PLASTIC

With high temperature resistance (600℃) and stable physical and chemical properties, Mica has a Mohs hardness of 2～3 and a specific gravity of 2.7～3.5, which can be split into extremely thin flakes, elastic and bendable; Its volume resistivity is 10 13-15Ω•cm, breakdown voltage can reach more than 200kv/mm, thermal expansion coefficient about 7×10-6K-1.
Grea "Plastic Grade Mica Powder" is prepared by complicated processes including fine ore selection, wheel wet grinding, cyclone classification, dry dehydration. It has a complete sheet structure, large radius-thickness ratio, high purity, concentrated particle size distribution and excellent processing fluidity and many other advantages.

▎Features and Benefits

• One of the lightweight modified materials—the bulk density of mineral powder ≤0.18g/cm³

• Improving the dimensional stability of thermoplastic resins--reducing shrinkage, inhibiting warpage, and increasing heat distortion temperature

• Increasing the flexural modulus--high radius-thickness ratio sheet structure, two-dimensional enhancement, ensuring the resin anisotropy

• Insulation material--low magnetic substance, high insulation, meeting the technical requirements of smart and electronic assembly applications
