Yes, the Nomex material is more burn resistant. It has a higher flash tolerance. This means it takes a longer time for certain amount of heat to be applied (up to 800F for several seconds I think) before it will melt/burn.
Below are some links to nomex gloves. The USMC also had some nomex hoods made because the current cold weather hoods we have are made from synthetics as well.
