For nearly 70 years, the majority of fly lines have been made from PVC – a naturally rigid plastic that requires the use of plasticisers to make PVC lines functional. These plasticisers are anything but a permanent part of a PVC line. You see, from the minute it’s made, a PVC line begins breaking down - leaching plasticisers into the environment and contaminating you and the waters you fish. Once it has shed enough of these, it becomes prone to cracking, even failure. If that’s not enough, as it decomposes, PVC is known to release Dioxins - a group of lethal, bioaccumulating toxins. Consequently, it’s virtually impossible to safely recycle a PVC line. All of which is why Airflo never uses PVC. Instead, our lines are made from Polyurethane - an inert, stable, fully recyclable material that requires no plasticisers and lasts far longer than PVC.
