Mica rolls are thin sheets of mica that are rolled up into a cylindrical shape. It with longer Length and larger tensile strength than flexible mica sheets. They are made by bonding thin layers of phlogopite mica paper together with a high-temperature silicon resin.
Mica roll usually use glass fiber cloth as reinforce material, which can extend the tensile strength of mica roll. And easier to process to narrow strips or small pieces with good shape and not tear broken. Mica rolls are known for their high electrical and thermal insulation properties, as well as their flexibility and durability.
We sell mica rolls in different sizes: 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.8mm, 1.0mm, 1.5mm, 2.2mm… Width: 1000mm. Length: 25m, 30m, 50m, 100m, 200m…
Application
Mica Roll has excellent electrical and thermal insulation. And combine with glass fiber cloth, that have large tensil-strength. And the rolled long length size are convenient to process and use. The most usage as follows:
1, Slip-Plane: mica with strengthening material, pliable and tough to process to a different shape. Mica rolls can be used as gaskets to seal joints and prevent the leakage of gases or fluids.
2, Safety-Layer: Fire-resistant and protective coil against the refractory material. Mica has a high thermal resistance, making it an effective material for use in high-temperature environments. Mica rolls are often used as thermal insulation in ovens, furnaces, and other heat-generating equipment.
3, Separating-Layer: Barrier and protector. Mica is used in the construction of thermal barriers to prevent the transfer of heat from one surface to another.
4, Isolation-Layer: Electrical and thermal protection. Mica is often used as a sealing material in a variety of industrial applications, including pumps, valves, and compressors.
5, Fastening gasket and washer: Tough and special contraction design for industrial use.
6, Combine with Casi Paper and ceramic mat. For industrial furnaces and customized products.
