Manufacturing Polyurethane Coil Tubing Since 1980

Freelin-Wade started manufacturing polyurethane tubing more than 35 years ago. With the introduction of Fre-Thane®, it remains our flagship product to this day. Fre-Thane® coil tubing is our most versatile spiral plastic tubing product, with more options and variations available than any other tubing we offer.

Ether-Base vs. Ester-Base Polyurethane Coils

Polyurethane was developed in 1937 by German chemist Friedrich Bayer. It quickly gained popularity as a replacement for rubber during World War II, while its first commercial application came as a fiber in the stretchable, lightweight fabric that would eventually be known as Spandex.

There are now two standard classes of polyurethane, ether-base and ester-base, which are popular for countless applications across various industries. Chemically, both are comprised of the same basic ingredients: polyol alcohol and isocyanate. The difference is in the type of polyol used, ester or ether. Both produce similar, but different, reactions when combined with isocyanate.

Generally, ester-based polyurethane is less expensive; however, it degrades far more rapidly when exposed to moisture than the ether-based alternative. For this reason, Freelin-Wade manufactures all of our Fre-Thane® polyurethane single tube spiral plastic tubing from ether-based resins.
