Matte PETG properties compared to normal PETG

Hello, I bought a couple 5kg rolls of your Matte PETG. Before I open them I need to know if they have the same heat resistance as normal PETG? I make auto parts like grills, side skirts, etc and have been using Creality PETG and it's resistance to heat has been great. I'd like to move to your filament for the 5kg spools but only if it will be as resistant as the Creality PETG.

thanks!
