| NEMA G11 can be used in higher
temperature applications than NEMA G10. It retains high mechanical
strength at temperatures up to 150° C, and
retains 50% of its flexural strength at elevated temperatures. It is used
in the electrical industry and anywhere a high strength electrical
insulator is needed in high temperature applications.
