Rubber Grade Mica Powder

Synthetic

In the application of rubber field, mica mainly takes advantage of  two-dimensional structure of mica itself, which provides excellent reinforcing effect for rubber products. Natural excellent insulation properties, provide  good electrical insulation performance for high insulation rubber. Using the barrier advantage of mica  sheet,   it increase the air tightness ; It can partly replace silica  ,what  provides  one  economic solutions for rubber composite materials  ;Excellent shear resistance and abrasion resistance, improves the durable abrasion resistance of high abrasion resistant rubber. Smooth and excellent interface effect provides good isolation characteristics for moulds.

HUAJING synthetic mica series product adopts the principle of melting crystallization in high temperature. According to natural mica’s chemical composition and inner structure, produced after heat electrolysis and melting in high temperature, cooling and crystallization, then the synthetic mica can be got. This product has the advantages of high whiteness purity and ransparence,super low iron content, no heavy metals,heat-resistant,acid resistant alkali resistant, and also it resistant to corrosion of noxious gas, stable performance and good insulation .

Main Property Difference Between Synthetic Mica And Natural Mica

1. Synthetic mica does not contain hydroxyl (OH) -, and its high temperature resistance and thermal stability are higher than that of natural mica, and the service temperature is about 1100 ℃. The fluorophlogopite decomposes slowly above 1200 ℃, and the melting temperature of fluorophlogopite is about 1375 ±5 ℃. The highest use temperature of natural mica: Muscovite 550 ℃; Muscovite 800 ℃ (natural Muscovite begins to decompose at 450 ℃ and almost completely at 900 ℃; Muscovite begins to decompose at 750 ℃, with significant weight loss above 900 ℃). Mica types can be distinguished by high temperature heating or differential thermal analysis.

2. Synthetic mica has less pure impurities and good transparency. Except that its hardness is slightly higher than that of natural mica, other mechanical properties, electrical insulation and vacuum outgassing properties of synthetic mica are better than those of natural mica. Synthetic mica can completely replace natural mica and is a new type of high temperature resistant insulating material with special and excellent properties.
