The company’s polypropylene (PP) compound H1090 resin and Stamax 30YH611 resin can be processed using sheet extrusion and thermoforming to form large and complex structural parts, such as battery pack covers, enclosures and module separators.
According to Sabic, the materials have inherent thermal and electrical insulation and weight advantages when compared to stamped sheet metal.
“By providing new alternatives to traditional materials and processes, Sabic can enable customers to design and manufacture the next generation of battery components while driving down costs and gaining a competitive advantage,” said Abdullah Al-Otaibi, general manager.
In tests, exposing the two resins to vertical and horizontal flames at 1200°C for 10 minutes reportedly showed improved flame-retardant behavior with efficient charring and intumescence keep the temperature of the reverse side of parts lower than 210°C, Savis said. Intumescence is improved by using non-brominated/non-chlorinated fiber resin that meets the UL94 V0 standard at 1.5 mm. H1090 and Stamax 30YH611 also have improved dimensional stability, low coefficient of thermal expansion (CTE) and a good creep resistance.
