PTFE fine powder is a white, low-molecular-weight free-flowing powder. Due to its stable molecular structure of -(-CF2-CF2-)n, it has excellent chemical resistance, thermal stability, high weather resistance aging (over ten years), UV resistance, high temperature resistance (long-term application temperature around 260℃), a wide range of operating temperatures (-200 to +260℃), good non-stick properties, high electrical insulation (1017Ωcm), high flame retardancy, and excellent self-lubrication.
The performance of PTFE fine powder is mainly determined by its molar mass, particle morphology, and groups on the molecular chain. PTFE fine powder obtained through radiation cracking has high dispersibility and can blend uniformly with other materials; it has a long-term operating temperature of -200 ~ 260℃ and chemical stability similar to polytetrafluoroethylene. It can withstand acids, alkalis, strong oxidizers, and can be molten but has poor cohesiveness. It can be widely used as a modifier for polymer materials, lubricating oils, inks, coatings, fillers for explosives, fuses, rocket solid fuels, etc. The main applications are as follows:
When used as a modifier for polymer materials, the PTFE fine powder produced by PTFE fine powder manufacturers plays a crucial role. Specifically, by precisely incorporating 5% to 25% PTFE fine powder into a series of polymer materials such as polycarbonate (PC), polyoxymethylene (POM), polyamide (PA), polyphenylene sulfide (PPS), silicone rubber, and propylene rubber, the physical and chemical properties of these materials can be significantly optimized. For example, enhancing their lubrication properties reduces energy consumption and wear during processing and usage; improving wear resistance extends the lifespan of the products; and enhancing flame retardancy provides strong safety assurance, making these polymer materials more widely and reliably used in fields such as electronics and electrical appliances, automotive manufacturing, and aerospace.
As a modifier additive for inks, the addition of PTFE fine powder produced by PTFE fine powder manufacturers has brought revolutionary changes to the printing industry. By adding only 1% to 3% PTFE fine powder to aniline ink, gravure ink, and offset ink, the overall quality of printed products can be significantly improved. This is reflected not only in the more vibrant and saturated colors of the prints, significantly enhanced wear resistance, and the prints maintaining their clarity and gloss even after long-term storage or frequent contact; but also in the improvement of smoothness, making the printed surface more delicate and improving the tactile feel. These characteristics are especially suitable for high-speed printing environments, not only improving production efficiency but also ensuring high-quality output of printed products, meeting the dual demands of the modern printing industry for high efficiency and high quality.
In the coatings field, the application of PTFE fine powder produced by PTFE fine powder manufacturers as a modifier additive is also widespread and effective. By flexibly adding up to 60% PTFE fine powder to coatings, the performance of the coatings can be greatly enriched. The enhanced non-stick property makes the coating surface less likely to attract dust, stains, etc., making it easy to clean and maintain; the reduced friction factor and improved lubricity reduce wear and tear between the coating and other objects, improving the ease of use; at the same time, enhanced anti-corrosion extends the lifespan of the coating, effectively resisting the erosion of environmental factors. Additionally, optimizing wettability makes coatings easier to apply evenly, improving construction efficiency; and improved processability grants the coatings a wider range of applications.
