Applicable Base Polymer Properties

Blood glues are preferably made from soluble dried beef blood, a byproduct of meat packaging operation. Blood glues are used to manufacture plywood and other wood products. Blood glues are of little commercial importance in most countries, but they are still used in certain regions for the manufacture of interior grade plywood. When modified with phenolic resins blood glues provide weather proof and mold proof bonds.
