The Flexibility Advantage

Bendable. Wrappable. Foldable.

Unlike rigid mica plates, our flexible grade is engineered to conform to irregular shapes — perfect for wrapping around motor coils, lining curved cable channels, or fitting into tight spaces in aerospace and automotive wire harnesses.

Verified through rigorous flexibility testing: no delamination, no mica slippage, no cracking. The thinnest grades (0.1-0.5mm) offer maximum flexibility for tight winding applications, while 1-2mm grades provide structural insulation with retained bendability.

Key Features

Six Properties That Make It the Coil Engineer's Choice

Every property is verified per batch in our QC laboratory. Full test reports shipped with every order.

◆ 01

Exceptional Flexibility

Can be bent, wrapped, or folded without cracking — perfect for irregular-shaped parts like motor coils, curved cable jackets, and complex wire harness geometries.

◆ 02

Strong Electrical Insulation

Dielectric strength 12-25 kV/mm — suitable for low to medium voltage systems (1 kV-20 kV). Effectively prevents arcing and current leakage in rotating equipment.

◆ 03

High Temperature Resistance

Withstands continuous working temperatures from 300°C to 900°C (depending on mica type). Maintains performance in engine compartments and furnace wiring environments.

◆ 04

Flame Retardant

Classified as self-extinguishing (UL94 V-0 rating). Resists ignition and slows fire spread — enhancing safety in enclosed electrical installations and equipment enclosures.

◆ 05

Lightweight & Thin Profile

Lower density (0.8-1.2 g/cm³) compared to rigid mica plates — 40% weight reduction. Minimizes the volume of insulation components in space-constrained applications.

◆ 06

Moisture & Chemical Resistance

Water-repellent (water absorption ≤1.5%) and resistant to mild oils, acids, and alkalis — ensures durability in humid or industrial environments typical of engine bays and factories.

Dimensions & Format

Wide Size Range for Every Installation Need

From tiny coil wraps to large equipment lining — all available with custom cutting to your exact specifications.

◆ Thickness Range

0.1 – 2 mmThinner grades for tight wrapping

Ultra-thin 0.1-0.5mm grades offer maximum flexibility for tight coil winding. 0.5-2mm grades balance insulation thickness with bendability.

◆ Sheet Dimensions

200×300 to 1000×2000mm · Standard range

Standard sheet sizes from small 200×300mm patches to large-format 1000×2000mm sheets. Custom cutting to project-specific dimensions available.

Customization Options

Reinforcement & Adhesive Choices

Choose the right combination of reinforcement backing and adhesive to match your specific installation requirements.

◆ Option 1 · Reinforcement Backing

Choose Your Structural Reinforcement

Optional backing layer provides mechanical reinforcement depending on whether your application prioritizes strength or maximum bendability.

◆ Type A

Glass Fiber Mesh

Enhanced tear resistance & tensile strength. Best for industrial applications with mechanical stress.

◆ Type B

Organic Film

Enhanced flexibility & conformability. Best for tight coil winding and complex wrapping geometries.

◆ Option 2 · Adhesive System

Compatible with Both Adhesive Types

Our flexible mica plate is compatible with both heat-activated and pressure-sensitive adhesives — giving you installation flexibility on any surface type.

◆ Option A

Heat-Activated

Strong permanent bond after heat activation. For high-reliability long-term installations.

◆ Option B

Pressure-Sensitive

Peel-and-stick convenience for fast installation. Ideal for field service and rework.

Applications

Five Industries Where Flexibility Is Essential

Specified whenever rigid insulation can't conform to the geometry — motors, cables, harnesses, and compact heating equipment.

Motors & Generators

Wrapped around stator and rotor coils to provide insulation while accommodating the movement of rotating parts — the core application for flexible mica.

High-Temperature Cables

Used as a flexible insulation layer in fire-resistant cables — especially those running through curved or narrow spaces in buildings or industrial plants.

Transformers & Reactors

Lined between windings or around wires — conforms to narrow gaps to prevent short circuits in compact transformer and reactor designs.

Aerospace & Automotive Harnesses

Insulates wire harnesses and connectors in engine compartments or tight vehicle bays — where flexibility and heat resistance are both essential.

Industrial Heating Equipment

Wrapped around heating elements or thermocouples to protect nearby parts from radiant heat — while accommodating compact equipment designs.

Custom Die-Cut Shapes

Our factory provides CAD-based precision cutting to your exact component specifications — ready-to-install shapes for OEMs and industrial customers.
