I have to work with viscoelastic materials, since I tried to use a silicone polymer (silly putty) which expect to IR transparent properties, however, IR camera shown the black color (means their absorbed IR light).
So, I would like to know that which viscoelastic properties materials (i.e. silicone polymer, memory foam, etc.) are transparent to infrared light? in which when I observe by IR camera their will show the image like IR x-ray vision.
Sorry for poor in English / I'm not sure that this is correct site for ask this question, if you have suggestion please let's me know. :)
