In the early 1970's Germany will custom polyurethane two-component liquid reaction molding technology, that is, RIM-PU technology commercialization to really promote the development of the custom polyurethane industry. Two-component rigid polyurethane liquid reaction molding process coup the traditi

Polyurethane rigid foam in the state before molding is two kinds of liquid, in the molding of these two kinds of liquid mixing, through the polyurethane spraying machine to become a solid raw material, so the construction molding method is more mobile. As long as it is not crushed polyurethane rigid

Rigid polyurethane foam is widely used in Europe and the United States for building roofs, walls, ceilings, floors, doors and windows, and other thermal insulation materials because of its light weight, low thermal conductivity, good heat resistance, aging resistance, easy to bond with other substra

Polyurethane foam insulation molding is to stir materials at room temperature to make them mix and react, and then quickly pour them into the space that needs to be molded. During the construction process, the reaction foaming time should be controlled so that the stirred mixture is poured into the

PU rigid foam composite polyether is one of the main raw materials of polyurethane insulation materials. PU rigid foam composite polyether is also called white material, together with polymer MDI, it is called black and white material. Black and white materials are suitable for building heat preserv
