Product Features

The PolyFLEX 50 / 50B tubing line is made from a semi-rigid low density polyethylene (LDPE) giving it a natural milky white color. This product line contains no plasticizers and very low levels of extractables. It maintains FDA approval and is the most chemically resistant product offered by Finger Lakes Extrusion. Although PolyFLEX 50 tubing is milky white, users are still able to determine if there is flow inside of the tubing. PolyFLEX 50B tubing is opaque black and inhibits algae growth and UV degradation making it a good choice for outdoor use.
