MANY BENEFITS

Milflon® retains its self-lubricating properties despite harsh working conditions.

WHAT IS IT?

Milflon® is a fluoropolymer containing PTFE (polytetrafluoroethylene). Specially designed by Miltech International (registered trademark), it is a self-lubricating synthetic composite material. Although it has many intrinsic properties, it does not contain any hazardous substances and is in compliance with the ROHS directive.

Milflon® is self-lubricating

When two parts of a mechanism are in contact and rub against each other, the use of a lubricant alone may not solve every friction problem. Moreover, for reasons of congestion or inaccessibility, cost or simple choice, a lubricant product may not be usable in a satisfactory manner. Milflon® presents the enormous advantage of being able to be used on its own and in a dry environment, as it is self-lubricating.

Milflon® is resistant to corrosion

For assemblies designed to function in chemically aggressive environments, the use of a lubricant can be tricky. The corrosive fluid can act as a solvent on the lubricant and significantly alter its properties. Worse still, the surfaces of materials can be directly attacked by the chemically aggressive product.

Milflon®, on the other hand, has great chemical inertness, and is therefore particularly resistant to corrosion.

Milflon® is not affected by a vacuum or by a large thermal range

Milflon® works very well in a high vacuum, with minimum volatility and no other lubrication solution. It is perfectly usable in clean rooms for assembly of sensitive components. In addition, Milflon® keeps its characteristics unaltered at the lowest temperatures (down to -240°C) and at the highest temperatures (up to +280°C). It may, for example, be used with liquid nitrogen or to avoid the installation of an expensive lubricant cooling system.

Milflon® allows substantial savings

Milflon® is more wear-resistant than other plastics. Its replacement frequency is therefore lower. In addition, by avoiding the introduction of a lubrication system which is complex and costly by nature, it makes it possible to make significant savings.
