Polymer micro powder

Polymer micro powder is a type of polymer material that is prepared into fine powders and has a wide range of characteristics and applications. The following is a detailed introduction about polymer micro powder:

1. Definition and Properties

• definitionPolymer micro powder is a fine powder made of polymer materials, with particle sizes typically in the micrometer range.

• nature：

• Granularity levelUltrafine powder has different particle size grades, generally divided into fine powder (such as below 500 mesh), ultrafine powder, and ultrafine powder (such as around 500 to 10000 mesh).

• physical characteristicsHas highly customizable, excellent physical and mechanical properties, and diverse applicability.

2. Preparation method

• Physical methodsThe main equipment includes crushers, classifiers, and collection devices such as airflow mills, vibration mills, Raymond mills, ball mills, etc. There are mainly two forms of physical methods for preparing ultrafine powders: dry method and water method.

• chemical synthesisPrepared by chemical reaction under the conditions of anhydrous ethanol as solvent and polyvinylpyrrolidone as stabilizer.

• Mixed methodA preparation method based on a combination of physical and chemical synthesis methods, commonly used for the production of nanomaterials.

3. Application Fields

• 3D printing materialsPolymer micro powders are widely used in 3D printing, and their highly customizable and excellent performance can greatly improve the diversity and manufacturing efficiency of 3D printed products.

• coatingAdding polymer micro powder to coatings can enhance their adhesion, hardness, and glossiness, as well as improve their resistance to dissolution, environmental factors, and ultraviolet radiation.

• otherPolymer micro powder can also be used to manufacture high-precision components, such as FEP micro powder, which is suitable for this due to its excellent chemical inertness, thermal stability, electrical performance, and low friction coefficient.

4. Specific polymer micro powder - FEP micro powder

• Chemical inertnessFEP micro powder has extremely strong chemical corrosion resistance and can resist corrosion from most organic and inorganic acids, alkalis, solvents, and oxidants.

• thermal stabilityCan maintain good performance even in high temperature environments.

• Electrical performanceHas excellent insulation performance and low dielectric constant, suitable for the manufacturing of high-frequency electronic devices.

5. Precautions

• When using polymer micro powders, attention should be paid to their particle size grade and physical properties to ensure their optimal performance in specific applications.

• During the preparation and storage process, corresponding safety operating procedures should be followed to avoid harm to human health and the environment.

From the above introduction, it can be seen that polymer micro powders have broad application prospects and important value in modern industry.
