PLASTIC

PLASTIC

Mica has a layered structure of aluminum silicate sheets with stable physical and chemical properties .「Mohs Hardness:2–3; Volume Resistivity:1013~15Ω·cm; Breakdown Voltage: 200kv/mm; Coefficient of Thermal Expansion: 7×10-6K-1; High Temperature Resistance: over 600℃」

High quality natural mica mines are selected to produce Plastic Grade mica powder. Through selecting, grinding, washing, soaking, crushing under high pressure and finer screening, Grea Plastic Grade mica retains inner sheet structure, large aspect ratio, high purity, centralized particle distribution and excellent fluidity properties.

产品介绍

Features and Benefits


•  Mechanical properties:Mica’s two-dimensional planar structure plays an enhanced role in the plastics. Adding mica, plastics would have much higher flexural strength and lower warping degree.

•  Overall performance: Mica can be uniformly scattered in the plastics and reduce the rate of molding shrinkage.

•  Heat resistance: Mica not only has  high temperature resistance(over 600℃) but can suppress the productions of volatile matter when plastics in heating decomposition. It improves the materials thermal stabilities.

•  Damping property: Based on the volume and frictional effect of flake filler, mica plays an important role in damping property of plastics.

•  Optical properties: As one kind of natural Anti-UV radiation functional material (Shielding rate ≥ 80%), mica can even replace organic UV absorbents in some polymer composites(such as PP). Adding mica into plastics greatly reduces production costs of the polymer composites.

•  Electrical properties: It is generally known that mica is famous for its insulating properties. Taking mica as filler in Low Voltage Electric Appliance and Electrical Communication Appliance would be an ideal choice.
