What material is the shroud of keglands counter flow chiller made of?

The specification only says pliable polymer, but exactly what is it made of?

To be more specific I would like to know what temperature it can handle? Is it food grade? If it's food grade, to which temperature is it food grade? Ie can I run boiling hot water through the water path? And then use the water afterwards?
