What Are Mica Sheets?
Bonding layers of mica paper manufactures mica sheets with resin to create rigid or flexible boards. This process results in a reliable, durable, and electrically insulating material. Mica sheets are available in a wide range of thicknesses, from ultra-thin 0.1mm sheets for delicate electronics to 50mm sheets for robust insulation.
Sheets are supplied in generous sizes of up to 1000 x 1200 mm, suitable for both small-scale projects and large industrial applications. At ASG, we can convert Mica sheets into finished components, including washers, gaskets, pads, or strips, ensuring precision and convenience for your applications. Laminated options with foils or self-adhesive facings are also available.
Why Use Mica Sheets?
Mica sheets provide critical electrical insulation while offering thermal resistance, flame retardancy, and mechanical strength. These features make them ideal for applications in various industries, including transportation, electronics, construction, and fire safety.
- Restrict the flow of electrical current.t
- Protect electrical conductors from accidental contact.t
- Provide thermal insulation in high-temperature environments.
- Offer mechanical support for electrical and industrial components.
Mica sheets are also easy to cut into small components such as washers, gaskets, or strips, giving flexibility and convenience for bespoke applications.
