Description

Klüberalfa lubricants based on perfluorinated polyether (PFPE) have been developed for specific applications where optimum performance under lifetime lubrication conditions is required. The PFPE base oils contained in Klüberalfa HX 83-302 have an
exceptionally flat viscosity-temperature curve. With a consistency class of NLGI 2, Klüberalfa HX 83-302 can be used at temperatures as low as –60°C and even ensures loadbearing lubricating films at temperatures as high as 240°C.

Klüberalfa HX 83-301 and Klüberalfa HX 83-302 should be used for all those applications requiring a high kappa value anda very good load-carrying capacity of the lubricant over a wide temperature range.

For special applications Klüberalfa HX 83-301 is available (NLGI grade 1).

Application

Plastics and seals

Klüberalfa HX 83-301 and Klüberalfa HX 83-302 offer exceptionally low friction values along with a good stick-slip behaviour, even in long-term tests. The temperature of friction points subject to dynamic loads can therefore be reduced in many applications, which has a positive effect on the component’s service life.

The service temperature range indicated exceeds most standards specified by e.g. the automotive industry. Depending on the component Klüberalfa HX 83-302 is applied in small to very small quantities. Application example: O-ring lubrication in pneumatic switches in the automotive components industry.

General behaviour towards plastics and elastomers:

Lubricating greases based on fluorinated polyether oils and PTFE are generally regarded as neutral towards elastomers and plastics (possible exception: perfluorinated rubber). Nevertheless compatibility with the materials should be tested, especially prior to series application.

Rolling and plain bearings

Klüberalfa HX 83-302 is suitable for special applications subject to very high service temperatures and frequent thermal fluctuations. Its consistency ensures low starting torques even at low temperatures. Application example: Electric motor bearings with a low starting and a high operating temperature.

Clean room technology

Contrary to the general opinion, special lubricants like Klüberalfa HX 83-301 and Klüberalfa HX 83-302 do not constitute an additional particle source, but on the contrary often contribute to clearly reducing wear-related particle emission.

Application notes

For optimum lubrication results, we recommend cleaning the friction points with white spirit 180/210 followed by Klüberalfa XZ 3-1. Then apply clean, dry compressed air or hot air to remove any remaining white spirit residues.

For initial lubrication, the friction points must be clean and bright (i.e. free from oil, grease or perspiration) and free from particles. We will be pleased to give advice on the optimisation of lubricant life.
