PTFE composite electroless nickel plating is a plating in which an electroless nickel plating film is coated with Teflon particles (polytetrafluoroethylene: PTFE).
In addition to the characteristics of electroless nickel plating, PTFE exhibits excellent slipperiness, slidability, water repellency, and mold releaseability.
It is especially effective for parts that require wear resistance and slipperiness, such as pistons and plungers.
Due to the REACH regulation in Europe, PFOA (perfluorooctanoic acid) and its salts that are contained in trace amounts in raw materials have been regulated. In response to this, we plan to switch to PFOA-less processing in December, 2021.
Even with the current treatment, we have confirmed that the amount of PFOA and its salts in the film is 25 ppb or less.

Features
Features 1Functional film with the characteristics of PTFE
The most significant feature is that it exhibits the characteristics of PTFE.
PTFE has a lower coefficient of friction and higher water repellency than other functional polymers. Electroless nickel PTFE composite plating has both characteristics.
Excellent dimensional accuracy
Because it is electroless plating, the film thickness is uniform, and the dimensions can be precisely controlled.
It enables improved releasability while maintaining the dimensional accuracy of the mold.
