To
support broader adoption of electric vehicles (EVs), SABIC launched two grades of NORYL
resin that support demand for lighter, thinner, and more crash-resistant
battery modules and housings. NORYL NHP6011 and NHP6012 resins address key
consumer requirements for EVs: improved safety, range, and power. They deliver
enhanced robust flame retardancy and impact strength to meet stringent
industry-related safety standards, as well as thin-wall molding capability to
reduce weight and accommodate more cells, helping to extend vehicle range and
boost performance. These novel glass fiber-reinforced NORYL resins feature
proprietary polyphenylene ether (PPE)-copolymer technology and are the latest
additions to SABIC’s growing NHP
family of materials for mobility applications.
Improved Properties Align with Evolving Battery Trends
Several
trends are shaping the future of EV batteries. Stricter flame retardance
requirements are now in force, concerning the safety of lithium-ion batteries.
In Europe and Asia, battery module materials must meet the UL 94 V-0 standard. NORYL
NHP6011 and NHP6012 resins provide non-chlorinated/non-brominated flame
retardancy that meets UL 94 V-0 requirements at 1.5 mm. In addition, they
supply high stiffness and impact strength for crash protection. The two
products differ in their glass fiber loadings to accommodate specific customer
requirements for stiffness.
Another key trend in EV battery manufacturing is miniaturization. Battery
manufacturers are striving to fit more cells in existing or smaller spaces to
increase vehicle power and range. The dimensional stability and good flow
properties of the NORYL grades enable thin-wall designs for cell frames,
retainers, and battery pack
top covers, increasing energy density while minimizing
weight and space.
These materials provide dielectric performance with a comparative tracking
index (CTI) of 2 to help avoid electrical shorts among tightly packed cells. NORYL
NHP6011 and NHP6012 resins provide resistance to acid vs. polycarbonate (PC),
better resistance to moisture compared to polyamide, and a low specific
gravity.
