The New Nylgutå¨ is the first product developed and patented by Aquila. The New Nylgutå¨ is nor common Nylon or Carbon (Fluorocarbon fishing line or PVDF), or a mix of them. It is a plastic compound of three different components. Compared to Nylon, the New Nylgutå¨ produces a better sound and stays in tune better, this because the moisture absorption is less of .1% against the 2.0% of Nylon normally employed for the musical strings (i.e. Du Pont Tynexå¨ polyammide 6-12). Due to the higher density, similar to that of pure gut (1.30 gr/cm3), the New Nylgutå¨ produces a better sound than Nylon and it is not so metallic like those of the so- called ‰Û÷Carbon‰۪ (Fluorocarbon) PVDF strings. In other words, the New Nylgutå¨ is probably the first genuine synthetic gut in the world. Made in Italy
