PC particles,light diffusing polycarbonate particles

Light diffusion PC Introduction：
Light diffusing PC is by adding a light diffusing agent to the PC resin. The light diffusing agent is spherical and uniformly dispersed in the PC resin to form a sea-island structure. Because the refractive index of the PC resin and the light diffusing agent are different, the light on the surface of the light diffusing agent is similar to a mirror surface Reflection, after multiple reflections, the light diffusion effect is achieved. The amount of light diffusion agent added, particle size and distribution, and refractive index determine the optical performance of the material. The indicators for evaluating the optical performance of light diffusion materials include total light transmittance and fog Degree and dispersion. The dispersion refers to the angle at which the relative light transmittance is 50%. How to achieve high light transmittance and high haze of astigmatism materials is a difficult point. The light of the fluorescent lamp shines around, from behind The irradiated light returns to the front after being reflected. If the front light exceeds the critical angle, it will be reflected. This light will go through a variety of reflection processes to reach the front again. The other light of the diffuser will be refracted to the inside of the diffuser. After reaching the inside of the diffuser, Meets the diffuser, performs multiple reflections and astigmatism, and maintains a certain brightness on the surface in the process.

The best diffusion rate of light-diffusion PC can reach 99%, uniform dispersion without crystal points, the average light transmittance can reach 86-93%, and the brightness is more than twice that of traditional lampshades. Mainly divided into injection molding grade, extrusion grade, blow molding grade, film grade, frosted grade.

The advantage of light diffusion material is to increase the light diffusion rate and haze of the product under the premise of ensuring high light transmittance. Through the function of the diffusion plate, the entire surface of the board forms a uniform light emitting surface without forming a dark area. Currently light diffusion plate light diffusion plate into PC, PMMA and PS light diffusion plate light diffusion plate. However, PMMA is not scratch resistant, and PS has poor heat and flame resistance. At present, PC materials are used more in LED lampshades.

Application of light diffusion PC plastic：
LED bulb lights, LED fluorescent lights, LED digital tubes, LED tunnel lights, LED street lights, LED ceiling lights, etc.

Features of light diffusion PC plastic:
1. Optical grade PC raw materials with high light transmission, high diffusion, no glare, no light and shadow.
2. Good aging resistance, good flame retardancy and good UV resistance.
3. It can be extruded or injection molded, easy to use and low loss.
4. The light source has excellent concealment and no light spot.
5. Has impact resistance characteristics.
6. Suitable for LED light bulbs, tubes, light-transmitting plates, shells, etc. LED lighting lampshade special light diffusion PC plastic.

Flame-retardant grade light diffusion PC particles are divided into transparent and translucent, and non-flame-retardant grade is translucent.
Flame-retardant grade and non-flame-retardant grade PC particles translucent light diffusion efficiency Our company s existing color plates are used as the standard.

PC particles The quality is divided into A/B/C/ level.

Light diffusion functional master batch is used to add PC PP acrylic particles:

The carrier, pigments and additives of the light diffusion functional masterbatch are all imported high-quality materials, which have been strictly screened and modified and mixed. They have good dispersibility and high temperature processing stability, and can improve the characteristics of crystalline resins.

Light diffusion masterbatch is widely used in various LED lampshades, bulbs, injection molding, extrusion molding, blister molding, etc.

Basic parameters:
Appearance:                               Granule
Temperature resistance:            220-330℃
High temperature volatilization: <0.3%
Adding amount:                           3-10%
Instructions for use: the addition amount should be mixed with the plastic cymbals evenly, and it can be used after drying

Features:
1. Excellent light diffusivity, high light transmittance, good product appearance and gloss.
2. Good diffusivity and haze, good shielding of LED point light sources.
3. Good compatibility with the substrate, good dispersion, no wrinkles, and can give full play to the light diffusion effect.
4. Excellent heat resistance, good thermal stability, suitable for various high temperature processing and forming.
5. No color change, no yellowing, no graying; black spots are not easy to form in the process of processing products, and the yield of good products is high.
6. It has little effect on the physical properties of the resin, so that the product maintains its due physical properties and is very stable.
