Effect Of Low Molecular Weight Polytetrafluoroethylene Powder(PTFE Powder)

Effect of low molecular weight polytetrafluoroethylene powder, polytetrafluoroethylene powder is white, fine particles, prepared from low molecular weight polytetrafluoroethylene, mainly used as an additive in plastics, inks, coatings, lubricating oils (greases), to improve the non-stickiness and wear resistance of the base material.

Polytetrafluoroethylene powder is a white PTFE powder processed by a special process and surface activated, while maintaining the original characteristics of PTFE, and its biggest feature is good dispersibility. As an additive, it can be used in many fields. The suggestions given in terms of processing and addition are for reference only.

TIANSWAX reminds: One thing is very important, polytetrafluoroethylene powder is evenly dispersed in the base material; polytetrafluoroethylene powder has a smaller particle size and good fluidity, which makes it easy to mix with other materials and has good dispersion in the base material.

1. Polytetrafluoroethylene powder as an additive in plastics:

Improve the wear resistance of the base resin; reduce the surface friction coefficient and improve the sliding property. The polytetrafluoroethylene powder and resin can be directly mixed evenly and then extruded into granules; the polytetrafluoroethylene powder can also be added to the molten resin (side feeding to the melting section of the screw).

Application: injection molding products of thermoplastic plastics, gears, bearings, computer keyboards such as polycarbonate, polyoxymethylene, nylon, PPS, PEEK.

2. Polytetrafluoroethylene powder as an additive in elastomers:

Give the base material good demoulding properties, improve the wear resistance of the material, reduce the surface friction coefficient of the material, and improve the bending strength; add it during the rubber refining process.

Application: silicone resin sealing ring, NBR products, EPDM.

3. Polytetrafluoroethylene powder as an additive in printing ink:

Improve the friction resistance of the ink; the surface is smoother; improve the slipperiness; reduce the blockage of the machine during the printing process; add it directly during the ink production process; add it directly during the ink production process.

Application: lithography, gravure printing, thermosetting ink; offset sheet-fed ink, metal ink, UV ink.

4. Polytetrafluoroethylene powder as an additive in coatings:

During the production of coatings, grind or stir with resins and additives to mix evenly, and the powder should be well dispersed in the matrix. The addition of powder can give the coating better wear resistance, reduce surface “stickiness”, improve surface hydrophilicity, surface texture modification, etc.

Application: cooking utensils, cookware, high-quality coatings, UV varnish, ship paint, plastic paint, aluminum paint, wood paint, coil paint.

5. Polytetrafluoroethylene powder as an additive in oils and greases:

Add directly to the formula, or wet the powder first and then add it to the system. Reduce wear, reduce surface friction coefficient, improve thickening stability and increase boundary lubrication.

Application: lubricating oil, high-viscosity grease.

Tianshi PTFE powder not only maintains all the original excellent properties of PTFE, but also has many unique properties: such as no self-agglomeration, no electrostatic effect, good compatibility, low molecular weight, good dispersibility, high self-lubrication, and significantly reduced friction coefficient.
