Mica with release liners refers to mica sheets or tapes backed by a protective release liner. The release liner serves as a protective layer that can be peeled away during application, revealing the adhesive side of the mica. This configuration is particularly advantageous in industrial settings. The release liner streamlines the installation process, allowing for easy handling and precise application of the mica material.
The inclusion of pressure-sensitive tapes further enhances usability by eliminating the need for additional adhesives. This combination of mica with a release liner and pressure-sensitive tapes not only simplifies installation but also ensures a secure and uniform application, facilitating the utilization of mica in various applications, including electrical insulation, gasketing, and heat shielding. Overall, these features contribute to the efficiency and versatility of mica in different industrial contexts.

A protective peel-away layer that covers the adhesive until installation, preventing contamination and unintended bonding.

High-temperature, electrically insulating mica material backed by the PSA.

Silicone-based PSA layer that adheres instantly with light pressure; no heat, water, or solvent activation needed.

The substrate (metal, ceramic, composite, or equipment part) for protection and performance.
Our AX-THERM Muscovite & Phlogopite mica sheets consist of 85-90% high-grade Muscovite or Phlogopite that is impregnated with a high temperature resistant silicone resin.
Mica is a mineral that belongs to a group of silicate minerals known as phyllosilicates. It is characterized by its highly perfect basal cleavage, which allows it to be split into thin sheets that are flexible, elastic, and transparent. Mica is valued for its resistance to heat, electricity, and acids.
Mica is best for applications requiring thermal insulation, electrical insulation, and resistance to chemical corrosion. It is extensively used in the electronics industry for components like capacitors and insulators, and in industries requiring high-temperature insulation materials, such as furnaces and microwave ovens.
In a microwave, a mica sheet is used as a waveguide cover. It covers the aperture through which microwaves are admitted into the main cavity of the oven. The mica sheet helps prevent food particles and moisture from entering the waveguide, which can cause damage and efficiency loss.
Mica sheets are valued for their clear visibility and effective protection from outdoor conditions, effectively blocking dust, dirt, and harsh weather. Their durability against scratches ensures they maintain quality over time, making them a reliable choice for see-through enclosures.
