High-Performance Mica Rolls

Core Features

• Exceptional Fire Resistance: Acts as a reliable fire-proof layer in battery cells and cables, preventing thermal runaway and ensuring safety compliance.
• Thermal Insulation up to 1000°C: Effectively isolates heat in industrial kilns and induction furnaces, protecting the outer coil and structural components.
• Superior Flexibility & Tensile Strength: Reinforced with glass fiber or PE film, our mica rolls can be tightly wrapped or bent without cracking or delaminating.
• Efficient Slip Plane Performance: Provides a smooth, low-friction surface in furnace linings to accommodate the thermal expansion of crucible materials.

Technical Specifications

• Material Composition: Phlogopite (Gold) for extreme heat or Muscovite (White) for superior electrical insulation.
• Reinforcement Options: Single/Double-sided glass fiber, calcined mica, or silicone-bonded for enhanced durability.
• Custom Dimensions: Thickness ranging from 0.2mm to 0.8mm; Roll widths and lengths tailored to your specific project needs.

Typical Applications

• Induction Furnaces: Serving as a slip-plane or coil insulation to prevent electrical leakage and heat loss.
• Fire-Resistant Cables: Wrapped around conductors to maintain circuit integrity during emergency fire conditions.
• EV Battery Packs: Used as flame-retardant insulation between battery cells or modules to delay thermal spread.

Technical Specifications of Mica Rolls

Our mica rolls are flexible insulation materials made of high-quality mica paper bonded to reinforcing materials (like glass fiber or film) with high-temperature resistant resin.
