The Lubricant-Polyhydroxy Alcohol Fatty Acid Ester

Description

The lubricant-Polyhydroxy Alcohol Fatty Acid Ester is an important plastic additive, can improve the flow of molten material, and thus

improve the stability of floor production, improve output and the quality of finished products.

Characteristics of lubricant

Polymers usually have high viscosity after melting. In the process of processing, when the melted polymer passes through narrow slots,

gates, and other runners, the polymer melt must produce friction with the surface of the processing machinery. Some friction is very

harmful to the processing of the polymer. These frictions make the melt fluidity lower and at the same time strict. Heavy friction can

make the film surface rough, lacking luster or rubbing. Therefore, it is necessary to add additives to improve lubricity, reduce friction

and reduce interfacial adhesion.This is the lubricant. In addition to improving fluidity, lubricants can also play the role of melt promoter,

anti-adhesion, and anti-static agent, smoothing agent and so on.

Application of lubricant

Lubricants have many functions in the practical processing of plastics. For example, in mixing and calendering, they can prevent the polymer

from sticking to the barrel, inhibit friction heat generation, reduce mixing torque and load, and prevent thermal degradation of polymer materials.

In extrusion moulding, it can improve the fluidity, improve the adhesion of polymer materials to barrels and dies, and prevent and reduce the retention.

In addition, it can improve the appearance and luster of the film.
