ECCtreme™ ECA Fluoropolymer Resins

A Unique Class of High-Temperature Fluoropolymers

ECCtreme™ ECA fluoropolymers combine the beneficial properties typical of fluoropolymers with the ability to maintain peak operational performance under extreme temperatures and conditions. These products offer:

  • Excellent chemical resistance
  • Superior electrical properties
  • High service temperatures, going beyond the long-standing 260 °C (500 °F) limit in wire, tubing, and molding applications

Features and Benefits

This unique class of high-temperature, melt-processable fluoropolymers offers a low dielectric constant, dissipation factor, and coefficient of friction while driving function to a higher level than regular fluoropolymers provide. Additional properties include:

  • Outstanding electrical insulating properties at high temperatures
  • A UL-listed 300 °C (572 °F) rating¹
  • Increased stress-crack resistance
  • Exceptional chemical resistance and improved permeation resistance to CH₄, O₂, CO₂, and water
  • Robust melt processability
  • Low flammability

Pushing Boundaries

[Body] ECCtreme™ ECA fluoropolymer resins facilitate epitaxial co-crystallization (ECC) because their function improves when heat-treated up to 300 °C (572 °F)¹. It is designed to meet the demand for high-temperature fluoropolymers in sustainable energy production, such as geothermal energy, and the oil and gas, military, aerospace, chemical, and automotive industries.

Applications include:

  • Wire and cable
  • Injection- and compression-molded parts
  • Extruded tubing
  • Exhaust sensors
  • O₂ sensor wiring
  • Transmissions

¹The Underwriters Laboratory Inc. (UL) certified the ECCtreme™ ECA fluoropolymer resins with a 300 °C (572 °F) rating for a minimum thickness of 0.75 mm,² the first to achieve this temperature rating.

¹300 °C (572 °F) rating is based on UL 746B testing. Not a guarantee of performance; see section "Important Notice."

²This classification is based on mechanical, electrical, and fire performance testing and supersedes the previous UL rating, but does include the previous rating of 3.0 mm thickness. This family of resins has the highest relative thermal index (RTI) values in the UL plastics component database.

Important Notice

ECCtreme™ ECA fluoropolymer resins are relatively new products targeting extreme applications, which require properties beyond the operating limits of typical fluorpolymers. As a result, the performance characteristics and other properties of these products are not guaranteed, and the user is responsible for evaluating and determining whether this Chemours product is suitable and appropriate for a particular use and intended application. The conditions of the evaluation, selection, and use of the Chemours product can vary widely and affect the use and intended application of the Chemours product. Because many of these conditions are uniquely within the user’s knowledge and control, the user must evaluate and determine whether the Chemours product is suitable and appropriate for a particular use and intended application.
