NyeTorr® & NyeClean®
NyeTorr®, NyeClean® and NyeVac® are chemically stable, non-toxic, low-vapor-pressure, synthetic lubricants designed for cleanroom and in-vacuum applications such as those found in the semiconductor and aerospace industries. These lubricants typically contain a PTFE thickener and a cyclopentane (MAC) or perfluoropolyether (PFPE) base oil which are well suited for wide temperature applications where exposure to harsh chemicals may be a concern.
These lubricants improve the performance of bearings, linear guides, ball and lead screws, and seals by:
- Protecting against friction & wear
- Preventing corrosion
- Extending component life
- Ensuring component reliability
- Preventing contamination
- Controlling precision motion
PFPE vs MAC lubricants
The NyeClean® product line consists of PFPE chemistries while the NyeTorr® product line consists of both PFPE and MAC chemistries. Both PFPE and MAC lubricants are recommended for vacuum environments because of their low vapor pressures and low outgassing properties. PFPE lubricants offer better high temperature performance (up to 250 °C) when compared to MAC lubricants (up to 150 °C). Additionally, PFPE lubricants offer inherent chemical inertness, which translates to unsurpassed resistance to oxidation and hydrolytic degradation, and provides excellent elastomer compatibility. Due to their unique base oil chemistry and additive packages, MAC lubricants provide superior wear protection and bearing life performance. Most MAC and PFPE products are ultrafiltered. NyeTorr® and NyeClean products comply with PFOA regulations.
NyeTorr® lubricants are recommended for applications operating under high vacuum and high temperature where contamination is a concern. NyeTorr® base oils are processed to offer the lowest outgassing of any lubricant from Nye. To ensure low particle and low outgassing qualities, each lot is ultrafiltered and tested per ASTM E595 to ensure the products meet vacuum stability requirements.
