Lingshou County Huayuan Mica Co., Ltd

Synthetic Mica High temperature insulating materials Synthetic Mica Sheet Product Details Brief Introduction: synthetic mica is produced by hot melting method according to the chemical compositions and inner structures of natural mica. Synthetic mica forms through heating, melting, cooling and crystallization. The raw materials are blended, including quartz sand, potassium carbonate, aluminium oxide, potassium fluosilicate, fused magnesite and some other minerals. It has advantage of smoother surface, higher whiteness and purity. Synthetic mica is free from heavy metals that are harmful to human body.  Chemical Composition: Element SiO₂ Al₂O₃ Fe₂O₃ MgO K₂O CaO F Content（%） 38-43 10-14 0.15-0.3 24-32 9-12 0.2-0.3 8-10 Physical Property: Thermal Endurance（℃） Whiteness Mohs Hardness  Volume Resistivity（Ω.cm） Surface Resistivity（Ω） Dielectric Strength（KV/mm）  Flexural Strength（MPa） Melting Point（℃） 1100-1300 ≥90 3.6 4.5×1015 3×1013 185-238 ≥50 1375 Specification: +4 mesh, -4mesh, 200mesh, 325mesh, 600mesh, 800mesh, 1000mesh, 1250mesh or customize.
