In daily life, people divide gelatin into edible gelatin, medicinal gelatin, photographic gelatin and industrial gelatin. Among them, industrial gelatine can be divided into skin gelatine, bone gelatine, hot soluble gelatine powder, gelatine for protein, gelatine for feed, gelatine for matches, etc.

Industrial gelatin is a kind of fine chemical, which is a gelatin product classified according to the different uses of gelatin. It is a light yellow or brown granule without unpleasant odor and no impurities visible to the naked eye. It has a molecular weight of 100,000-100,000 and contains 18 amino acids, with a water and inorganic salt content of less than 16% and a protein content of more than 82%, making it an ideal source of protein.

Uses of industrial gelatin:First, it is used in the match manufacturing industry, mainly using the foaming nature of the gel to form pores and combine with oxidizers, igniters and fillers to make it ignite instantly. The second is as an adhesive, using its high strength, high elasticity and high toughness to produce sand cloth, sand paper, bonding wood, binding books, for gift box assembly line, musical instruments, furniture industry.

The third is electrolysis, which helps produce smooth and dense anodic precipitation by adding electrolyte to eliminate production losses. The fourth, used in textile fabrics, can form a film on the yarn bundle to increase the toughness, strength, smoothness and elasticity of the fiber and prevent breakage. Fifth, with dichromate to make negative photosensitive corrosion-resistant films. Sixth, hydrolyzed proteins are extracted and used as additives.

In a word, industrial gelatin is widely used in various products in the industries of plate, furniture, match, feed, packaging, paper making, textile, silk, printing and dyeing, printing, ceramics, petroleum, daily chemical, coating, metallurgy, etc. It mainly plays the role of thickening, stabilizing, cohesion, blending, polishing, sizing, bonding and water fixing.
