Chemours ECCtreme™ ECA 2000 Fluoroplastic Resin
Categories:	Polymer; Thermoplastic; Fluoropolymer
Material Notes:	ECCtreme™ ECA1 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 UL746B2 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 meltprocessed 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. Information provided by Chemours.
