white or cream-like waxy flakes with the odour of fatty, free flowing, poisonless. Disperse in hot water, soluble in hot alcohol. M.P. 58-63C.
2. Functions and effectiveness of Glycerol Monostearate(GMS) :
Plastic assistant is a kind of multi-purpose and multi-function plastic additive and also the ideal subsidiary raw material for modern plastic industry. Its functions and effectiveness are as followed:
1) Being as foaming promoter and anti-shrinkage.
The plastic assistant is the ideal foaming promoter and anti-shrinkage agent:
In order to meet the requirement of the environment, Freon foaming agent will be replaced step by step in the future. The plastic additive can be the foaming agent for the high foaming polyethylene and polystyrene. It performs well if admixed with butane or other foaming agents. Products inlayed with plastic additive are smooth & clean in exterior and have no contractibility.
2) Being as lubrication assistant and antistatic
The plastic assistant is an excellent lubricant that diminishes the friction among the polymer molecules, decreases the polymer melt viscosity and increases the fluidity. It has good features of good compatibility with resins, fine dispersion and is suitable for transparent products, etc. Besides, it antistatic feature is able to decline the formation and accumulation of static electricity so that is can make the plastic products decrease the adsorption of the dirt and maintain the exterior transparent and clean. The effectiveness of this feature is really obvious.
3) Being as anti-atomization and anti-trickle
The atomization formed in the surface of farm plastic film not only prevents the irradiation of the sunshine but also will damage the crops seriously by the condensed water. It has an excellent atomization function. Through its surfactant ability, the water condensed in the film surface can drop down along the humid film, avoid falling down directly.
4) Being as plasticization assistant and modification assistant
It has a good compatibility with many plastic materials including P.E, P.P, PVC and P.S. With the use of the plastic additive, it can make your products more flexibility and the exterior more beauty. It can get a good effectiveness using it as the plasticization and modifying assistant for cellulose nitrate, alkyd resin, nylon products, engineering plastics.
