Product Features

The Ester-PUR FLEX 85 product line is made from an ester based polyurethane resin. This material is much more abrasion and impact resistant than PVC while maintaining flexibility and clarity. Urethane also possesses a high level of chemical compatibility. Since this is a pure polyurethane resin, it contains no plasticizers and has a very low level of extractables making it a great product for high purity applications. This formulation is NOT recommended for aqueous solutions.

Ester-PUR FLEX 85 Tubing

  • Resistant to atmospheric ozone, aliphatic hydrocarbons and petroleum products
  • Pure polyurethane; contains no plasticizers and low levels of extractables
  • Complies with FDA CFR21 food packaging
  • Tough; resists tearing and abraison
  • Flexible at low teperatures

Typical Applications

  • High-purity applications
  • Fuel lines
  • Instrumentation
  • Cable jacketing
  • Gas sampling lines
  • NOT recommended for use with aqueous solutions
