What are the internal lubricants for nylon?

With the continuous development of modified nylon processing technology at home and abroad and the massive application of plastic processing equipment, lubricants play an indispensable role in order to improve processing speed, reduce energy consumption and improve the quality of products, especially the appearance.

Nylon lubricant is a kind of substance that can form an isolation layer between surface and surface or repair the uneven surface, generally divided into internal lubricant and external lubricant, which is mainly for the reason of friction resistance generated by: friction between modified nylon molecules as internal friction, friction between modified nylon materials and machinery and equipment as external friction.

Internal lubricant is added to the material in a certain proportion and stirred well in the ingredients before plastic processing to reduce the friction between resin molecules and play the role of lubrication. There are two kinds of external lubricants, one is to wipe the lubricant on the surface of the mold during the molding process to form a film on the metal surface to isolate the melt from the equipment and not to get on the equipment. One is a substance that has very little compatibility with the polymer and migrates easily from the inside of the polymer to the surface during processing, thus forming an isolation layer that is added before batching and migrates to the surface during processing to provide lubrication.

Most lubricants have both internal and external lubrication, just with different emphasis, and it is difficult to determine which category a particular lubricant belongs to. Regardless of which category it is, its role is to reduce viscosity and prevent the melt from sticking to the equipment, which can invariably improve quality and productivity. Lubricants are indispensable additives for the production and use of modified nylon.

Lubricant is an indispensable auxiliary for modified nylon, Nanjing Tianshi found that although there are many different lubricants in the market, but mostly single lubricant, domestic and foreign research on it is still relatively small, there is still a lot of potential in the future on the road of scientific and technological progress.
