Key Features

Six Properties That Define Our Mica Plate Series

Every plate across all four grades is manufactured to the same rigorous quality standard — verified per production batch in our in-house QC laboratory.

◆ 01

Outstanding Electrical Insulation

Dielectric strength of 12-35 kV/mm — effectively isolates components in low to high voltage systems (1 kV-110 kV), preventing short circuits and arcing.

◆ 02

Wide Temperature Range

Withstands continuous working temperatures from 400°C to 1000°C (varies by grade) — maintains performance stability in furnaces, engine bays, and industrial ovens.

◆ 03

Robust & Durable

High bending strength (≥80 MPa) withstands mechanical stress without flexing or cracking — making it suitable for motor slot insulation and heavy-duty mechanical spacers.

◆ 04

Flame & Chemical Resistant

UL94 V-0 rated (non-combustible) and resistant to oils, weak acids, and moisture (water absorption ≤1.5%) — ensuring long lifespan in harsh industrial environments.

◆ 05

Precision Machinability

Easily cut, drilled, or stamped into custom shapes with tight tolerances (±0.1mm) — adapts to complex designs in electrical and mechanical equipment.

◆ 06

Low Thermal Conductivity

Reduces heat transfer between components — improving energy efficiency of heating systems and protecting sensitive parts from overheating.

Product Types

Four Grades — Matched to Your Temperature Class

Each grade is engineered for a specific temperature range and application type. Choose the one that matches your operating environment.

400–600°C

Muscovite Mica Plate

Made from natural white muscovite mica — ideal for 400-600°C applications. Offers good electrical insulation at economical cost.

  • Home appliances
  • Microwaves
  • Low-voltage motors
600–800°C

Phlogopite Mica Plate

Natural amber phlogopite mica for 600-800°C environments. Magnesium-rich composition enhances heat resistance for industrial use.

  • Industrial kilns
  • Transformer cores
  • High-temp pipes
Up to 1000°C

Synthetic Mica Plate
