Product Description

Product Description

High-Temperature Mica Board

Our high-temperature mica board is a premium insulation material, designed to perform in extreme temperature and high-voltage environments. Made from high-quality natural mica, it provides excellent thermal resistance, electrical insulation, and compressive strength, making it ideal for both household appliances and industrial equipment. Withstanding temperatures up to 1000℃, our mica boards ensure the durability and safety of your equipment in demanding applications across industries such as metallurgy, chemical processing, and electronics manufacturing.

Exceptional Heat Resistance

Designed for high-temperature applications, our mica boards provide sustained thermal protection. The HP-5 white mica board is suitable for continuous operation at 500℃ and can withstand intermittent use up to 850℃. The HP-8 golden mica board offers even higher resistance, with continuous operation at 850℃ and intermittent use up to 1050℃. This remarkable heat endurance enhances equipment longevity and enables safe operation under extreme conditions.

Outstanding Electrical Insulation

With an electrical breakdown strength of 20 KV/mm, our mica boards provide superior electrical insulation. This ensures safe
operation and protection against risks such as short-circuits and leakage in high-voltage environments, whether used in household
or industrial devices. The robust electrical insulation properties make these boards reliable for applications where electrical
safety is critical.

Environmentally Friendly and Safe

Certified to UL94 with a 94V0 flame rating, our mica boards are flame-resistant, reducing fire risks even in high-temperature applications. Additionally, the material emits minimal smoke (less than 4 seconds) when burned, releasing fewer harmful gases. This makes our mica boards compliant with both environmental and safety standards, ideal for household and industrial applications
alike.

High Compressive Strength and Durability

Engineered for resilience, the mica board boasts a flexural strength exceeding 200 N/mm². Its high-density structure remains stable and strong even under high-pressure, high-temperature environments. This robustness enables our mica boards to endure frequent and intensive industrial usage, offering excellent value and reliability.
