PU synthetic leather is how to develop and progress? In addition to the production process, equipment, substrate and other continuous innovation, perhaps more important is the development of additives, innovation.
The additives mentioned in this article include not only the additives and functional materials, but also the surface treatment agents, special resins and the like which are prepared by blending or synthesizing the additives and the functional materials with ordinary PU resin. Its use includes PU resin additives and PU synthetic leather additives.
In general, PU synthetic leather innovation as follows:
Innovative additives to the process of PU synthesis = PU resin -> + innovative innovative additives such as the base fabric + filler + Toner -> by a variety of innovative manufacturing process = PU synthetic leather.
Thus, the development of additives in the development of PU synthetic leather plays a vital role.
Additives classification: Additives are generally divided into the following five categories:
First, solve the fault class. Such as: defoamer, wetting agent, anti-pin agent, leveling agent, wet with fixing agent, removal of DMF additives, even foam additives, anti-adhesive, interfacial fusion agent, tackifier, dispersant and many more. This kind of material in the PU resin and PU synthetic leather manufacturing process plays a vital role, without them, PU resin and PU synthetic leather can not be normal production.
