LCD Spacer Microspheres


Microspheres maintain a uniform gap between the two glass panels used to form a flat panel display (such as the LCD). Our silicon dioxide spacer is the next-generation highly functional particles which are synthesized from high purity materials that are used in electronic materials.

General Characteristics

Microsphere Composition: 

Silicon Dioxide, amorphous

Nominal Diameter: Density:

4µm, 5µm, 6µm, 7µm, 8µm, 9µm 1.9 - 2.3 g/cm3

Surface Conditions: 

Nonporous, Silanol group

 


Features:
1. Truly spherical, non-agglomerate, particle size is monodispersed.
2. Impurities are very few, no elution of alkaline ions; Uranium, thorium and other
radioactive elements are less than 0.1 ppb.
3. The surface is rich in silanols (≡Si-OH), assuring excellent reaction with silane and
titamate coupling agents. It is also possible to bond functional molecules via surface OH groups as a carrier for synthesizing complex particles.

4.The product is thermally stable. Weight reduction is hardly observed in the temperature range from 200 to 800 ℃. Which is especially suitable for be used in epoxy seals that require high curing temperatures.
