Glyceryl monostearate is a white waxy flake or bead solid, insoluble in water, mixed with hot water by strong oscillation can be dispersed in water, is an oil-in-water emulsifier. Soluble in hot organic solvents ethanol, benzene, acetone and mineral and stationary oils. The freezing point is not less than 54 ° C. Glyceryl monostearate is often used in plastic resins.
Beite Chemical, which supplies monoglycerides, points out that glyceryl monostearate applications have the following advantages in plastic resins:
(1) Antistatic: Fast migration in plastic resin, long duration, can reduce surface resistance to reduce static electricity formation and accumulation, so it has a fast and long-term antistatic reduction dust adsorption function, as an antistatic agent in plastics, dust inhibitor.
(2) Excellent surface activity, in the plastic resin to make the film surface easy to wet, remain transparent, air condensation water droplets can be left along the film, so it has good sealing and printing, keep transparent and beneficial light transmission, can be used as a long-term anti-fogging agent anti-drip agent.
(3) Good greaseability: compatible with resin molecules, reduce intermolecular friction, reduce melt viscosity, shorten the production cycle, high yield, as internal and external lubricants, mold release agents.
(4) Excellent emulsification: Together with the foaming agent, it can make the foam structure uniform and delicate, reduce the shrinkage of the bubbles, especially in the winter when the temperature is low, the anti-shrinkage ability is strong, so that the product is bright and smooth, saving raw materials, as a foaming agent anti-shrinkage agent.
(5) Resin compatibility, can penetrate deep into the resin molecules, increase flexibility, can improve melting and injection molding, so it can be used as a plasticizer, modifier.
(6) Made of natural vegetable oil as raw material, odorless and tasteless, produced according to food additives, it is safe and non-toxic, and can be added to food packaging plastics.
