Nylon 66 Moisture


The great interest recently in the plastic industry has spurred more demands in thermoplastics to replace certain metals in manufacturing automotive parts, power tools, and lawn and garden tools. This drives a movement to develop materials and products with higher performance, less weight, better cost savings, and better resistance to fatigue.

Advantages and Problems of Nylon 66

Nylon has that high performance and easy processing. Nylon 66 adds cost savings. However, it absorbs moisture from the surrounding environment, creating a constant challenge for engineers. This moisture affects the polymer properties making it harder to process. The intensification in moisture may cause deep changes in the material’s behavior since it reduces strength, stiffness, and frequency.

Solve the Problems by Controlling the Moisture

With careful controls, the moisture absorbed by nylon can be reversed with drying in an oven. MoistTech has used our more than 30 years of experience in moisture measurement to create a line of NIR sensors that can measure and control the amount of moisture in nylon during processing. For real-time product control, our sensors:

  • Are unsurpassed in performance
  • Provide stable, reliable, constant measurements
  • Are cost effective non-contact measuring devices
  • Mount above the assembly line, before and after dryers, and anywhere moisture measurements are needed
  • Ignore conveyor belts, small gaps in product, color changes, and the height of the product
  • Send digital or analog signals
  • Use RS232 or Ethernet communications to reach your computer
  • Are easily maintained since no calibrations are required
