Anybody know the Melting point of K'nex?

This probably looks like a really strange thing to ask, but I need to know what kind of temperature K'nex can endure before it softens and/or looses shape. 

I am building something which will need to be able to withstand hot water/steam splashing onto it (but not  submerged in it), as well as being near a considerable heat source. 
 
I've look for what they are made of, but nothing has come up, though I presume they are made of a mix of low-to-mid-temperature polymers with a  high toughness. 

Don't get any mad ideas!!!

Thanks, a bit of Aluminium foil should help a bit with shielding it :)
