SABIC’s Innovative Plastics business continues to tune up grades targeting automotive exterior body panel applications.
In an interesting new development, Mitsubishi Motors Corp. (MMC) selected Noryl GTX 989 resin for the front fenders of its 2013 Outlander Sport crossover. The left and right fenders are molded simultaneously in a two-cavity, family-type tool, reducing mold costs and cycle times.
Noryl GTX 989 is a conductive blend of polyamide and modified polyphenylene ether. MMC is the first automotive OEM to use the new grade. Compared to the previous grade, it delivers a 10ºC improvement in heat tolerance, making it a candidate for use in higher-temperature online painting. Importantly, it also reduces the coefficient of linear thermal expansion (CLTE) by 10% vs. previous grades for increased dimensional stability and improved gap and flush management, giving automotive designers the ability to create larger, body panels.
Use of plastic instead of steel reduced vehicle weight by approximately 7 pounds.
