Abstract: The present invention relates to a method for producing a self-lubricating plastics material in which a polymer material is first cooled to cryogenic temperatures with liquid nitrogen to give rise to a crumbly, frozen polymer material which, once crushed, is mixed with microcapsules containing a lubricating fluid before then being compression moulded to yield a plastics material with lubricating microcapsules incorporated into the polymer matrix. The resultant self-lubricating plastics material is suitable for the production of sealing elements for reciprocating compressors.
