Monoglycerides (GMS)
Product description:
Glycerin monostearate (English name: Glycerin monostearate, abbreviation: GMS), the scientific list of monoglycerides, is the abbreviation of glycerin monostearate, with a molecular weight of 358. In addition to monoester, it also contains di Glycerides and triglycerides, tasteless, odorless, non-toxic. The content of industrial grade monoglyceride is generally 40-42%, the content of diglyceride is 35-45%, the content of triglyceride is 10-15%, and the content of free glycerol is 1-7%. When used in industry, the lubricating effect of monoglycerides is obvious, (the rest of the ingredients also have lubricating effects), so it is collectively called monoglycerides, also known as monoglycerides and glyceryl stearates, which are mainly used as lubricants in industrial production and are prohibited from being used in food , Cosmetics, dairy products added.

Features:
1. No frosting, no precipitation, good compatibility with plastic and rubber.
2. Good lubricating effect, can replace stearic acid and paraffin.
3. Low melting point, reducing energy consumption during production and processing.
4. Cheap price, lower production cost.
Applications:
1. Monoglycerides are used as lubricants in composite lead salt stabilizers and calcium zinc stabilizers, and the addition amount is 2%-10%, replacing part of stearic acid and paraffin.
2. Monoglycerides are used as internal and external lubricants in PVC pipe fittings, pipes, profiles, and plates, and can replace stearic acid. The amount added to pipe fittings is 2%, and the amount added to pipes, profiles, and plates is 0.5-1%. It acts as an internal lubricant when heating and melting, making the product evenly dispersed inside, and acts as an external lubricant during extrusion molding, making the surface of the product bright.
3. The amount of powdered monoglyceride used in ACR is relatively large, and the amount added is 5-20%.
4. Monoglyceride In the production of agricultural greenhouse film, monoglyceride is the main raw material of the dripping agent, and the addition amount is 40-50%.
5. Monoglyceride can be used as a release agent in rubber products to make the surface of the product bright and easy to release the mold. The addition amount is 1-2%. Some manufacturers add monoglyceride to the release agent, and the addition amount is 20-30%. .
6. As a textile printing and dyeing auxiliary, monoglyceride is the best anti-tarnish and softener for fabrics, and the addition amount is 3-5%.
7. Used as an antistatic agent in plastic products, the addition amount is 1-2%, the addition amount in antistatic masterbatch is 10-15%, and the addition amount in the production of solid antistatic agent is 30-40%.
Packing:
Woven bag, 25kg/bag.
