| Product Name | 2-10 µm Black Polymer-Silica Spacer Microspheres with ≥2000 kgf/mm² Modulus |
| Catalog No. | IGM-HMM-0272 |
| Description | Alta DiagnoTech black spacer microspheres are polymer-silica composite particles with a deep, stable black color. Monodisperse beads combine high mechanical strength with heat, cold and chemical resistance for controlled display-cell spacing. |
| Intended Use | Spacer particles for HTN, STN and FSTN display-cell applications. |
| Principle / Technology | Uniform composite microspheres mechanically control cell gap while providing a black optical background. |
| Performance Range / Specifications | Catalog particle range 2.0-10.0 µm; 4.0 and 6.0 µm are stated as current mass-production sizes; CV ≤3.5%; 10% compression modulus ≥2,000 kgf/mm²; specific gravity 1.8; refractive index 2.42; thermal decomposition temperature >300 °C in air. |
| Product Form | Black polymer-silica composite spacer microspheres |
| Quality Control | Particle-size CV ≤3.5%; particles are described as monodisperse and free from overlap or agglomeration. |
| Key Features | 2.0-10.0 µm catalog range CV ≤3.5% High compression modulus Heat, cold and chemical resistance |
