Product Highlights

Four Advantages That Exceed Natural Mica

Synthetic mica is manufactured through advanced laboratory synthesis — delivering ultra-pure composition, superior temperature tolerance, and precision processing capabilities beyond what natural mica can offer.

◆ 01

Ultra-High Temperature Tolerance

Synthesized via advanced processes — continuous temperature tolerance 1000°C, intermittent peak 1200°C. Far exceeds natural mica's temperature ceiling, making it the ideal choice for extreme high-temperature industrial scenarios.

◆ 02

Outstanding Electrical Insulation

Dielectric breakdown strength reaches 20 kV/mm, with dielectric loss factor as low as 0.001-0.002 at 50Hz. Maintains stable insulation in high-voltage electric fields — effectively prevents equipment short circuits and leakage risks.

◆ 03

Precision Custom Processing

Supports stamping, cutting, and forming based on customer drawings with minimum tolerance ±0.1mm. Meets requirements for custom shapes and complex structural parts — e.g., EV battery module cover plates, heating equipment custom insulation pieces.

◆ 04

Strong Chemical Stability

Resistant to acid/alkali corrosion — stable performance within pH 3-11 range. Excellent aging resistance — service life exceeds 10 years in humid, oily, and harsh environments. Significantly reduces equipment maintenance costs.

◆ 05

99%+ Ultra-Pure Composition

Laboratory-synthesized fluorophlogopite with 99%+ purity. No natural impurities (iron oxide, quartz) that weaken electrical performance — delivers uniform, consistent batch-to-batch quality for precision applications.

◆ 06

UL94 V-0 Fire-Rated

Certified to UL94 V-0 flame retardant standard — self-extinguishing behavior for EV battery thermal runaway prevention. Critical safety component preventing cascading cell failure in lithium-ion battery systems.

◆ Why Choose Synthetic Mica Sheet

Engineered for the Most Demanding Applications

Synthetic mica delivers what natural mica cannot — lab-controlled purity, precision dimensional tolerance, and ultra-low dielectric loss. The premium choice for EV batteries, HV transformers, and aerospace.

🔥

1200°C Peak Temperature

Continuous 1000°C, peak 1200°C — far exceeds natural mica's ~1000°C ceiling. Survives extreme thermal cycling in aerospace and industrial furnace environments.

⚡

tan δ 0.001–0.002

Ultra-low dielectric loss factor at 50Hz. Minimizes power loss in HV transformers (110kV+) — critical for energy-efficient industrial-scale power distribution.

🎯

±0.1mm Precision

CAD-based CNC stamping, cutting, and forming. Delivers custom shapes and complex structural parts for EV battery module covers and heating equipment.
