Silicon Mica Sheet

Silicon Mica Sheets, hot-pressed layers of mica paper sheets, a mineral with a laminated structure composed of aluminum, silicon, oxygen, and other elements. The layers are bonded together using specialized silicon/epoxy resins or adhesives. These sheets are known for their high dielectric strength, excellent thermal resistance, and resistance to chemicals, moisture, flames, and hot molten splashes of iron and metals.

Application

Commonly, in foundries, mica sheets are used to insulate and separate components during casting processes. Their ability to withstand the intense heat up to 1200°C of molten metals makes them indispensable for maintaining the integrity of moulds and refractory linings.

Mica sheets also act as heat shields in welding and brazing processes. Their capacity to withstand extreme temperatures protects surrounding components and prevents distortion or damage due to excessive heat exposure.

Availability

Mica Sheets are available with silicon or bonding in muscovite and phlogopite mica to suit different temperature applications, with thickness ranging from 0.5mm to 50mm. Machined components are also available as per the drawing. Deviations in specifications, construction, sizes, or packing can be made upon the customer’s request.

Shelf Life

Mica sheets exhibit a shelf life of 12 months from the date of manufacture when stored at a temperature 25°C and 50 % relative humidity.
