Glyceryl monostearate appears as white waxy flakes or solid beads , insoluble in water, can be dispersed in water by strong shaking with hot water, and 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℃. Glyceryl monostearate is often used in plastic resins.
The supply of monoglycerides points out: Glyceryl monostearate has the following advantages and characteristics when used in plastic resins:
(1) Antistatic : It migrates quickly in plastic resins and has a long effect. It can reduce surface resistance and reduce the formation and accumulation of static electricity. Therefore, it has the function of fast and long-lasting antistatic and reducing dust adsorption. It can be used as an antistatic agent and dustproof agent in plastics.
(2) Excellent surface activity makes the surface of the film easy to wet in the plastic resin and remains transparent. Air condensation water droplets can remain along the film, so it has good sealing and printing properties and is beneficial to maintaining transparency. It is light-transmitting and 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 from 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.
