laser vaccume box.....flame retartant cardbord honycomb

[sloppie]

I run a lmi cm-110 400 watt laster machine. I been using 1" flame retartant paper honeycomb in the vaccume box. The manufacuter says there is no longer such a thing to supplie me. I run thin acrylics and polycarbinates so smoke and refection marks are a huge factor in the outcome of the piece parts I produce.

Was wondering If anyone can give me a contact to a vender of paper honeycomb?

Or does anyone use a differnt process other then the paper honeycomb?

Thanks
