THK Co., Ltd. Begins Accepting Orders for THK Original "PFAS-Free Vacuum Grease"
THK Co., Ltd. has started accepting orders for its original "PFAS-Free Vacuum Grease" (model number: AFPF), addressing growing concerns and regulations regarding PFAS (per- and polyfluoroalkyl substances). This new product is optimized for vacuum environments, such as those in semiconductor manufacturing equipment, offering low vapor pressure, low friction, low dust generation, and low outgassing performance.

THK Co., Ltd. (Minato-ku, Tokyo; Representative Director and President: Takashi Teramachi, hereinafter "THK") has begun accepting orders for its original "PFAS-Free Vacuum Grease" (model number: AFPF).
PFAS-Free Vacuum Grease (model number: AFPF)
In recent years, regulations against PFAS (per- and polyfluoroalkyl substances), which are suspected of posing health risks to humans, have been strengthening, particularly in Europe and the United States. For fluorinated greases widely used in special environments such as vacuum, there is an increasing risk of future restrictions on the use, manufacturing, and import of their constituent substances, PFPE (perfluoropolyether) and PTFE (polytetrafluoroethylene).
In response to these environmental regulatory risks, THK has developed its original "PFAS-Free Vacuum Grease." This grease is manufactured with a PFAS-free and metal-free formulation and process, possessing the essential low vapor pressure, low friction, low dust generation, and low outgassing performance required for vacuum applications, making it optimal for linear motion products. It reduces contamination risks within semiconductor manufacturing equipment and achieves smooth movement and excellent lubrication performance.
THK will continue to develop and provide products suitable for various environments, tailored to customer needs, based on the technology and know-how cultivated as a top manufacturer of mechanical components.

Features
・Usable under high vacuum
It has low vapor pressure and low outgassing performance, making it usable under high vacuum.
・Low friction
It has low friction and excellent rolling stability.
・Low dust generation
Due to its excellent low dust generation, it can be used without contaminating the surrounding environment.
* "PFAS-free, metal-free" in this grease means that fluorine and fluorine compounds, Cu, Zn, Li, and other metal elements are not intentionally included in the grease components and manufacturing process.
* This grease will be sold as a standalone product only in Japan. Overseas expansion is planned sequentially.
[About THK Co., Ltd.]
Since its establishment in 1971, THK has focused on developing various products as a creative development-oriented company. In 1972, it commercialized the "LM Guide (Linear Motion Guide)," which was the first in the world to achieve "rolling" in the linear motion parts of machinery. This dramatically improved the performance of mechatronics equipment such as machine tools. In recent years, it has also been used in railway vehicles, medical equipment, high-rise buildings and residences, and amusement equipment, bringing various innovations worldwide.
