company news about Application of Tetrafluoro Micropowder in Silicone

Tetrafluoroethylene micro powder, also known as low molecular weight polytetrafluoroethylene micro powder, or polytetrafluoroethylene ultrafine powder, or polytetrafluoroethylene wax, is applied in silicone gel. It is a white micro powder resin, which is a dispersed solution obtained by the polymerization reaction of tetrafluoroethylene and then condensed
Made by washing and drying, it has excellent properties such as heat resistance, weather resistance, cold resistance, low friction, non stickiness, chemical stability, and electrical insulation performance.
In terms of rubber, PTFE micro powder can improve the surface and volume properties of rubber. For example, adding 5% -8% (mass fraction) PTFE micro powder to organic silicone rubber, nitrile rubber, fluorine rubber, EPDM rubber, and polychlorobutadiene can improve the friction performance, wear performance, and demolding behavior of the main polymer, and improve the crushing strength of rubber. However, the elastic behavior of rubber is not significantly damaged, which can reduce the tearing phenomenon caused by rubber during demolding.
PTFE micro powder is a white, free flowing low molecular weight powder mainly used as an additive and applied in various material systems.
The purpose of PTFE micro powder:
1. Thermoplastics and thermosetting plastics: can enhance lubrication and wear resistance.
2. Rubber and elastomers: improve their wear resistance and tear strength.
3. Lubricating oil and grease: thickening, solid lubrication.
4. Printing ink: anti scratch, anti clumping, anti fading, protects image quality, and improves productivity.
5. Coatings and coatings: low friction, low wear, scratch resistance, non stick resistance, low torque, noise reduction, waterproofing, and oil resistance.
Precautions for using PTFE powder:
PTFE powder can be applied in many fields, and it is very important to ensure that the micro powder is uniformly dispersed in the matrix material. High speed mixers and drum mixing equipment are more suitable for dry powder mixing; A propeller type mixing device is more suitable for use in solvents and oils
Prepare. If the viscosity of the system is high, it is recommended to use glass ball grinding. For higher system viscosity, it is recommended to use ring rolling grinding.
