Polyphthalamide VESTAMID® HTplus shows exceptional dielectric strength
VESTAMID® HTplus M1933, manufactured by Resource Efficiency segment of Evonik, Essen, scored excellent results in tests of its Relative Temperature Index (RTI). The results confirmed that components made of this polyphthalamide (PPA), which is reinforced with 30% fiberglass, can be expected to show constant electrical properties and consistently high dielectric strength at high ambient temperatures in long-term operation (20,000 hours).
Given the growing number of requirements such as weight savings, miniaturization and higher performance in smaller and more compact assemblies, component developers quickly reach feasibility limits with existing plastic solutions. VESTAMID® HTplus M1933, which is designed for a wide range of markets and applications, offers precisely these properties and meets the applicable fire safety requirements. According to tests performed by Underwriters Laboratories (UL), the high-temperature polymer VESTAMID® HTplus M1933 reaches the flammability rating V0 for all colors from a wall thickness of 0.4 mm.
"Our material's electrical RTI is clearly superior to the other commercially available materials starting from a wall thickness of 0.4 mm," commented Global Business Director Dr. Simon Ting on the test results. "VESTAMID® HTplus M1933 also scored equal or better than competitor materials in all other tested Parameters." The property profile includes excellent flow characteristics and outstanding surface qualities in components made from the PPA. Developers of plastic components, for example in the electrical industry, can therefore make even better use of the very high VESTAMID® HTplus long-term service temperature than before.
