PolyFLEX™ 50 / 50B

Product Features

The PolyFLEXTM 50 / 50B product line is made in the U.S. from a semi-rigid linear low density polyethylene giving it a natural milky white color. This product line contains no plasticizers and very low levels of extractables. It meets the requirements of
the FDA and is the most chemically resistant product offered by Finger Lakes Extrusion. Although PolyFLEXTM 50 is milky white, users are still able to determine if there is flow inside of the tubing. PolyFLEXTM 50B is opaque black and inhibits algae
growth and UV degradation making it a good choice for outdoor use. This material gives users excellent environmental stress crack resistance over low density polyethylene.

  • Semi-rigid and translucent
  • Low in extractables
  • Offers a wide range of working temperatures
  • Resistant to a broad range of chemicals
  • Better stress crack resistance over low density polyethylene
