| ECCtreme™ ECA1 4000 fluoroplastic resin is a new class of perfluoroplastic specifically designed for use in extreme applications requiring an operating temperature up to 300 °C (572 °F)2 in combination with excellent electrical properties and/or chemical resistance. Chemours developed ECCtreme™ ECA 4000 fluoroplastic resin in response to industry demand for a melt-extrudable, high-temperature fluoroplastic resin for wire and cable applications. ECCtreme™ ECA 4000 fluoroplastic resin has been recognized as a 300 °C (572 °F) rated material per UL 746B2 by Underwriters Laboratories. Compared with ECCtreme™ ECA 3000 fluoroplastic resin, ECCtreme™ ECA 4000 fluoroplastic resin has a slightly higher melt-flow rate (MFR), making it ideal for constructions needing 2–10 mil (0.05–0.254 mm) of insulation. ECCtreme™ ECA 4000 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, Broad wire processing window of operation. In addition, ECCtreme™ ECA 4000 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 280–300 °C (536–572 °F) for a prolonged period.Information provided by Chemours. |
