PVDF Tubing / KYNAR® (for aggressive chemicals)
|
|
|
|
Tubing KYNAR PVDF (Polyvinylidene fluoride) is strongly suitable with acid fluids ( Hydrocloric Acid or Sulphuric acid). It is a valid and cheaper alternative to Teflon PTFE. Good aging resistance Good impermeability with gases. Operating temperatures ranging from –20 C° to +80 C°. (See herebelow derating Temp. Table) Supplied in 100 mts coils up to 12mm OD, or 50 mts coils for higher Diameters. Colours: natural; Black. |

PTFE / PFA Tubing (Teflon) (for very aggressive fluids)
|
Suitable with double sleeve JACO fittings
|
 |
| Teflon PTFE (politetrafluoroeth.) is the most popular fluorine Polymer. Has excellent resistance to acids and bases, even at higher temperatures. Can work also at low Temp. up to -40 C°. . Inert to Oxygen, Ozone and UV Rays. An antistatic version is specifically suitable in Textyle Industry or Painting (with powder). Teflon FEP o PFA has great impermeability to most of gases and is transparent like glass. Particularly suggested to get retractile coils even at high temperatures. |
