Halar®, Tefzel™ Linings

The above video explains how our proprietary Helium Leak Test ensures the integrity of our Halar® and Tefzel™ linings.

Consider Halar® ECTFE or Tefzel™ ETFE as your liner material if you’re looking for a cost-effective fluoropolymer that can protect your equipment and tanks from both acids and caustics.

Halar® and Tefzel™ both protect against corrosion caused by the full pH spectrum.  They are multi-environment standouts, making them good choices for a neutralization tank, for instance, because they can easily tolerate the swings in pH levels.  They also tolerate heat better, up to 250°F when bonded to a substrate with a toughened epoxy adhesive.

In addition to improved chemical corrosion protection, Halar® and Tefzel™ offer increased permeation protection, the other major threat that fluoropolymer linings address.

And Halar®  has the lowest coefficient of expansion of any of the fluorinated resins, making it a good choice for high thermal-cycling environments.  Plus, its added smoothness resists surface build-up of particulates.

The performance advantages of Halar® and Tefzel™ do cost a bit more, but not much.

Halar®  and Tefzel™ resins are used for coatings as well as liners.  To learn more, please visit our Halar® and Tefzel™ Coatings page.
