That is plywood that has layers bonded together with resin. Nine ply marine is bonded together and it may have an oak veneer like the seat board in a bow window.
Oriented strand board is manufactured in wide mats from cross-oriented layers of thin, rectangular wooden strips compressed and bonded together with wax and resin adhesives (95% wood, 5% wax and resin[citation needed]).
Plywood is a tremendously useful contruction material, used in building houses, furniture, and many other things. Since it is made by gluing wood together in sheets, plywood can be effectively any size that you want, and it does not tend to warp since it is made with layers having an alternating grain direction.
birch plywood like other plywood is lots bits of wood stuck together with glue or resin
The wood chips themselves are natural, but the VOCs in the adhesives/resin used to bond the chips together can be harmful.

Ureaformaldehyde is a type of synthetic resin, it is one of the binders/adhesives used in particle board and plywood manufacture.
this is the poly-condensation reaction of urea and formaldehyde at acidic medium ..this is milky type productive used as adhesive in plywood industry.
From the top of my head: Ceramics, most plastics, wood when it is dry , mica, Kraft paper, resin bonded fibre or paper

You use a thick plywood as the base for this project. Stick an edge around it then glue items onto the plywood. For durability ,you can pour clear resin over the items once set in place. This will give a hard,lasting finish.
Yes, the longer u use it the better. he is right because the composite layers are bonded together with resin when you hit with the bat enough or roll the bat the resin is smushed and the bat has more pop alot more its kinda like braking in a glove
