Custom Size Mica Material Sheet Gasket
Mica gasket is based on mica sheet, laminated from mica impregnate with resin, then processing into gasket and various shapes.
Mica is stratiform mineral, its composed of potassium (K), aluminum (AI),magnesium (Mg),Iron(Fe) and lithium(Li).There are different categories of mica, including white mica, phlogopite, biotite and lepidolite (Lithia mica) . White mica is widely used in industry and national defense because it is elasticity, tenacity and insulativity. it is also acid and alkali resistant, and corrosion proof, which can be stripped, with low coefficient of expansion.
