PTFE FEP Clear Ester Polyurethane Chemical Tubing
- Available in Ester or Ether formulations
- Both formulations made from non-toxic ingredients conforming to FDA standards for use with wet and fatty food contact surfaces
- Transparent, flexible, resilient, tough; resistant to oils, greases, and fuels†
- Extremely resistant to weathering††, tearing, impact, radiation, and abrasion
- Wide range of temperature resistance: -95F to 185F (ester)
- Ether-based material is listed by the National Sanitation Foundation (NSF 61) for use with potable water
- Contains no plasticizer which could cause flow contamination or tube hardening
- Can be heat sealed, coiled, fabricated, or bonded
††Hydrolytic Stability - For resistance to moisture and fungi, SUPERTHANE® ether is recommended. (Ester polyurethane does not react well with water, prolonged humid conditions, or attack from fungi.) Ether-based SUPERTHANE® also resists attack from ultra-violet rays, making it a good material for outside use. The material used in its manufacture is listed by the National Sanitation Foundation (NSF 61). SUPERTHANE® is much more resistant to pressure and vacuum applications than corresponding sizes of PVC or rubber. †Although polyurethane is commonly used in fuel applications, due to additives in today’s gasoline and petroleum products, field testing should be performed. When used with Thermobarb® fittings, SUPERTHANE® will not require clamps, provided that working pressures remain at or below 105 psi at ambient temperature. Custom coiled polyurethane is available - call for details. For easy identification, SUPERTHANE® is imprinted with the trademarked name.
