Specification

The preparation of Polymethylsilsesquioxane: Take Methyltrimethoxysilane as raw material, acid as catalyst, firstly hydrolyze reaction, conduct condensation under alkaline conditions, and condense and crystallize into spheres. After high-temperature maturation and other processes, a solid product is finally obtained.

 

XJY-801 Polymethylsilsesquioxane (Spherical Silicone Resin Powder) is widely used in the field of light diffuser material manufacturing.

 

The light refractive index of the spherical silicone resin is different from that of the basic material. Light from a single direction can be diffused into various directions inside the diffusion material with spherical silicone resin.

 

At the same time, it can be used as a wear-resistant modified material. Due to the characteristics of silicone materials, spherical silicone resins also have related applications in personal care.

Application

 

 XJY-801 Polymethylsilsesquioxane (Spherical Silicone Resin Powder) can provide good optical performance balance of transmittance, haze as well as diffusion effect, widely used in high-end transparent PC lamp, lampshade, lightbox, and flat-panel LCD light diffuser plate, etc. 

 

Polymethylsilsesquioxane silicone microspheres are a kind of superfine spherical powder material with organic and inorganic characteristics, three-dimensional network spherical shape. It has good optical properties, dispersion, lubricity, heat resistance, excellent silky feel and so on.

 

1. Light diffusion agent: Used in PC / PP / PMMA / lampshade / Light Box, Flat-panel LCD PS light diffuser, PET light diffusing film.

    In resin processing, Polymethylsilsesquioxane powder silicone light diffusers can be used as light scattering agents to obtain a translucent frosting effect. Compared with inorganic powder, this product has better compatibility with resin and is easier to disperse in resin.

2. Coating: Improve Lubricity, Scratch resistance, Dispersibility and Hydrophobic;

    Polymethylsilsesquioxane powder is suitable for coatings and inks with high heat resistance and solvent resistance and has good toughness and scratch resistance. Compared with inorganic powders, it is easier to disperse, not easy to precipitate, and has better adhesion when combined with coatings. It has a particularly delicate touch and can form a more advanced surface coating.

3. Plastic film: Antisticking agent, Antiblocking agent; Opening agent for polyethylene and polypropylene films

    The spherical appearance of Polymethylsilsesquioxane powder can prevent the film surface from being damaged, its superior light transmission performance can maintain the transparency of the film, prevent particles from falling off the film surface. It has excellent temperature resistance, yellowing resistance and high durability. 

 

Advantages of Polymethylsilsesquioxane

High brightness but less addition, high yield; excellent light diffusivity and high light transmittance; disperse the model in the resin and can be added directly; high-temperature resistance to 470 , no discoloration, yellowing, and ash; black spots are not easy to be generated in the process of extruding the lampshade.

 

  The main influencing factors of Polymethylsilsesquioxane powder use effect

1. Particle size: It is necessary to determine the amount of Polymethylsilsesquioxane powder to be added according to the Polymethylsilsesquioxane with different particle sizes and the changes in haze and light transmittance.

2. Spherical regularity:   The more spherical Polymethylsilsesquioxane light diffusing agent powder particles, the more the light deflects on the surface of the sphere, and the more regular reflection angles. Therefore, the prepared Polymethylsilsesquioxane powder has higher haze and better use effect and lower addition.  

3. The shape of the material itself: The morphology of light diffusion materials is different. Even if the materials may be the same, the addition amount and particle size of Polymethylsilsesquioxane powder are different.

4. The refractive index of the material;

5. Material thickness, etc.;
