Analytical tools precisely control Nylon characteristics and production

Paul Boughton

In a new web-based seminar from Malvern Instruments, scheduled for Tuesday, July 31, Dr. Wei-Sen Wong will explore the 'Nylon characterization technology package'.

The webinar outlines how the utilization and combination of several analytical technologies employed within Malvern’s Viscotek family of instruments are assisting manufacturers of nylon to precisely control physical properties, processability and performance characteristics.

Nylon (the generic name for a family of polyamides) is an extremely versatile synthetic thermoplastic that is made of repeating units linked by amide bonds. It is widely known that nylon fibres are manufactured for products such as fabrics, carpets, strings and ropes, and as solid nylon in mechanical parts for construction, automotive assemblies and many houseware items.

Manufacturers rely on important and complementary information about molecular weight distribution, structural characteristics and viscosity to better control the physical properties, processability and performance characteristics for these diverse applications. The webinar highlights how the techniques of gel permeation chromatography (GPC), flow injection polymer analysis (FIPA) and dilute solution viscosity (DSV) combine to efficiently meet this important analytical need, from development through to manufacturing and QC. 

GPC analysis provides extensive molecular information to support the development of new specifications for defined applications and the optimization of manufacturing processes. It is a cornerstone technique for polymer scientists, enhanced through the use of multiple detectors that maximize information from each experiment. The Viscotek DSV system is a highly automated option for fast, safe and efficient intrinsic viscosity measurement, a primary parameter for determining processing performance. FIPA is a tool for rapid molecular weight, molecular size, and intrinsic viscosity measurement, well-suited to QC and screening within process development. Unlike GPC it does not provide distributions of molecular properties, but the upside is productivity – as many as 6 – 10 samples can be measured per hour.
