Modified insulating mica sheets refer to functional mica insulation materials that have undergone a modification process. This article, compiled by Aochuangte Xin (Nantong) New Energy Technology Co., Ltd., presents the latest 2026 product introduction for modified thermal‑insulating mica sheets, helping industry users gain a clear understanding of this material’s properties and application value.

Core Definition and Principle of Modified Insulating Mica Sheets

The difference between modified insulating mica sheets and ordinary mica sheets

Conventional mica sheets are directly processed from natural mica and inherently possess basic thermal insulation and electrical insulating properties. However, they are relatively brittle, have a high water absorption rate, and tend to degrade in performance when exposed to high-temperature environments over extended periods. In contrast, modified thermal‑insulation mica sheets address these shortcomings by incorporating functional additives and refining the manufacturing process, resulting in markedly improved overall performance. Industry experts widely regard modification as the mainstream approach for upgrading mica‑based thermal insulation materials.

The Core Modification Principle of Modified Insulating Mica Sheets

During processing, modified insulating mica sheets are compounded with silane coupling agents, inorganic high‑temperature‑resistant binders, and other modifying additives. Subsequent high‑temperature, high‑pressure molding densifies the internal structure of the mica sheet and significantly reduces its porosity, thereby enhancing key performance characteristics such as thermal resistance, water resistance, and electrical insulation, making it suitable for a wider range of demanding applications.

Core Technological Advantages of Modified Insulating Mica Sheets

More stable long-term high-temperature resistance

The long-term service temperature of conventional mica sheets typically does not exceed 600°C, whereas specially modified thermal‑insulating mica sheets can withstand long-term operating temperatures of 800–900°C and short-term exposure to temperatures exceeding 1,000°C. They reliably meet the requirements of most high‑temperature applications without exhibiting deformation, decomposition, or other degradation issues.

Superior thermal insulation performance

The modified insulating mica sheet exhibits a denser microstructure, with a thermal conductivity significantly lower than that of conventional mica sheets, resulting in an insulation efficiency improvement of over 30%. Meanwhile, its volume resistivity increases by two orders of magnitude, leading to more stable dielectric properties. Even under humid conditions, it maintains excellent insulation performance, effectively reducing the risk of electrical leakage and enhancing safety.

Application scenarios for different thickness specifications

Aochuangte’s newly developed modified thermal‑insulating mica sheets are available in thicknesses ranging from 0.2 mm to 10 mm. The thinner, modified versions are commonly used for thermal insulation of power‑battery cells and as insulating buffers in electronic components, while the thicker variants are typically employed for sealing industrial kiln doors and providing high‑temperature pipe insulation, among other applications. Custom production is available to meet specific customer requirements.

Main application areas of modified insulating mica sheets

New energy power battery sector

As the new‑energy vehicle industry’s safety requirements for power batteries continue to rise in 2026, modified thermal‑insulating mica sheets—thanks to their excellent thermal and electrical insulation properties—are widely employed as thermal barriers in power battery packs. They can slow down heat propagation during cell thermal runaway, thereby enhancing the overall safety of the battery pack, making them one of the industry’s mainstream thermal‑insulation materials for power batteries today.

Industrial high-temperature equipment sector

In high‑temperature boilers, pipelines, and heating equipment across industries such as metallurgy, chemical processing, and power generation, modified insulating mica sheets serve as thermal‑insulation and sealing materials. They withstand prolonged exposure to elevated temperatures, emit no harmful gases, and offer a service life far exceeding that of conventional insulation materials, helping enterprises reduce equipment maintenance costs.

Key Considerations for Selecting Modified Insulating Mica Sheets

Prioritize verifying the core performance parameters.

When selecting modified insulating mica sheets, first require the supplier to provide test reports issued by an independent, authoritative third-party laboratory. Verify that key parameters—such as temperature resistance, electrical insulation, and water absorption—meet your specific application requirements, thereby preventing the purchase of products that fail to meet performance standards and compromising subsequent operational safety.

Standard Purchasing Procedure Guidelines

  1. Clearly define the temperature resistance, insulation, and dimensional requirements of your specific application, and determine the necessary specification parameters.
  2. Request samples and third-party test reports from suppliers to verify that core performance meets the required standards.
  3. Confirm whether the supplier can provide custom cutting services to meet your production requirements.
