1. Physical and mechanical properties
Micanite with a two-dimensional sheet-like structure acts as a plane reinforcement in plastics, improving the flexural modulus of elasticity and tensile strength of the product. The physical and mechanical properties of Micanite reinforced plastics are between those reinforced with glass fibers and mineral fillers (such as talc). Compared with glass fiber reinforced plastics, the advantages of mica reinforced plastics are higher modulus and lower warpage. curvature.
The uniform orientation of Micanite in the plastic ensures the anisotropy of the product, prevents warpage and deformation, and also imparts excellent dimensional stability to the product. Micanite is the mineral filler that has the most obvious effect on the shrinkage rate of PP and PA modified materials, which can significantly reduce the molding shrinkage rate of the product.
2. Heat resistance
Mica powder has good thermal stability (high temperature resistance above 600 ℃), which can inhibit the generation of volatiles during the thermal decomposition of plastics while insulating, and improve the thermal stability of the material (thermal deformation temperature and high temperature creep resistance) .
3. Damping performance
The addition of Micanite powder has a great contribution to improving the damping performance of the product. Under the combined effect of the volume effect of the flake filler and the friction effect, the energy loss of the material is large and the damping value is large.
4. UV shielding performance
Micanite is a natural mineral filler with excellent UV shielding performance (over 80% shielding rate) and mechanical enhancement effect. In some application systems (PP), the UV shielding effect can completely replace organic UV absorbers, which greatly reduces manufacturing costs. .
5. Electrical residential properties
Micanite has extremely high resistance as well as is a high-performance insulating product. In the field of low-voltage electrical devices (such as PA-modified leak protection, air buttons, junction boxes, electric parts, etc), and also electrical interaction, mica dental filling is a suitable pick. If you need to make high-insulation plastic products, you can take into consideration including practical filler wet-process mica powder, yet mica with high iron material has low insulation efficiency and also need to be avoided.
6. Barrier efficiency
In the process of plastic processing, with the calendering and also stretching of the product, the Micanite wafer can create a parallel alignment setup in the plastic. Layers of obstacles are formed in the product, making it incredibly tough for gases as well as liquids to penetrate. When gas as well as fluid pass through the plastic, they must frequently bypass and overlook the mica wafer, as well as the penetration path is very tortuous (securing impact as well as labyrinth impact), so Micanite-filled plastic has superb gas and also liquid obstacle homes. Nevertheless, to get superb obstacle result, the diameter-to-thickness proportion of the flake filler ought to go to the very least 50 times, ideally greater than 70 times. The diameter-thickness ratio of wet-process mica powder is as high as 80 ~ 120 times, which can be utilized in plastic materials that require high obstacle buildings.
