Clariant Masterbatches’ specialty compounding group has developed a new nylon 66 compound that allows injection molding to replace machining in lubricated products such as bushings.
The firm says its Renol 6642 contains 2 percent molybdenum disulfide to provide lubrication to complement the compound’s toughness and high compression strength. Flexural strength at yield is 17,000 pounds per square inch and flexural modulus is 410,000 psi, the firm reports in a news release.
Lubricated plastic compounds are replacing metal in many applications. Such compounds containing molybdenum disulfide typically have been offered for machining of bar stock but machining technology is costly due to long processing time and wastage. Clariant claims its new product cuts scrap rates and reduces manufacturing time by 75 percent or more. For uses where extremely tight tolerances are required, parts can by injection molded and then machined to finished dimensions.
Clariant’s specialty compounding group in North America is based in Albion, Mich.
