Ingredients and properties

Main ingredients: The main component of bone glue is collagen, which is a natural protein composed of multiple amino acids. In addition, bone glue also contains a small amount of minerals, fats and other impurities.

Physical properties: Bone glue is usually a light yellow to brown solid with a certain degree of transparency. It is hard and brittle at room temperature, and gradually softens after heating, with good viscosity. The melting point of bone glue is generally around 40-50℃, and its aqueous solution has a high viscosity, which increases with the increase of concentration.

Chemical properties: Bone glue has good chemical stability, but under conditions such as acid, alkali or high temperature, hydrolysis may occur, causing the collagen molecular chain to break, thereby affecting its adhesive properties. Bone glue can form complexes with many metal ions, and this property can be used to improve its performance or achieve specific functions in some applications.
