Product Overview

What Is Synthetic Mica Tape?

Synthetic mica tape is the premium choice for the most demanding high-temperature and high-voltage insulation applications. Unlike natural mica mined from the earth, our base mica is grown in a laboratory through a controlled fluorophlogopite synthesis process — yielding a material that is 99%+ pure and completely free from natural impurities such as iron oxide and quartz.

This ultra-pure composition dramatically reduces the risk of electrical breakdown in sensitive equipment operating at high voltages. It's why synthetic mica tape is specified in the most critical applications — EV traction motors, aerospace engine bays, MRI scanners, and nuclear reactor power systems.

Our synthetic mica tape is available in two engineered series: Z-series with glass cloth reinforcement for maximum mechanical strength, and N-series without reinforcement for smooth high-voltage dielectric applications. Every batch is manufactured to identical specifications — eliminating the batch-to-batch variability inherent to natural mica.

Product Features

Seven Properties That Define Synthetic Mica Tape

Ultra-pure synthetic production eliminates every variable that limits natural mica. Every property below is verified per batch in our QC laboratory.

◆ 01

Outstanding Electrical Insulation

Dielectric strength of 25-40 kV/mm, suitable for high-voltage systems up to 110 kV — reliable protection against arc formation and short circuits.

◆ 02

Extreme Temperature Resistance

Withstands continuous service temperatures up to 1000°C — maintaining stability in aerospace engine bays or nuclear reactor environments.

◆ 03

Ultra-Pure Composition

Free from natural impurities such as iron oxide and quartz — reducing the risk of electrical breakdown in sensitive high-voltage equipment.

◆ 04

Excellent Flame Retardancy

Classified as self-extinguishing (UL94 V-0 grade) — delays flame propagation and enhances safety in enclosed electrical systems.

◆ 05

Mechanical Durability

Reinforcement layer delivers high tensile strength (≥40 N/cm in Z-series) — resistant to tearing during installation and vibration in moving parts.

◆ 06

Chemical & Moisture Resistance

Unaffected by most acids, alkalis, oils, and moisture (≤0.5% moisture absorption) — long-term stable in harsh industrial or outdoor environments.

◆ 07

Consistent Quality

Synthetic production eliminates natural mica's variability — guaranteeing consistent thickness, insulation, and heat resistance across every batch.

◆ 08

Customizable Formats

Glass cloth for high mechanical strength, or polyester film for enhanced flexibility in bending applications — paired to your use case.
