Birch B Sap G1S/Uniboard Hardrock Maple 992 TFL Back - P/B Core 5/8" 49x97
This plywood has a rotary cut birch face and Uniboard Hardrock Maple 992 TFL (thermally fused laminate) back.
Birch plywood is characterized by light tan to pale yellow sapwood with red to ruddy heart wood. The grain is tight and smooth with normal amounts of figure and other characteristics.
The Particleboard Core (PBC) is composed of wood particles which vary in size bonded together with urea formaldehyde. It is the least expensive core option for hardwood plywood, offering a smooth, void-free surface for veneer faces.
Very uniform in thickness and density, PBC is one of the heaviest core options for hardwood plywood construction, weighing as much as 100 lbs per 3/4? panel. It has the least amount of structural (spanning) strength compared to the other core options and is subject to the greatest amount of expansion if exposed to moisture.
PBC is a preferred core for fixture and low-end furniture applications including Ready-To-Assemble furniture. It is also used in selected kitchen cabinet components.
