Influence on plastics performance:
1. Improved optical performance.
2. Improved insulativity and fire resistance.
3. Improved tensile strength and bending modulus.
4. Improved size stability, reduced shrinkage, warpage and tortuosity.
Note: suitable for PP-R, PP, ABS, PE, PA, PU and PVC as well as in functional master batch and plastic engineering.
Processing Technology
There are two manufacturing processes of mica powder: dry grinding and wet grinding. We have our own factories to produce these two products.
Dry ground mica powder is produced by physical grinding without changing any natural property of mica. We adopt total enclosed filling system to guarantee quality during the whole production process. In the screening process,we also employs proprietary equipment and technology to ensure uniform particle distribution and stable quality. As to its superior performance, dry ground Muscovite has been extensively used in production of various products, including fiber cement construction panels / wallboards, plastics, rubber, paint, coating, welding electrodes, oil drilling and brake pads.
