| Bore Profile |
Smoothbore, rippled around bends
-Good Flow Rate
Easy Clean |
√ |
Smoothbore, slightly rippled
-Good Flow Rate
Easy Clean |
√ |
| Liner material |
FEP or other Fluoroplastic Liner
Good but not as good as PTFE |
 |
PTFE Liner
Best for chemical resistance and temperature resistance |
√ |
XLPE or UHMWPE
Fair chemical resistance |
X |
Process Fluid
Contamination Risk |
High risk - adhesive layer can leach in to contaminate the process fluid through pinholes in the thin wall liner, caused by static discharge, flex-induced porosity, hose kinking etc. |
X |
No risk - no adhesive layer - no non-FDA approved materials used in hose construction |
√ |
| Flexibility |
Fair to Poor
Very stiff, with a large minimum bend radius |
X |
Good
More flexible, reduced minimum bend radius |
√ |
*Flex Life
("Rolling U" Test) |
Poor, typically from 50-10,000 cycles to failure |
X |
Excellent, 1,000,000+ cycles without failure |
√ |
| Kink Resistance |
Fair |
 |
Good |
√ |
| Helical Wire |
Carbon Steel (can corrode) |
X |
304 Stainless Steel |
√ |
Cut Through or
Puncture Resistance |
Fair
(Textile braid protection) |
 |
Good
(Stainless Steel wire braid protection) |
√ |
Antistatic Liner Quality
To FDA Requirements
(<2.5% High Purity Black) |
Often more than 2.5% black, often unevenly dispersed, leading to carbon agglomerates which contaminate process fluid |
X |
Always less than 2.5% black, very evenly dispersed and guaranteed agglomerate-free. 'leachable and extractable' testing yields zero carbon. |
√ |
| Fire Resistance |
Not tested or approved for Fire Resistance |
X |
Rubber Covered grade tested and approved 'Fire Resistant' to BS5173 Section 103.13 |
√ |
| *The "Rolling U" test is shown on the Aflex Hose Website, 'Aflex News > Bioflex and Corroflon compared to competitors products' |
