DuPont Fluoroplastic Now Has the Highest Temperature Rating of Any Plastic in the UL Plastics – Component Database : Underwriters Laboratories Inc. Recognizes DuPont ECCtreeme® ECA 3000 PerFluoroplastic Resin with 300°C Rating, Expanding Innovative Possibilities and Enabling Faster Product Design

WILMINGTON, Del., Feb. 11, 2014 – DuPont Fluoropolymer Solutions (DuPont) announced today that Underwriters Laboratory Inc. (UL) has certified DuPont ECCtreme® ECA 3000 perfluoroplastic resin with a 300°C rating for a minimum-thickness of 0.75 mm (and above) in the UL Plastics Online Certification Directory. The new rating is based on UL mechanical, electrical, and fire performance testing.

DuPont ECCtreme® ECA 3000 perfluoroplastic resin is designed to perform in very harsh environments found in the oil and gas, aerospace, automotive, semi-conductor manufacturing, electronic communications and power industries.

Previously, UL had given ECA 3000 perfluoroplastic resin a 300°C rating for a higher minimum-thickness of 3.0 mm. This new classification (UL Component File E54681) supersedes the previous UL rating but includes the previous rating of 3.0 mm thickness. The rating change also offers lower minimum thickness with 300 C Relative Thermal Index (RTI) temperature; therefore, the resin will operate successfully and consistently at temperatures up to 300°C, both electrically and mechanically. In a parametric search, UL found that DuPont ECCtreme® ECA 3000 perfluoroplastic resin has the highest RTI values in the UL Plastics – Component database.

“UL is a globally recognized testing, listing and certifying laboratory with a wealth of experience in this type of testing,” said James R. Hoover, global regulatory affairs manager, DuPont Fluoropolymer Solutions. “We’re thrilled that DuPont ECCtreme® ECA 3000 perfluoroplastic is the highest temperature-rated plastic – not just fluoroplastic – currently available in the UL Plastics – Component database worldwide. This new UL certification gives our customers confidence that our offering has been tested to meet key material pre-selection requirements, and therefore enables them to design and market their end products faster.”

With a 40-year history in the electrical and electronic materials business, wire and cable products made with DuPont fluoroplastics are known for their excellent chemical resistance, superior electrical properties, and high service temperatures. DuPont offers a wide variety of perfluoroplastic resins processible by various means, all of which offer high dielectric strength, a low dielectric constant, low loss factors and extremely high heat resistance. Fluoroplastic resins from DuPont surpass most materials in their level and stability of dielectric properties over a broad range of extreme thermal and environmental conditions.

DuPont (NYSE: DD) has been bringing world-class science and engineering to the global marketplace in the form of innovative products, materials, and services since 1802. The company believes that by collaborating with customers, governments, NGOs and thought leaders, we can help find solutions to such global challenges as providing enough healthy food for people everywhere, decreasing dependence on fossil fuels, and protecting life and the environment.
