ECCtreme ™ ECA 1 2000 fluoroplastic resin is a class of perfluoroplastic specifically designed for use in extreme applications requiring an operating temperature up to 300 °C (572 °F) in combination with excellent electrical properties and/or chemical resistance. Chemours developed ECCtreme ™ ECA 2000 fluoroplastic resin in response to industry demand for a melt-extrudable, high-temperature fluoroplastic resin for molding applications. ECCtreme ™ ECA 2000 fluoroplastic resin has been recognized as a 300 °C (572 °F) rated material per UL746B 2 by Underwriters Laboratories. Compared with ECCtreme ™ ECA 3000 fluoroplastic resin, ECCtreme ™ ECA 2000 fluoroplastic resin has a lower melt-flow rate (MFR), making it ideal for extruded sheet and molding applications requiring increased stress-crack resistance. ECCtreme ™ ECA 2000 fluoroplastic resin can also be extruded into sheets, rods, or tubing, as well as into compression and transfer molded parts.

ECCtreme ™ ECA 2000 fluoroplastic resin can be melt-processed using standard high-temperature fluoroplastic equipment, at standard operating speeds, and possesses physical, electrical, and chemical properties characteristic of polytetrafluoroethylene (PTFE). Its features include:

• UL rated for 300 °C (572 °F)

• High melting point of ~320 °C (608 °F)

• Excellent dielectric properties

• Excellent chemical and permeation resistance

In addition, ECCtreme ™ ECA 2000 fluoroplastic resin demonstrates enhanced properties (e.g., higher melting point, increased melt viscosity, improved stress crack resistance) when subjected to post-processing heat treatment as shown in Table 1. This effect, known as epitaxial co-crystallization (ECC), occurs when the resin is heated between 290–300 °C (554–572 °F) for a prolonged period. This post-processing heat treatment offers a unique combination of higher stress crack resistance in combination with higher crystallinity, which is favorable to lower permeation. Furthermore, this grade offers improved creep resistance versus conventional fluoroplastics.
