Extended Physical Data for Advanced Applications of Nylacast Nylons


Professor Malcolm Fox, head of research and development, Nylacast

Use of Nylon-6 in high specification industrial components is increasing more and more. The physical properties of nylon-6 to specify these precision industrial components now extends beyond the standard technical data sheet.

Responding to the requirement for extended data measurements , Nylacast has determined the physical properties of nylon-6 and its various specialist formulation from -60 to +175oC. The physical properties measured for this temperature range include tensile, flexural and compressive strengths and moduli, ‘% Extension at Break’, and also impact strengths together with Shore Hardness. The physical property/temperature plots are shown to be dependent on formulation. The main conclusion to be drawn is that the glass transition temperature, Tg, has a significant effect for some properties but not on others.

The requirement for an increased depth of important data continues – in response to increasing customer requests, Nylacast has measured the tensile and compressive creep of the Nylacast grades of Nylon-6 at different loads, strains and temperatures.

Underlying these developments is the increasing need for Certificates of Analyses for high specification, precision, Nylon-6 applications. For these applications, ‘warehouse nylon’, source unknown, which might conform to a technical data sheet is not good enough. Nylacast is happy to discuss the physical properties of its Nylon-6 grades and its formulations at temperatures between -60 and +175oC (in some cases down to -100oC!) with customers and design a suitable Certificate of Analysis for supplying nylon-6 to a high specification application’.
