for multiple reflections and astigmatism, and during this process the surface will maintain a certain brightness.
It is mainly divided into injection molding stage, extrusion stage, blow molding stage, film level and abrasive grade.

Light diffusion PC applications:
LED bulb, LED fluorescent lamp, LED digital tube, LED tunnel lamp, LED street lamp, LED ceiling lamp and so on.
The characteristics of light diffusion plastics are:
Gao Touguang, high diffusion, glare free, optical grade PC raw materials.
It has good aging resistance, good flame retardancy and good UV resistance.
It can be extruded, also can be molded, easy to use and low in loss.
The light source has excellent concealment and no light spot.
It has high impact strength.
It is suitable for LED light bulbs, lamp tubes, light transmittance plates, shells and so on. LED light shade special light diffusion material.
