Wanzhu Mining – Mica Flake Introduction

Company Overview

Product Categories

1. Muscovite Flake

   Our flagship product with transparent layered texture. It features top-tier insulation, acid and alkali resistance. Available in large sheets, medium flakes and small fragments, mainly applied to electrical insulation and medium-high temperature heat insulation materials.

2. Phlogopite Flake

   Golden-brown flake with outstanding heat resistance, tolerating higher working temperature than muscovite. It is widely adopted for high-temperature refractory components, welding electrodes and heat-resistant sealing gaskets.

3. Sericite Chips

   Ultra-thin tiny scales with strong lubricity and adhesion, mostly used as auxiliary filler for friction materials, coatings and rubber products.

Core Product Properties

1. Outstanding temperature resistance: Muscovite works steadily at 500–800°C; phlogopite can sustain 900–1100°C without decomposition, cracking or deformation.

2. Superior insulating performance: High voltage breakdown resistance and stable resistivity, free of conductive impurities, ideal insulating substrate for motors and household appliances.

3. Natural layered flake structure offers lubrication and shock absorption, effective for stabilizing friction performance and lowering operating noise.

4. Inert chemical composition, resistant to acid, alkali, oxidation and dampness, maintaining stable performance in harsh outdoor and humid working conditions.

5. Good flexibility and toughness; thin mica flakes withstand thermal shock from rapid temperature shifts without easy breakage.

6. Strict quality control for foreign matter; low content of stone, dark spots and iron, uniform color and flake size batch by batch.

Common Size Specifications

• Large mica sheet: 3–5cm, 5–8cm, above 8cm (for high-end insulation and refractory usage)

• Medium & small flake: 0.5–1cm, 1–3cm

• Granular mica pieces: 10 mesh, 20 mesh, 40 mesh, 60 mesh

• Packaging: 25kg woven bags or ton bulk bags, full-truck transportation supported.

Main Application Industries

1. Electrical Insulation: Insulating gaskets for motors, microwave ovens, hair dryers, transformers and electronic components.

2. Refractory & Thermal Insulation: Raw material for mica boards, furnace lining heat shields, fireproof rolls and high-temperature sealing parts.

3. Brake Friction Materials: Functional filler to balance friction coefficient, reduce brake squeal and extend service life of brake pads for vehicles and industrial machinery.

4. Coatings & Pearlescent Materials: Improve paint weather resistance, anti-cracking performance and surface gloss.

5. Rubber & Plastic Reinforcement: Enhance product strength, dimensional stability and flame retardancy.

6. Other Applications: Welding electrode coatings, fireproof boards, waterproof sealing materials and ceramic fillers.
