Nylacast Moly Cast Nylon 6, MoS2 Filled
Categories: Polymer; Thermoplastic; Nylon (Polyamide PA); Nylon 6 (PA6); Nylon 6, MoS2 Filled

Material Notes: Nylacast Moly is a cast nylon material in which improved crystallisation occurs by the addition of Molybdenum Disulphide. On account of this the superficial hardness increases (providing excellent machine ability) and simultaneously the general mechanical and anti-friction properties are improved. Due to the fact that the crystal structure breaks down immediately before the melting temperature is reached, the thermal properties of the material are improved over the basic grade. MoS2 provides a degree of self lubrication leading to an improvement in the wear properties of the material. These improved properties, combined with lower water absorption, extend the range of applications that Moly has over Natural cast nylon. Dynamic bearing applications at elevated operating temperatures of up to 105ºC are particularly suited to this material.
