The Role And Market Of Polytetrafluoroethylene Ultrafine Powder

The role and market of polytetrafluoroethylene ultrafine powder. The average particle size of polytetrafluoroethylene ultrafine powder is less than 5μm, the specific surface area is greater than 10m2/g, the friction coefficient is 0.06-0.07, it has good lubricity, and can be well dispersed in many materials.

Due to the low molecular weight of low molecular weight PTFE, the particle size is fine and soft, it has good dispersibility, and can be evenly dispersed in other substrates to change its properties. Therefore, the main use of polytetrafluoroethylene ultrafine powder is to be used as an additive in other materials to improve lubricity, increase peelability, improve wear resistance, impart anti-fouling and abrasion resistance, improve flame retardancy and increase water repellency.

Polytetrafluoroethylene ultrafine powder can be widely used as a modifier for polymer materials, lubricating greases, inks, coatings, explosives, fuses, rocket solid fuel fillers, etc.

The main applications are as follows:
1. As a modifier for polymer materials: Adding 3% to 25% of polytetrafluoroethylene ultrafine powder to polymers such as PC, POM, PA, PPS, silicone rubber, and propylene rubber can significantly change their lubrication, non-stickiness, wear resistance, and flame retardancy. In thermoplastics, elastomers, and thermosetting plastics, it can improve the wear resistance and non-stickiness of the materials and reduce the surface friction coefficient. In rubber, it can improve the surface properties and mentioned properties of rubber, and improve the crushing strength and friction properties of rubber.

2. As a modified additive for inks: Adding 1% to 3% of polytetrafluoroethylene ultrafine powder to aniline inks, gravure inks, and offset inks can significantly improve the color, wear resistance, and smoothness of printed products, especially suitable for high-speed printing.

3. As a modified additive for coatings: Adding up to 60% of polytetrafluoroethylene ultrafine powder to the coating (different addition ratios have different performances) can improve the anti-stickiness, lubricity, reduce the friction coefficient, improve corrosion resistance, wettability and processability of the coating, etc. It is widely used in food, packaging, electrical appliances, textiles and other departments.

Polytetrafluoroethylene micropowder(PTFE Wax) is a low molecular weight white micro powder resin processed by a special process. It is a low molecular weight free-flowing powder obtained by condensing, washing and drying the dispersion obtained by polytetrafluoroethylene. It not only maintains the excellent properties of polytetrafluoroethylene, but also has many unique properties, good dispersibility, uniform blending, which significantly improves the performance of the substrate. It can be used in inks, engineering plastics, rubber, coatings, paints and other industries.
