It has recently been claimed by some of our competitors that Aflex’s BIOFLEX product is inferior to the competitor’s product which it is designed to improve upon and replace.

In particular, it has been claimed that BIOFLEX is weaker, and has a shorter service life.

In fact, exactly the opposite is true.

A testing program recently conducted confirmed this. BIOFLEX and CORROFLON samples were run side by side with competitors’ products, including smoothbore FEP, PTFE or PFA lined Rubber hose products, and also smooth flex type products, on a "Rolling U" test rig.

The 1" bore samples were "Rolled" at the minimum bend radius and at the maximum working pressure quoted for the competitor’s product.

Results were as follows:

• BIOFLEX Hose - 1.25 million cycles, no failure.
  - No leakage occurred, so test discontinued. No signs of damage, or wear.
• CORROFLON Hose - 147,159 cycles to failure.
  - Hose leakage caused by rupture of the hose liner.
• Competitor’s smoothbore FEP lined Rubber Covered Hose - 9,149 cycles to failure.
  - Hose leakage caused by severe failure of the hose liner, breakage of the helix wire, and damaged rubber and braid.
• Competitor’s convoluted smooth flex type hose - 7,151 cycles to failure.
  - Hose leakage caused by very severe failure of the hose liner and braid components. (One competitor’s design of smooth flex type hose failed after only 64 cycles!).

These remarkable results have not been exaggerated in any way, yet they very strongly refute the claims made against BIOFLEX by Aflex’s competitors.

In fact, they confirm the claims made all along by Aflex, that BIOFLEX and CORROFLON are the best designed, toughest and most reliable PTFE lined hose products available today.

These results also raise grave doubts about the reliability and potential service life of competitors’ products, in particular the smooth flex product, in critical applications.
