Composite Material Advantage

A Ceramic Fiber + Mica Composite Where 1 + 1 > 2

Each material alone has limitations. Ceramic fiber offers great thermal performance but limited dielectric strength. Mica provides superior insulation but insufficient high-temperature endurance on its own. Our composite solves both problems simultaneously — delivering an integrated "thermal + electrical" insulation solution unmatched by single-material products.

Core Features

Five Performance Properties That Matter

Engineered for the most demanding industrial high-temperature environments. Every property verified per batch in our QC laboratory.

◆ 01

Outstanding High-Temperature Resistance

Withstands 600-1000°C continuous service (grade dependent), with short-term peaks up to 1200°C. Maintains structural integrity under direct flame or high-temperature radiation — no melting, no shedding.

◆ 02

Excellent Electrical Insulation

Breakdown voltage 20-50 kV/mm with insulation resistance ≥10¹⁴ Ω·cm — meets the insulation requirements of high-voltage electrical equipment, effectively reducing leakage risk.

◆ 03

Good Flexibility & Workability

Roll format is flexible and can be cut, bent, and wrapped according to actual needs. Easily conforms to irregular equipment surfaces — pipes, kiln walls, motor coils — with high installation efficiency.

◆ 04

Low Thermal Conductivity & Energy Savings

Thermal conductivity ≤0.12 W/(m·K) at 25°C — significantly reduces heat transfer, cuts equipment energy consumption, and improves the thermal efficiency of high-temperature systems.

◆ 05

Weather & Corrosion Resistance

Good resistance to most acids, alkalis, oils, and organic solvents. Not prone to moisture absorption or aging. Service life extends 30%+ beyond traditional insulation materials.

◆ 06

Lightweight Design

Density just 0.3-0.6 g/cm³ — reduces equipment weight, lowers load requirements, and simplifies large-area installation. Ideal for applications where mass savings matter.

Applications

Four Core Industries That Specify This Roll

Wherever high-temperature and electrical insulation must work together in one material, ceramic fiber mica roll delivers.

Industrial Furnaces & Kilns

Primary insulation in high-temperature industrial heating equipment. Reduces heat loss, protects structural components, and seals against thermal leakage.

Furnace interior lining
Furnace door sealing
Flue duct insulation
Kiln wall protection

Electrical Equipment

Insulation gasket material and coil winding wrap for heavy-duty electrical equipment. Improves temperature rating and operational safety of rotating machines and power equipment.

Motor coil wrapping
Transformer insulation
Reactor gasket material
HV switchgear insulation

High-Temperature Piping

Thermal insulation wrap applied to the outer layer of steam and high-temperature air ducting. Acts as both insulation and anti-scalding protection for personnel safety.

Steam pipe wrapping
High-temp air duct insulation
Anti-scalding barrier
Exhaust system insulation

Metallurgy & Heavy Machinery

Thermal insulation layer for steelmaking and casting equipment. Surface protection for high-temperature molds and dies in metallurgical processing lines.

High-temp mold surface protection
Foundry equipment insulation
Heat treatment lines

◆ Why a Composite Roll?

The Integrated "Thermal + Electrical" Insulation Solution

Compared to single ceramic fiber products or pure mica sheets, this composite roll achieves a "1+1>2" performance upgrade. It not only solves the insufficient high-temperature performance of pure mica, but also compensates for the limited dielectric properties of ceramic fiber alone.

With its lightweight design (density just 0.3-0.6 g/cm³), it reduces equipment weight and simplifies handling — making it the ideal choice for an integrated "insulation + electrical protection" solution in demanding industrial high-temperature environments.
