Block Mica is knife-dressed mica with a minimum thickness of 7 mils (0. 18 mm). Block Mica is available in sizes up to 12 to 14 (30 to 35 cm) square. Block Mica larger than this is rare and even it was available it would be far too costly for most applications. Block Mica is available in sheets with an average thickness between 7 mils & 30 mils (0. 1 8 mm & 075 mm) Block Mica is supplied in both natural (random) and calibrated thickness as required by the customer. After splitting into a specified thickness the mica is then cut and punched to the required size and shape to meet the requirements, typically, of an electrical application.
Knife or scissor dressed sheet mica with irregular shape and a minimum thickness of 0.18 mm (0.007 inch or 7 mils) are called Mica Blocks. It is available in sheets with both random (natural) and calibrated thickness as per demand. After undergoing size and quality grading, Mica Blocks are exported. Block Mica larger than this is rare and even it were available it would be far too costly for most applications.

Produced by mechanized or hand setting of overlapping splittings and alternate layers of binders and splittings, built-up mica is used primarily as an electrical insulation material.
Mica is stable when exposed to electricity, light, moisture, and extreme temperatures. It has superior electrical properties as an insulator and as a dielectric, and can support an electrostatic field while dissipating minimal energy in the form of heat; it can be split very thin (0.025 to 0.125 millimeters or thinner) while maintaining its electrical properties, has a high dielectric breakdown, is thermally stable to 500 °C (932 °F).

Mica is a group of silicate minerals commonly used in various industries, including cosmetics and skincare products. Our high-quality, ethically sourced mica offers customizable grades and a radiant shimmer, perfect for enhancing cosmetics, skincare products, and industrial applications, making it an ideal choice for brands seeking both performance and sustainability.
At Johneliz Global Investment Limited, we offer superior-grade Mica, a naturally occurring silicate mineral known for its flexibility, insulating properties, and shimmering appearance. Mica is highly valued in industries such as electronics, cosmetics, construction, and automotive manufacturing. Its ability to resist heat, electricity, and chemical corrosion makes it ideal for use in electrical insulators, capacitors, and thermal insulation. In cosmetics, mica provides a natural sparkle and glow in makeup and skincare products. Our mica is carefully mined and processed to meet industry standards for purity, flake size, and performance. Johneliz Global Investment Limited is committed to delivering consistent quality, tailored specifications, and efficient logistics to support the diverse needs of manufacturers and innovators around the world.
Mica is a hydrated phyllosilicate mineral of aluminium and potassium with formula KAl(F, OH), or (KF) (AlO) (SiO). Muscovite can be cleaved into very thin transparent sheets that can substitute for glass, particularly for high-temperature applications such as industrial furnace or oven windows.
It is also used in the manufacture of a wide variety of electronics and as a filler in paints, plastic, and wallboard. Our monthly supply of these mineral ranges from 1000-2000MT.
