Chinese plywood

[gert]

Had a salesman in today selling Chinese plywood.

1/2" Occume 9ply (counting very thin face veneers) C face D back Phenolic glue, poplar core- very uniform. Did a 20 min microwave boil test with no apparent detriment.

$22.00 Ca a sheet.

Probably quite suitable for interior work.

HEY GERT: A new Hardwood wholesale yard in Port Aurthur has this china made 1/2 occume 9 ply also. It has the black glue lines which I'm told is the phenolic type. I saw no obvious voids. He wanted 30$ a sheet. He says its cheaper to off-load ply from the ocean transport container vessels than any thing he can get inland. There was a post recently about a large boatbuilding shop that was using it a week or two back. Interesting.

Not sure how pertinent this comment is, but I bought some maple 1/4" chinese ply for interior wainscotting in my house. Had a hell of a time finishing it.
There is something in the glue I'm guessing that made it resist the polyurethane finish. Acted just like silicone contamination when lacquering. Sort of like large fisheye. It just would not flow out over certain areas, even after multiple coats and sanding and wiping with acetone between coats. I would have thrown the ply away, but they were already built into frame and panel.

i have had many problems with the chinese birch ply that has been in the cabinet market for years. The thicknesses very greatly. The wood used for the outer finish veneer looks smooth but as soon as finish touches it the grain opens up. The wood isnt dried properly, it will warp very quickly. The outer veneers are cut so thin that the glue saturates it so that finish does not want to stick (probably your problem John).
