Frequently Asked Questions

What is Phlogopite soft sheet?

Phlogopite soft sheet (also called flexible mica sheet or mica roll) is a flexible insulation material made of phlogopite mica paper reinforced with glass fiber cloth and impregnated with a special silicone resin. It remains flexible at room temperature.

What is the difference between soft and rigid mica sheets?

Soft mica sheets are flexible and can be rolled or bent around curved surfaces. Rigid mica sheets are hard plates used for structural support and cannot be bent without breaking.

Is this material suitable for EV batteries?

Yes, it is widely used in New Energy Vehicles (NEVs). It serves as a thermal barrier between battery cells (e.g., blade batteries) to delay or prevent thermal runaway propagation, ensuring passenger safety.

Does it produce toxic fumes when heated?

No. Phlogopite soft sheet is eco-friendly, halogen-free, and asbestos-free. It does not produce toxic gases even when exposed to high temperatures up to 850°C.

Can I die-cut this material?

Yes, the material has excellent processability. It can be easily die-cut into custom gaskets or shapes to fit specific gaps in battery modules or equipment.

What is the standard size?

It is typically supplied in rolls with a width of 1000mm. The length per roll varies (e.g., 20m, 50m) depending on the thickness.

Is it resistant to chemicals?

Yes, it has good chemical stability and is resistant to acids, alkalis, and oils, as well as being resistant to corrosion and hydrolysis.

What reinforcing material is used?

We use alkali-free glass fiber cloth as the reinforcing material on one or both sides to enhance the tensile strength and flexibility of the mica paper.

Does it produce dust?

High-quality phlogopite soft sheets are designed to produce minimal dust or floating particles, making them safe for clean assembly environments like battery production lines.

Can I request a sample?

Yes, we offer samples for testing. Please contact our sales team with your specific thickness and application requirements.
