With the growing popularity of plastic industry, PU glue as a new generation of adhesives, its scope of application is also more and more widely, such as aircraft, car interior parts seats, shoes, outsole and so on. The production equipments of PU glue are generally used reactor, planetary dispersing mixing machine (dual planetary powerful mixer), hydraulic discharge machine, filling machines and other equipments. Now let us talk something about the production of PU glue and how to choose it.
PU glue is commonly known as white glue, and its chemical name is polyurethane resin. It has excellent adhesion fastness, good heat and weather resistance, colorless and translucent, environmentally friendly non-toxic, easy to operate, suitable for assembly line production. PU polyurethane generally not only includes glue making process by planetary dispersing mixing machine (dual planetary powerful mixer), but also has resin making process by reactor.
The production process of water-based PU glue is generally put the materials in firstly, then in the reactor mixing, heating, cooling, discharge, as well as packaging process. The production process of oil PU (polyurethane) is generally put the materials in firstly, then in the reactor making resin, and in the planetary dispersing mixing machine (dual planetary powerful mixer) to do base material and glue. The last process needs hydraulic discharge machine (with vacuum cover), filling and packaging. As the polyurethane glue is extremely sensitive to water, the excess water must be removed before the packaging process. If you are interested in making PU glue, kindly welcome your inquiry!
