4 Did you know? Water Content in Polyamide (PA66, PA12) Polyamide is a hygroscopic material, meaning it absorbs and releases water. The mechanical properties of polyamide are significantly affected by its water content – especially flexibility and minimum tensile strength. Polyamide is most stable at optimum atmospheric conditions of 73° F (23° C) and 50 percent relative humidity. Under these conditions, the degree of water saturation of PA66 is around 2.5 percent. For PA12, the water saturation rate under these conditions is 0.7 percent. Material Expertise HellermannTyton's product engineers and chemical scientists work every day to develop the longest lasting products in the industry while protecting your bottom line. Off-the-shelf materials are appropriate for general-purpose applications, but in solar, will provide short-term value that can quickly lead to uncontrolled maintenance costs. Simple UV rated and PA66 outdoor grade materials deliver in certain situations, but fail to measure up to environmental extremes. Our solar materials are formulated with UV stabilizers, UV absorbers or exceptionally durable base plastics designed for extended lifespans. Depending on your application, we offer budget-friendly solutions that outlast so-called value-priced products – all the way up to our new 25-year PVDF for the most maintenance-free cable management you can get.
