French chemicals company Arkema announced that Kynar 720 polyvinylidene fluoride (PVDF) has been recertified for UL746C from Underwriters Laboratory.
In UL746C testing, Kynar PVDF resin successfully passed Xenon Arc testing of 1000 hours of UV exposure and seven-day water immersion at 70°C without the addition of organic or inorganic pigments.
The results comply with the requirements for Polymeric Materials – Short Term Property Evaluations, UL746A, sixth edition, and Polymeric Materials – Use in Electrical Equipment Evaluations, UL 746C, sixth edition, both of which were revised in February 2013.
According to the company, Kynar components are suitable for outdoor use with exposure to ultraviolet (UV) light, water, and immersion. They are used for chemical process piping, electrical wire and cable jacketing, instrumentation and control equipment, and pumps used in aviation and military transportation equipment.
