Sinof is a PTFE fine powder manufacturers, always adhering to the business philosophy of "customer first," committed to providing customers with more product choices. Its PTFE fine powders are processed from PTFE raw materials into fine powder substances through specific processes. These fine powders can be adjusted according to different application needs to meet various industrial requirements.
PTFE fine powders have extremely high chemical stability, being almost impervious to any chemical medium, including strong acids, strong alkalis, and various organic solvents. This characteristic allows it to maintain long-term stable performance in corrosive environments.
PTFE fine powders exhibit excellent high-temperature resistance, capable of long-term use in high-temperature environments without performance degradation. Its long-term usage temperature range is generally between -190℃ and 250℃, with some special varieties capable of working at even higher temperatures.
PTFE fine powders possess an extremely low surface energy, resulting in very low friction coefficients and non-stick properties. This makes it perform excellently in scenarios requiring reduced friction and wear, such as in lubricants and sealing materials. Additionally, it is often used as a coating material for non-stick cookware.
PTFE fine powders have good weather resistance, able to resist erosion from environmental factors such as ultraviolet rays and ozone, maintaining long-term stable performance. This makes them very useful in outdoor applications and in scenarios requiring long-term exposure to harsh environments.
PTFE fine powders offer excellent electrical insulation properties, making them suitable for use as electrical insulation materials. Their high resistivity and low dielectric constant enable widespread use in the electronics and electrical fields.
Although PTFE fine powders are inherently difficult to process, they can be compounded or modified with other materials to manufacture products in various shapes and sizes. Additionally, they can be processed into various complex shapes and structures through specific processing methods (such as molding, sintering, etc.).
Polymer Material Modifiers: PTFE fine powders can be added to PC, POM, PA, PPS, silicone rubber, butyl rubber, and other polymer materials to significantly improve their lubrication performance, wear resistance, non-stickiness, and flame retardancy. The addition amount typically ranges between 3% and 25%, depending on the properties that need improvement and the characteristics of the base material.
Ink Modification Additives: Adding 1%~3% PTFE fine powder to aniline inks, gravure inks, offset inks, etc., can significantly improve the color, wear resistance, and smoothness of printed products, making them especially suitable for high-speed printing.
Coating Modification Additives: Adding PTFE fine powders to coatings can enhance the coating's non-stickiness, lubrication, lower friction coefficient, improve corrosion resistance, wettability, and processability. The addition amount can be as high as 60%, with different addition ratios yielding different performance characteristics, widely used in food, packaging, electronics, textile, and other industries.
Lubricants: PTFE fine powders exhibit excellent lubrication properties, making them directly usable as lubricants, especially in scenarios requiring extremely low friction coefficients.
Release Agents: Their organic solvent dispersions can be used as release agents, having important applications in mold manufacturing and plastic processing.
Filling Agent for Explosives, Fuses, and Rocket Solid Fuels: Due to the good chemical stability and high-temperature resistance of PTFE fine powders, they are also used as fillings in these fields.
Manufacturing Various Shaped Profiles and Parts: PTFE fine powders can also be used to manufacture rods, tubes, films, bearings, gaskets, valves, and other shaped profiles and parts, widely applied in machinery, chemical, aerospace, electronics, defense industry, advanced technology, medical and health, and electrical insulation fields.
