Glyceryl monostearate (monoglyceride) is white waxy Solid flakes or beads, insoluble in water, can be dispersed in water by strong oscillation with hot water. It is a water-in-oil emulsifier. Soluble in hot organic solvents ethanol, benzene, acetone, mineral oil and fixed oil. The freezing point is not lower than 54℃.
Applications and advantages of monoglycerides in the plastic industry:
1. Antistatic: it migrates quickly in plastic resins, has a long effect, and can reduce The surface resistance reduces the formation and accumulation of static electricity, so it has the function of fast and long-lasting antistatic to reduce dust adsorption, and can be used as an antistatic agent and dustproof agent in plastics.
2. Excellent surface activity: in the plastic resin, the surface of the film is easy to wet and remains transparent. Air condensation water droplets can flow down the film, so it has good sealing and printing properties. Maintaining transparency is beneficial to light transmission. Can be used as a long-lasting anti-fog and anti-drip agent.
3. Good grease properties: compatible with resin molecules, reducing intermolecular friction and melt viscosity, which can shorten the production cycle and increase the yield. It can be used as an internal and external lubricant and release agent.
4. Excellent emulsification: together with the foaming agent, it can make the foam structure uniform and delicate, reduce bubble shrinkage, especially in winter when the temperature is low, it has strong anti-shrinkage ability, making the product bright, clean and smooth. Save raw materials and serve as an assistant foaming agent and anti-shrinkage agent.
5. Resin compatibility, it can penetrate deeply into the resin molecules, increase flexibility, and improve melting and injection molding, so it can be used as a plasticizer and modifier.
6. Made of natural vegetable oil, it is odorless and tasteless. It is produced as a food additive, so it is safe and non-toxic and can be added to food packaging plastics.
