Teflon PTFE Powder
PECOAT® Teflon PTFE micro powder is a low molecular weight micron-sized white polytetrafluoroethylene powder processed by a special method. It not only retains the excellent properties of PTFE, such as chemical resistance, thermal stability, weather resistance, and temperature resistance, but also has many unique properties, such as high crystallinity, good dispersibility, and easy uniform mixing with other materials. Therefore, it is widely used in the modification of polymer materials to improve the lubricity, wear resistance, non-stickiness, and flame retardancy of the substrate, significantly improving the performance of the substrate. In addition, it can also be used as a high-performance additive in industries such as inks, coatings, and plastics.

Adding PECOAT® Teflon PTFE micro powder to a product can improve its non-stick, wear-resistant, and scratch-resistant properties. This is because it has the following characteristics:
Firstly, due to the extremely low surface energy of PTFE micro-powder, it can form a non-adhesive protective layer with the product surface, thereby improving the non-stickiness of the product.
Secondly, PTFE micro-powder has high wear resistance, which can reduce the wear and friction coefficient of the product during friction, and prolong the service life of the product.
Finally, PTFE micro-powder also has high hardness and scratch resistance, which can reduce the risk of the product surface being scratched and improve its scratch resistance.
PECOAT® Teflon PTFE Micro Powder has excellent dispersibility, compatibility and lubricity.
Dispersibility: Refers to the ability of PTFE micro powder to be uniformly dispersed in liquids or gases. Good dispersibility can increase the apparent specific surface area of PTFE micro powder, increase the contact area between PTFE micro powder and the surrounding environment, improve its compatibility and reactivity with other materials.
Compatibility : Refers to whether PTFE micro powder can form a uniform mixture with other materials after mixing. Good compatibility can improve the processing performance of PTFE micro powder, enhance its adhesion to other materials, and improve its mechanical properties.
Lubricity : Refers to the low viscosity and low surface tension of the surface of PTFE micro powder. Good lubricity can reduce the friction and adhesion between PTFE micro powder and other materials, improve its wear resistance, lubricity, and chemical resistance.
Adding PECOAT polytetrafluoroethylene (PTFE) micro powder to resins can enhance their chemical and temperature resistance. This is because it has the following properties:
Firstly, since the molecular structure of PTFE micro powder on the surface is different from that of resin molecules, adding PTFE micro powder to resins can increase the surface energy of resins, thereby improving their anti-adhesive properties and chemical corrosion resistance.
Secondly, PTFE micro powder has extremely high thermal stability and temperature resistance, and can remain stable and not easily decompose under high temperature environments, thereby improving the high-temperature resistance of resins.
Lastly, PTFE micro powder has good mechanical strength and wear resistance, which can improve the durability and service life of resins.
PECOAT PTFE micro powder has excellent self-lubricating properties and can be used for dry lubrication of sliding parts, which can effectively reduce friction and improve the service life of the parts.
Firstly, it has a low coefficient of friction, which means that it can reduce the friction between the sliding parts and improve the lubrication performance.
Secondly, it has a high melting point and is resistant to high temperatures, which means that it can maintain its lubrication performance even under high temperature conditions.
Finally, it has good chemical stability, which means that it is resistant to corrosion by chemicals and can maintain its lubrication performance even in harsh environments.

PECOAT® Teflon PTFE Micro Powder has excellent physical and chemical properties, mainly used on coatings, friction materials, plastics, lubricants, electronic materials
PECOAT® PTFE micropowder can be used as a solid lubricant on its own, or as an additive for plastics, rubber, coatings, inks, lubricating oils, and greases. When mixed with plastics or rubber, various typical powder processing methods such as blending can be used, and the amount added is 5-20%. Adding polytetrafluoroethylene micropowder to oil and grease can reduce the coefficient of friction, and adding just a few percent can increase the life of the lubricating oil. Its organic solvent dispersion can also be used as a release agent.
Adding 1%-3% of ultrafine polytetrafluoroethylene powder to aniline ink, gravure ink, and offset printing ink can significantly improve the color, wear resistance, smoothness, and other properties of printed products, especially for high-speed printing.
The addition of PTFE micro powder to coatings can produce a variety of high-performance coatings that meet the needs of industrial development for the coatings industry. The micro-powder addition amount is generally sufficient at 5‰-3%, and the main role is to improve the viscosity and lubricity of the coating, reduce the coefficient of friction, and improve wear resistance. It also improves corrosion resistance and reduces moisture absorption, improves the spray casting performance of the coating, increases the critical film thickness, and improves its thermal forming performance. In anti-fouling coatings for ships, the content of PTFE micro-powder can reach 30%, effectively preventing the attachment of soft-bodied animals to the bottom of the ship.
Coating series added with PTFE micro-powder mainly include polyimide, polyether sulfone, and polysulfide. Even after high-temperature baking, they still exhibit excellent anti-adhesive properties and continuous high-temperature use without changes in performance. As anti-stick coatings, they are widely used in the food and packaging industry and can also be used in household appliances, tableware, metal parts resistant to chemical corrosion, automobiles, and electronic components, especially for automobiles, household appliances, and daily necessities, and have excellent application prospects in industrial production.
The addition of PTFE micro-powder to lubricants and greases can improve their high-pressure and high-temperature lubrication performance. Even if the base oil is lost, PTFE micro-powder can still act as a dry lubricant. The addition of PTFE micro-powder to silicone oil, mineral oil, or paraffin oil can significantly increase the viscosity of the oil. The amount of PTFE micro-powder added depends on the viscosity of the base oil and the desired thickness and application area of the lubricant, usually ranging from 5% to 30% (mass fraction). Adding PTFE micro-powder to grease, rosin, mineral oil can produce high-quality lubricants, which are currently widely used in ball bearings, wear-resistant bearings, lubricated guide rails, slide rods, open gears, chemical equipment valves, and precision machining flat sealants.
In addition, PTFE micro-powder can also be used as a dry lubricant like graphite and molybdenum disulfide, with excellent results. It can be mixed with propane and butane to be used as a non-stick and anti-wear spray agent, rocket additive, etc. PTFE micro-powder can also be an effective thickener for lubricating greases.

- Store in a cool and dry place and avoid severe vibration and exposure to high temperatures during transportation.
- In the field of coatings: 0.1%-1.0%, added in the early stage of production process and requires high-speed stirring for optimal dispersion.
- In the field of engineering plastics: added according to product requirements, or consult the technical department of our company.
The product is easy to disperse and can generally be dispersed using a conventional mixer. For difficult-to-disperse systems, a high-shear mixer (such as a three-roll mill, high-speed disperser, or sand mill) can be used for dispersion.
