Sabic has revealed a new resin that is suited for insulation film used in electric vehicle (EV) battery modules to help improve protection against short circuits and fire propagation.
This high-performance, polyphenylene ether (PPO)-based Noryl NHP8000VT3 resin is engineered with patented technologies to help meet the stringent demands of higher-voltage batteries (600-800 volts).
“Transitioning from standard, 400-volt EV batteries to higher voltages offers the potential to shorten charging times, extend the range and improve energy management within the vehicle,” said Joshua Chiaw, Director, Business Management, LNP & Noryl, Specialties, Sabic.
“However, designing higher-voltage batteries requires the invention of breakthrough materials, such as our new Noryl resin for insulation films. This new solution is the industry’s first thermoformable material to achieve the highest CTI performance level as well as meet stringent flame retardancy standards. Sabic continues to focus intensively on developing innovative material solutions that can propel e-mobility adoption by addressing safety, performance and range anxiety challenges.”
“The Noryl NHP family is our next-generation PPO portfolio with enhanced FR performance,” said Jenny Wang, Director, Formulation and Application, APAC, Specialties, Sabic.
“It includes Noryl NHP6011 and NHP6012 resins for battery modules and housings. Our new Noryl NHP8000VT3 resin further diversifies the series with more-robust CTI performance. To help support the acceleration of future electric vehicle battery designs, we have raised the bar in CTI PLC values and thin-wall flame retardant performance suitable for insulation materials. This achievement attests to our broad and deep technical knowledge and resources, and a strong commitment to continuous innovation.”
Noryl NHP8000VT3 resin provides a novel solution to the drawbacks of incumbent insulation films made with polycarbonate (PC) and polypropylene (PP) by delivering stronger CTI performance and thinner-wall FR capability.
This exceptional material can help advance EV battery technology by contributing to occupant safety, weight reduction and higher efficiency for extended range.
Sabic will be featuring its new Noryl NHP8000VT3 resin at The Battery Show Europe 2022 in Stuttgart, Germany, June 28-30 (Hall 8, Booth F10), and will be showcasing an array of insulation film and thermoformed parts.
Noryl NHP8000VT3 resin’s ability to meet the UL94 V0 standard at 0.25 mm means it can provide a high level of flame retardance at a thinner film gauge than PC or PP, potentially freeing up valuable space in the battery pack.
